MAX1186 pdf datasheet

The MAX1186 is a 3V, dual 10-bit analog-to-digital converter
(ADC) featuring fully-differential wideband trackand-
hold (T/H) inputs, driving two pipelined, nine-stage
ADCs. The MAX1186 is optimized for low-power, high
dynamic performance applications in imaging, instrumentation,
and digital communication applications. This
ADC operates from a single 2.7V to 3.6V supply, consuming
only 105mW while delivering a typical signal-tonoise
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 amplifiers.
The converters may also be operated with singleended
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.
