Product Introduction

Overview

The AD7193BCPZ from Analog Devices Inc. is a highly advanced, low-noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for high precision measurement applications. This device serves as a complete analog front end, featuring an on-chip low noise gain stage that allows signals of small amplitude to interface directly with the ADC. It supports four differential inputs or eight pseudo differential inputs and includes an on-chip channel sequencer, enabling simultaneous channel enablement and sequential conversion, which simplifies communication with the device.

The AD7193BCPZ operates with a flexible digital filter, including a fast settling option and a zero latency option. The output data rate can be varied from 4.7 Hz to 4.8 kHz, depending on the filter settings. The device is powered by a supply voltage ranging from 3 V to 5.25 V and consumes a current of 4.65 mA. It is available in 28-lead TSSOP and 32-lead LFCSP packages.
