Overview
The AD7193BCPZ-RL7, produced by 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 both four differential inputs and eight pseudo differential inputs, and includes an on-chip channel sequencer that enables simultaneous conversion of multiple channels, simplifying communication with the device.
The AD7193BCPZ-RL7 operates with a power supply range of 3 V to 5.25 V and consumes a current of 4.65 mA. It is available in a 32-lead LFCSP package and offers a flexible digital filter with options such as fast settling and zero latency. The output data rate can be varied from 4.7 Hz to 4.8 kHz, depending on the selected filter options.
