AD4632-24BBCZ

Analog To Digital Converters (ADC) Overview

The AD4632-24BBCZ is a dual-channel, simultaneous sampling, 24-bit successive approximation register (SAR) analog-to-digital converter. It operates at a maximum throughput of 500 kSPS per channel and guarantees ±0.9 ppm integral nonlinearity (INL) with no missing codes across the −40°C to +125°C temperature range. The device features Easy Drive™ technology for improved settling and supports both single-ended and differential inputs. It integrates a precision reference buffer and utilizes a Flexi-SPI interface compatible with 1.2 V to 1.8 V logic levels.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix matches the required package and tape-and-reel configuration. Confirm voltage supply requirements align with the internal reference buffer settings. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS SAR architecture.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel synchronization and high DC accuracy are required. The AD4632-24 offers lower throughput than the AD4630-24 variant but maintains identical 24-bit precision. Consider the integrated reference buffer to simplify external component selection and reduce board space.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD4630-24/AD4632-24 family of high-performance SAR ADCs. The AD4632-24 is the dual-channel variant optimized for 500 kSPS operation, whereas the AD4630-24 supports up to 2 MSPS. Both share the same pinout and feature set regarding accuracy and interface capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4630-24 serves as a higher-speed alternative within the same package. For single-channel applications, the AD4030-24 provides comparable performance. Ensure any substitute maintains the 64-ball CSP_BGA footprint and Flexi-SPI compatibility.
