    • Demo Board for LTC2288 - Dual 10-Bit, 65Msps Low Noise 3V ADC

    Overview

    The Demonstration circuit 851 (DC851A-P) supports LTC2288, Dual 10-Bit, 65Msps Low Noise 3V ADC. It features the LTC2288 high speed, high dynamic range ADC.The circuitry on the analog inputs is optimized for analog input frequencies range from 1MHz to 70MHz.

    The LTC2288 is a 10-bit 65Msps, low noise dual 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2288 is a perfect for demanding imaging and communications applications with AC performance that includes 61.8dB SNR and 85dB SFDR for signals at the Nyquist frequency.

    DC specs include ±0.1LSB INL (typ), ±0.05LSB DNL (typ) and ±0.6 LSB INL, ±0.5 LSB DNL over temperature. The transition noise is a low 0.07LSBRMS.

    A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic. An optional multiplexer allows both channels to share one digital output bus.

    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.
