The MAX1183 is a 3V, dual 10-bit analog-to-digital converter
(ADC) featuring fully differential wideband trackand-
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 ? 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 timeinterleaved
and on a single, parallel 10-bit output port.
