Maxim Integrated MAX1438B

The MAX1438B 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 MAX1438B operates from a 1.8V single supply and consumes only 913mW (114mW per channel) while delivering a 69.9dB (typ) signal-to-noise ratio (SNR) at a 5.3MHz input frequency.

GENERAL DESCRIPTION

In addition to low operating power, the MAX1438B 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.
