MAX12528 - Dual 80Msps 12-Bit IF/Baseband ADC

General Description

The MAX12528 is a dual 80Msps, 12-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers.

Key Features

  • a 330µW powerdown mode to conserve power during idle periods. A flexible reference structure allows the MAX12528 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 MAX12528 provides a common-mode reference to simplify design and reduce external component count in differential analog input circuit.

19-3643; Rev 0; 4/05 KIT ATION EVALU E L B AVAILA www.DataSheet4U.com Dual, 80Msps, 12-Bit, IF/Baseband ADC General Description The MAX12528 is a dual 80Msps, 12-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving internal quantizers. The MAX12528 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 supply, consuming only 726mW while delivering a typical 69.8dB signal-tonoise ratio (SNR) performance at a 175MHz input frequency. The T/H input stages accept single-ended or differential inputs up to 400MHz.
