The Demonstration circuit 851 (DC851A-V) supports LTC2282, Dual 12-Bit, 105Msps Low Power 3V ADC. It features the LTC2282 high speed, high dynamic range ADC. The circuitry on the analog inputs is optimized for analog input frequencies range from 70MHz to 140MHz.

The LTC2282 is a 12-bit 105Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2282 is perfect for demanding imaging and communications applications with AC performance that includes 70.1dB SNR and 85dB SFDR for signals at the Nyquist frequency.

DC specs include ±0.4LSB INL (typ), ±0.2LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.3LSBRMS. A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic.

A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.

Note: The DC851 demonstration circuit board should have the following jumper settings as default: JP1: Mode: Vdd. 2s complement, Clock duty stabilizer, off, JP2: Sense A: Vdd, (2V P-P input range), JP3: Sense B: Vdd, (2V P-P input range)

Key Applications: Wireless and Wired Broadband Communication, Imaging Systems, Spectral Analysis, Portable Instrumentation.
