AD9253BCPZ-125

Overview

The AD9253BCPZ-125 is a quad, 14-bit analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit. It operates at conversion rates up to 125 MSPS and requires a single 1.8 V power supply. The device features a 650 MHz full-power analog bandwidth and a 2 V p-p differential input voltage range. Key performance metrics include a signal-to-noise ratio of 74 dB and a spurious-free dynamic range of 90 dBc at Nyquist frequencies. Differential nonlinearity is typically ±0.75 LSB, while integral nonlinearity is ±2.0 LSB. It utilizes serial LVDS outputs and supports individual channel power-down modes.
