MAX12557 - Maxim Integrated Products

MAX12557 Dual 65Msps 14-Bit IF/Baseband ADC

The MAX12557 is a dual 3.3V, 14-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers. The MAX12557 is optimized for low power, small size, and high dynamic performance in intermediate frequency (IF) and baseband sampling applications. This dual ADC operates from a single 3.3V sup.

Features

a 166µW powerdown mode to conserve power during idle periods. A flexible reference structure allows the MAX12557 to use the internal 2.048V bandgap reference or accept an externally applied reference and allows the reference to be shared between the two ADCs. The reference structure allows the full-scale analog input range to be adjusted from ±0.35V to ±1.15V. The MAX12557 provides a common-mode reference to simplify design and reduce external component count in differential analog input circuits. The MAX12557 supports either a single-ended or differential input clock. User-selectable divide-b.
