  • 产品描述:
The MAX1183 is a 3V, dual 10-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine-stage ADCs. The MAX1183 is optimized for low-power, high dynamic performance applications in imaging, instrumentation, and digital communication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 120mW while delivering a typical signal-to-noise ratio (SNR) of 59.6dB at an input frequency of 20MHz and a sampling rate of 40Msps. 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 MAX1183 features a 2.8mA 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 this internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1183 features parallel, 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 MAX1183 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 lower and higher speed versions of the MAX1183 are also available. See Table 2 at end of data sheet for a list of pin-compatible versions. Refer to the MAX1180 data sheet for 105Msps, the MAX1181 data sheet for 80Msps, the MAX1182 data sheet for 65Msps, and the MAX1184 data sheet for 20Msps. In addition to these speed grades, this family includes a multiplexed output version, for which digital data is presented time-interleaved and on a single, parallel 10-bit output port.
