MAX1184 Datasheet | Maxim Integrated

Description The MAX1184 is a +3V, dual 10-bit analog-to-digital converter (ADC) featuring fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, 9stage ADCs. The MAX1184 is optimized for low-power, high-dynamic performance applications in imaging, instrumentation, and digital munication applications. This ADC operates from a single +2.7V to +3.6V supply, consuming only 105m W while delivering a typical signal-to-noise ratio (SNR) of 59.5d B at an input frequency of 7.5MHz and a sampling rate of 20Msps. 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 MAX1184 features a 2.8m A sleep mode as well as a 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 the internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1184 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 MAX1184 is available in a 7mm x 7mm, 48pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range. Pin-patible higher speed versions of the MAX1184 are also available. Please refer to the MAX1180 data sheet for 105Msps, the MAX1181 data sheet for 80Msps, the MAX1182 data sheet for 65Msps, and the MAX1183 data sheet for 40Msps. In addition to these speed grades, this family includes a 20Msps multiplexed output version (MAX1185), for which digital data is presented time-interleaved on a single, parallel 10-bit output port.
