The MAX1196 is a 3V, dual 8-bit analog-to-digital con- verter (ADC) featuring fully differential wideband track- and-hold (T/H) inputs, driving two ADCs. The MAX1196 is optimized for low power, small size, and high-dynamic performance for applications in imaging, instrumenta- tion, and digital communications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 87mW while delivering a typical signal-to-noise and dis- tortion (SINAD) of 48.4dB at an input frequency of 20MHz and a sampling rate of 40Msps. The T/H driven input stages incorporate 400MHz (-3dB) input ampli- fiers. The converters can also be operated with single- ended inputs. In addition to low operating power, the MAX1196 features a 3mA sleep mode as well as a 0.1µA power-down 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 this internal or an externally applied reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1196 features parallel, multiplexed, CMOS- compatible three-state outputs. The digital output format can be 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 MAX1196 is available in a 7mm × 7mm, 48-pin TQFP package, and is specified for the extended indust
