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, nine-

stage ADCs. The MAX1180 is optimized for low-power,

high-dynamic performance applications in imaging,

instrumentation, and digital communication applica-

tions. The MAX1180 operates from a single 2.7V to 3.6V

supply, consuming only 413mW, while delivering a typi-

cal signal-to-noise ratio (SNR) of 58.5dB at an input fre-

quency 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 interfac-

ing. The MAX1180 is available in a 7mm

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 mul-

tiplexed output version (MAX1185), for which digital

data is presented time-interleaved on a single, parallel

10-bit output port.
