This device preserves signal integrity at the receiver by reestablishing full output levels, and it can reduce total system jitter (TJ) by squaring the signal. Selectable preemphasis and programmable equalization allow the signal to be redriven across long traces, thereby increasing layout flexibility. The MAX4951BE is designed for applications such as notebook computers in which the user needs to push the signal through docking-station connectors, onto a mezzanine board, and through an external connector while being compliant with the Serial ATA International Organization: Serial ATA Revision 3.0 specification. It is also well suited for desktops and servers that must carry signals over long cables and boards while overcoming losses on the PCB and in the eSATA connector.

The MAX4951BE provides the ability to enter a low-power standby mode when the integrated cable-detect pin is either pulled high or left unconnected. This capability reduces the supply current significantly and conserves power in mobile environments such as notebooks and netbooks. To extend power savings, the MAX4951BE features a dynamic power-down mode that automatically shuts down circuitry when an input signal is not present.

The MAX4951BE supports SATA out-of-band (OOB) signaling using high-speed amplitude detection on the inputs, and amplitude squelch on the corresponding outputs. Input signals of 50mV_P-P or less are detected as off and not passed to the output, whereas signals of 150mV_P-P or more are detected as on and passed through the output. This approach prevents the system from responding to unwanted noise while still allowing OOB signals to transmit through the MAX4951BE.

The MAX4951BE also includes ±8kV (typ, HBM) ESD protection on all pins to prevent damage to the device and the eSATA port. The device operates from a single 3.3V supply, and is fully specified over the 0°C to +70°C commercial temperature range. It is available in an ultra-small, 4mm x 4mm, 20-pin TQFN package and is backwards compatible with the MAX4951 and MAX4951AE. Prices start at $1.50 (1000-up, FOB USA).

This innovative architecture minimizes power consumption while avoiding the signal discontinuity problems that plague other Class H implementations. Providing the industry's best efficiency (87%, typ) and audio quality, the MAX97000–MAX97002 are ideal for cellular phones, portable media players (PMPs), and other applications that require high audio quality, output power, and efficiency.

In addition to boosting efficiency, the DirectDrive II architecture eliminates the need for large DC-blocking capacitors by producing a ground-referenced output from a single supply. Meanwhile, spread-spectrum modulation and active emissions limiting significantly reduce EMI in the Class D output stage, thus enabling designs to meet EN 55022B standards without LC filters or shielding.** The integrated low-noise, analog DPST audio switch avoids the expense of an external switch and allows the Class D amplifier to be bypassed to reduce power consumption.

The MAX97000–MAX97002 feature high RF/TDMA noise rejection and best-in-class click-and-pop suppression with no audible artifacts at power on/off , both of which simplify the design iteration process. The subsystems also feature input mixing, volume control, and a flexible, user-defined input architecture with preamplifier gain settings. All controls are enabled through an I²C interface.

The MAX97000–MAX97002 deliver over 710mW of output power from a 3.7V supply into an 8Ω load with 87% (typ) efficiency. The MAX97000 is packaged in a 2.0mm x 2.0mm, 25-bump WLP with a 0.4mm pitch; the MAX97001/MAX97002 are packaged in 2.0mm x 2.5mm, 20-bump WLP with a 0.5mm pitch. All devices are fully specified over the -40°C to +85°C extended temperature range. Prices start at $0.75 for the MAX97000, and at $0.83 for the MAX97001/MAX97002 (1000-up, FOB USA). An evaluation kit is available to speed designs.

Press Release - Maxim - Maxim's 1.7V digital potentiometers bring digital control and calibration to power-sensitive applications

rwang — Thu, 07 Oct 2021 02:52:29 GMT

Current Revision posted to Documents by rwang on 10/7/2021 2:52:29 AM

The MAX5391–MAX5393 operate from an industry-low 1.7V, allowing designers to enjoy the benefits of digital potentiometers in low-voltage systems.

SUNNYVALE, CA—February 4, 2010—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX5391/MAX5392/MAX5393, the industry's lowest voltage digital potentiometers. This family of dual, 256-tap, volatile digital potentiometers operate from a single 1.7V to 5.5V power supply, which makes them ideal for replacing mechanical potentiometers and DACs in power-sensitive applications. With unique features such as a small package size, low operating voltage, and low supply current, the MAX5391–MAX5393 are well positioned to serve the portable consumer and industrial battery-backup markets. Suitable applications include LCD calibration, volume control, system circuit calibration and trim, amplifier offset, and gain and bias control.

Replacing mechanical potentiometers with low-voltage digital potentiometers streamlines manufacturing

Designers of low-voltage (less than 2.3V) systems, such as industrial battery-backup or portable consumer applications, have previously used mechanical potentiometers or DACs because they can operate from 1.8V. These low-voltage devices allow system designers to meet tight power-consumption specs; however, their use has come at a cost. With mechanical potentiometers, calibration is labor intensive and prone to error, as it typically involves analog adjustments using a screwdriver.

Digital potentiometers have many advantages over their mechanical counterparts: they enable processor control and programmability, they guarantee greater reliability and accuracy, and they offer packaging options that facilitate automatic assembly. In short, they streamline the manufacturing process by eliminating the need for expensive and error-prone manual adjustments.

Yet, until now, designers have been forced to forgo the benefits of digital potentiometers in order to meet the stringent power-consumption requirements of low-voltage systems.

"The MAX5391–MAX5393 bring digital control and calibration to low-voltage systems," explained Jeremy Tole, Maxim's Director of Business Development for Data Converters. "They are the industry's first digital potentiometers to operate from a voltage as low as 1.7V. This capability, along with a small TQFN package, makes this family a space-saving alternative to mechanical potentiometers and some DACs in portable consumer and industrial battery-backup applications. Designers can now enjoy all of the benefits of digital potentiometers while still meeting their power-consumption specs."
