The MAX1437 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 MAX1437 operates from a 1.8V single
supply and consumes only 768mW (96mW 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 MAX1437 features a power-down
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 PLL
generates the high-speed serial low-voltage differential
signal (LVDS) clock.
The MAX1437 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.
