The MAX1437B octal, 12-bit analog-to-digital converter
(ADC) features fully differential inputs, a pipelined
architecture, and digital error correction incorporating a
fully differential signal path. This ADC is optimized for
low-power and high-dynamic performance in medical
imaging instrumentation and digital communications
applications. The MAX1437B operates from a 1.8V single
supply and consumes only 768mW (96mW per
channel) while delivering a 70.2dB (typ) signal-to-noise
ratio (SNR) at a 5.3MHz input frequency. In addition to
low operating power, the MAX1437B features a lowpower
standby mode for idle periods.
An internal 1.24V precision bandgap reference sets the
full-scale range of the ADC. A flexible reference structure
allows the use of an external reference for applications
requiring increased accuracy or a different input
voltage range. The reference architecture is optimized
for low noise.
A single-ended clock controls the data-conversion
process. An internal duty-cycle equalizer compensates
for wide variations in clock duty cycle. An on-chip
phase-locked loop (PLL) generates the high-speed serial
low-voltage differential signal (LVDS) clock.
The MAX1437B has self-aligned serial LVDS outputs for
data, clock, and frame-alignment signals. The output
data is presented in two’s complement format.
The MAX1437B offers a maximum sample rate of
50Msps. This device is available in a small, 10mm x
10mm x 0.8mm, 68-pin thin QFN package with exposed
pad and is specified for the extended industrial (-40°C
to +85°C) temperature range.
