The MAX9617/MAX9618 zero-drift, rail-to-rail operational amplifiers from Maxim Integrated Products are said to offer best-in-class power consumption to enable a new generation of portable medical devices.
The op amps achieve both a 10µV (max) input-offset voltage and an input-voltage noise of 1µVP-P from 0.1Hz to 10Hz. Designed to have minimal 1/f noise, the devices facilitate accurate low-frequency measurements and allow for optimization of active filter designs. Moreover, the precision of the MAX9617/MAX9618 will not degrade with time and temperature, as they both feature very low (5nV/°C, typ) input-offset-voltage drift.
Designed to operate from 1.8V to 5.5V supplies and consuming only 59µA of quiescent current per amplifier to extend battery life the MAX9617/MAX9618 op amps are suitable for a wide variety of portable medical applications in which high accuracy and low quiescent current are critical. They are also well suited for industrial applications, such as loop-powered systems, that require a combination of low power and precision.
These devices are available in 6-pin SC70 (single) and 8-pin SC70 (dual) packages.
