Overview
The AD4116BCPZ from Analog Devices Inc. is a 24-bit, Sigma-Delta analog-to-digital converter (ADC) designed to integrate an analog front end (AFE) for various input configurations. This ADC is capable of handling six fully differential or eleven single-ended, high impedance (≥10 MΩ) bipolar, ±10 V voltage inputs, along with additional direct ADC inputs for lower input ranges. The device is known for its precision performance, achieved through the proprietary iPassives® technology, and its ability to operate with a single power supply, making it suitable for galvanically isolated applications. The AD4116BCPZ is housed in a 40-lead, 6 mm × 6 mm LFCSP package and operates within a temperature range of −40°C to +105°C.
