MAX1211ETL+T

The MAX1211 is a 3.3V, 12-bit analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) input, driving the internal quantizer.
The MAX1211 is optimized for low power, small size, and high dynamic performance in intermediate frequency (IF) sampling applications. This ADC operates from a single 3.0V to 3.6V supply, consuming only 358mW while delivering a typical signal-to-noise ratio (SNR) performance of 66dB at an input frequency of 175MHz.
The T/H driven input stage accepts single-ended or differential inputs. In addition to low operating power, the MAX1211 features a 13mW power-down mode to conserve power during idle periods.A flexible reference structure allows the MAX1211 to use its internal precision bandgap reference or accept an externally applied reference.
The MAX1211 supports both a single-ended and differential input clock drive. Wide variations in the clock duty cycle are compensated with the ADC’s internal duty-cycle equalizer.
The MAX1211 features parallel, CMOS-compatible outputs.
The digital output format is pin selectable to be either two’s complement or Gray code. A separate power input for the digital outputs accepts a voltage from 1.7V to 3.6V for flexible interfacing with various logic levels.
The MAX1211 is available in a 6mm x 6mm x 0.8mm, 40-pin thin QFN package with exposed paddle (EP), and is specified for the extended industrial (-40°C to +85°C) temperature range.
