General Description

The MAX1126 quad, 12-bit analog-to-digital converter (ADC) features fully differential inputs, a pipelined architecture, and digital error correction. This ADC is optimized for low-power, high-dynamic performance for medical imaging, communications, and instrumentation applications. The MAX1126 operates from a 1.7V to 1.9V single supply and consumes only 563mW while delivering a 69.9dB signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1126 features an 813µA power-down mode for idle periods.
