Maxim Integrated MAX1182
The MAX1182 is a 3V, dual 10-bit analog-to-digital converter (ADC) featuring fully-differential wideband trackand-hold (T/H) inputs, driving two pipelined, 9-stage ADCs. The MAX1182 is optimized for low-power, highdynamic performance applications in imaging, instrumentation and digital communication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 195mW while delivering a typical signal-tonoise ratio (SNR) of 59dB at an input frequency of 20MHz and a sampling rate of 65Msps.

GENERAL DESCRIPTION
The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1182 features a 2.8mA sleep mode as well as a 1µA powerdown mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of the internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1182 features parallel, CMOS-compatible three-state outputs. The digital output format is set to two’s complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing. The MAX1182 is available in a 7mm x 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range. Pin-compatible higher and lower speed versions of the MAX1182 are also available.
