General Description

The MAX19527 is an octal, 12-bit analog-to-digital converter (ADC), optimized for the low-power and high-dynamic performance requirements of medical imaging instrumentation and digital communications applications. The device operates from a single 1.8V supply and consumes 440mW (55mW per channel), while providing a 69dBFS signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the device features programmable power management for idle states and reduced-channel operation.
