The MAX1186 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, nine-stage
ADCs. The MAX1186 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 59.4dB at an input frequency of
20MHz and a sampling rate of 40Msps. Digital outputs
A and B are updated alternating on the rising (CHA)
and the falling (CHB) edge of the clock. The T/H driven
input stages incorporate 400MHz (-3dB) input ampli-
fiers. The converters may also be operated with single-
ended inputs. In addition to low operating power, the
MAX1186 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 ADCs. A flexible reference
structure allows the use of this internal or an externally
derived reference, if desired for applications requiring
increased accuracy or a different input voltage range.
The MAX1186 features parallel, multiplexed, CMOS-
compatible three-state outputs. The digital output for-
mat can be 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 MAX1186 is available in a
7mm x 7mm, 48-pin TQFP-EP package, and is speci-
fied for the extended industrial (-40°C to +85°C) tem-
perature range.
Pin-compatible, nonmultiplexed, high-speed versions of
the MAX1186 are also available. Please refer to the
MAX1180 data sheet for 105Msps, 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. For a pin-compatible lower
speed version (20Msps) of the MAX1186, please refer
to the MAX1185 data sheet.
