Dual 10-Bit, 65Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs General Description Features

The MAX1182 is a 3V, dual 10-bit analog-to-digital con- Single 3V Operation

verter (ADC) featuring fully-differential wideband track- Excellent Dynamic Performance: and-hold (T/H) inputs, driving two pipelined, 9-stage 59d B SNR at f IN = 20MHz ADCs. The MAX1182 is optimized for low-power, high- 77d B SFDR at f IN = 20MHz dynamic performance applications in imaging, instru-

65m A (Normal Operation)

ADC operates from a single 2.7V to 3.6V supply, con- 2.8m A (Sleep Mode) suming only 195m W while delivering a typical signal-to- 1µA (Shutdown Mode) noise ratio (SNR) of 59d B at an input frequency of

0.02d B Gain and 0.25° Phase Matching (typ)

20MHz and a sampling rate of 65Msps. The T/H driven
