General Description
The MAX1195 is a 3V, dual, 8-bit analog-to-digital con-
verter (ADC) featuring fully differential wideband track-
and-hold (T/H) inputs, driving two ADCs. The MAX1195
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 2.7V to 3.6V supply, consuming only 87mW while
delivering a typical signal-to-noise and distortion (SINAD)
of 48.5dB at an input frequency of 20MHz and a sam-
pling rate of 40Msps. The T/H-driven input stages incor-
porate 400MHz (-3dB) input amplifiers. The converters
may also be operated with single-ended inputs. In addi-
tion to low operating power, the MAX1195 features a
3mA sleep mode as well as a 0.1μA 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 reference, if desired, for applications requiring
increased accuracy or a different input voltage range.
The MAX1195 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 MAX1195 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 MAX1195
are also available. Refer to the MAX1197 data sheet for
60Msps and the MAX1198 data sheet for 100Msps. In
addition to these speed grades, this family will include a
multiplexed output version (MAX1196, 40Msps), for
which digital data is presented time interleaved and on
a single, parallel 8-bit output port.
For a 10-bit, pin-compatible upgrade, refer to the
MAX1183 data sheet. With the N.C. pins of the MAX1195
internally pulled down to ground, this ADC becomes a
drop-in replacement for the MAX1183.
