Octal, 12-Bit, 40Msps, 1.8V ADC
with Serial LVDS Outputs
General Description
The MAX1436B 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 MAX1436B operates from a 1.8V sin-
gle supply and consumes only 743mW (93mW per
channel) while delivering a 69.9dB (typ) signal-to-noise
ratio (SNR) at a 5.3MHz input frequency. In addition to
low operating power, the MAX1436B features a low-
power standby mode for idle periods.
An internal 1.24V precision bandgap reference sets the
full-scale range of the ADC. A flexible reference struc-
ture allows the use of an external reference for applica-
tions 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 PLL
generates the high-speed serial low-voltage differential
signal (LVDS) clock.
The MAX1436B has self-aligned serial LVDS outputs for
data, clock, and frame-alignment signals. The output
data is presented in two’s complement or binary format.
The MAX1436B offers a maximum sample rate of
40Msps. See the Pin-Compatible Versions table below
for higher-speed versions. This device is available in a
small, 14mm x 14mm x 1mm, 100-pin TQFP package
with exposed pad and is specified for the extended
industrial (-40°C to +85°C) temperature range.
