instrumentation, and digital communication applica- tions. The MAX1180 operates from a single 2.7V to 3.6V Low Power supply, consuming only 413m W, while delivering a typi- 125m A (Normal Operation) cal signal-to-noise ratio (SNR) of 58.5d B at an input fre- 2.8m A (Sleep Mode) quency of 20MHz and a sampling rate of 105Msps. The 1µA (Shutdown Mode) T/H driven input stages incorporate 400MHz (-3d B)
