General Description
The MAX1190 is a 3.3V, dual 10-bit analog-to-digital con-
verter (ADC) featuring fully differential wideband track-
and-hold (T/H) inputs, driving two ADCs. The MAX1190 is
optimized for low power, small size, and high-dynamic
performance for applications in imaging, instrumentation,
and digital communications. This ADC operates from a
single 2.8V to 3.6V supply, consuming only 492mW while
delivering a typical signal-to-noise and distortion (SINAD)
of 57dB at an input frequency of 60MHz and a sampling
rate of 120Msps. The T/H driven input stages incorporate
400MHz (-3dB) input amplifiers. The converters can also
be operated with single-ended inputs. In addition to low
operating power, the MAX1190 features a 3mA 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 applied ref-
erence, if desired, for applications requiring increased
accuracy or a different input voltage range.
The MAX1190 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 con-
trol pin. The device provides for a separate output power
supply of 1.7V to 3.6V for flexible interfacing with various
logic families. The MAX1190 is available in a 7mm
7mm, 48-pin TQFP-EP package, and is specified for the
extended industrial (-40°C to +85°C) temperature range.
Pin-compatible lower speed versions of the MAX1190 are
also available. Refer to the MAX1180–MAX1184 data
sheets for 105Msps/80Msps/65Msps/40Msps. In addition
to these speed grades, this family includes two multi-
plexed output versions (MAX1185/MAX1186 for
20Msps/40Msps), for which digital data is presented
time-interleaved and on a single, parallel 10-bit output
port.
For lower speed, pin-compatible, 8-bit versions of the
MAX1190, refer to the MAX1195–MAX1198 data sheets.
