AD7951BSTZ

Overview

The AD7951BSTZ is a 14-bit, 1 MSPS PulSAR ADC from Analog Devices Inc. It features multiple programmable input ranges (5 V, 10 V, ±5 V, ±10 V) selectable via pins or serial interface. The device operates with a single 5 V analog/digital supply and includes an internal 5 V reference. Throughput reaches 1 MSPS in warp mode, 800 kSPS in normal mode, and 670 kSPS in impulse mode. Key performance metrics include an INL of ±0.3 LSB typical, SNR of 85 dB at 2 kHz, and power dissipation of 235 mW at full speed. It supports parallel and serial interfaces.
