MAX1180 pdf datasheet (Low-Pow

The MAX1180 is a 3.3V, dual 10-bit, analog-to-digital
converter (ADC) featuring fully-differential wideband
track-and-hold (T/H) inputs, driving two pipelined, ninestage
ADCs. The MAX1180 is optimized for low-power,
high-dynamic performance applications in imaging,
instrumentation, and digital communication applications.
The MAX1180 operates from a single 2.7V to 3.6V
supply, consuming only 413mW, while delivering a typical
signal-to-noise ratio (SNR) of 58.5dB at an input frequency
of 20MHz and a sampling rate of 105Msps. 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 MAX1180 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 the internal or external
reference, if desired for applications requiring
increased accuracy or a different input voltage range.
The MAX1180 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 MAX1180 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 higher and lower speed versions of the
MAX1180 are also available. Please refer to the
MAX1181 data sheet for 80Msps, the MAX1182 data
sheet for 65Msps, the MAX1183 data sheet for 40Msps,
and the MAX1184 data sheet 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.
