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. 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. 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 digital data is presented time-interleaved on a
single, parallel 10-bit output port.
