19-2094; Rev 1; 4/06 Dual 10-Bit, 65Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs MAX1182 General Description 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 munication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 195m W while delivering a typical signal-tonoise ratio (SNR) of 59d B at an input frequency of 20MHz and a sampling rate of 65Msps. The T/H driven input stages incorporate 400MHz (-3d B) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1182 Features a 2.8m A 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-patible three-state outputs. The digital output format is set to .. two’s plement 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-patible higher and lower speed versions of the MAX1182 are also available. Please refer to the MAX1180 datasheet for 105Msps, the MAX1181 datasheet for 80Msps, the MAX1183 datasheet for 40Msps, and the MAX1184 datasheet for 20Msps. In addition to these speed grades, this family includes a 20Msps multiplexed output version (MAX1185), for which...
