General Description
The MAX1184 is a 3V, dual 10-bit analog-to-digital con-
verter (ADC) featuring fully-differential wideband track-
and-hold (T/H) inputs, driving two pipelined, 9-stage
ADCs. The MAX1184 is optimized for low-power, high-
dynamic performance applications in imaging, instru-
mentation, and digital communication applications. This
ADC operates from a single 2.7V to 3.6V supply, con-
suming only 105mW while delivering a typical signal-to-
noise ratio (SNR) of 59.5dB at an input frequency of
7.5MHz and a sampling rate of 20Msps. 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 MAX1184
features a 2.8mA sleep mode as well as a 1A 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-compatible
three-state outputs. The digital output format is set to
two’s complement or straight offset binary through a sin-
gle control pin. The device provides for a separate out-
put power supply of 1.7V to 3.6V for flexible interfacing.
The MAX1184 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 speed versions of the MAX1184
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
MAX1183 data sheet for 40Msps. In addition to these
speed grades, this family includes a 20Msps multi-
plexed output version (MAX1185), for which digital data
is presented time-interleaved on a single, parallel 10-bit
output port.
