MAXIM MAX1183 Dual 10-Bit, 40Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs

19-2173; Rev 1; 7/06

Dual 10-Bit, 40Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs

General Description Features

The MAX1183 is a 3V, dual 10-bit analog-to-digital con- Single 3V Operation verter (ADC) featuring fully differential wideband track-

ADCs. The MAX1183 is optimized for low-power, high

73d B SFDR at f IN = 20MHz

dynamic performance applications in imaging, instrumen-

tation, and digital communication applications. This ADC Low Power:

operates from a single 2.7V to 3.6V supply, consuming 40m A (Normal Operation) only 120m W while delivering a typical signal-to-noise ratio 2.8m A (Sleep Mode) (SNR) of 59.6d B at an input frequency of 20MHz and a

1µA (Shutdown Mode)

sampling rate of 40Msps. The T/H driven input stages

0.02d B Gain and 0.25° Phase Matching

incorporate 400MHz (-3d B) input amplifiers. The convert-
