General Description

The MAX12527 is a dual 3.3V, 12-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers. The MAX12527 is optimized for low power, small size, and high dynamic performance in intermediate frequency (IF) and baseband sampling applications.
