AD4115BCPZ

Analog To Digital Converters (ADC) Overview

The AD4115BCPZ is a single-supply, multichannel, 24-bit Sigma-Delta analog-to-digital converter (ADC) with an integrated analog front end (AFE). It supports eight fully differential or sixteen single-ended voltage inputs with a ±10 V range and minimum 1 MΩ impedance. The device offers flexible output data rates from 2.5 SPS to 125 kSPS, achieving a channel scan rate of 24,845 SPS per channel. Key electrical parameters include an internal 2.5 V reference with ±0.12% initial accuracy at 25°C, AVDD supply range of 4.5 V to 5.5 V, IOVDD range of 2 V to 5.5 V, and total current consumption of 10.4 mA. It operates within a temperature range of −40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel configuration. Ensure compatibility with required operating temperatures and supply voltages before procurement. Cross-reference the datasheet revision to confirm all specifications match the intended application requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-precision, multi-channel signal acquisition with integrated signal conditioning. Consider the 125 kSPS maximum speed and 24-bit resolution for demanding measurement tasks. Verify that the system power supplies align with the AVDD (4.5 V–5.5 V) and IOVDD (2 V–5.5 V) requirements. Evaluate the need for internal versus external reference sources based on accuracy and cost constraints.

Analog To Digital Converters (ADC) Part Context

The AD4115 belongs to Analog Devices' family of high-performance, low-noise Sigma-Delta ADCs designed for industrial applications. It integrates proprietary iPassives® technology to achieve precision performance without external components. The device simplifies design by combining the ADC, multiplexer, and analog front end into a single 40-lead LFCSP package.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the official Analog Devices ordering guide for verified alternative part numbers within the AD411x series. Confirm pinout and register compatibility when substituting with other devices in the family.
