ADS8422IBPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8422IBPFBTG4 is a 16-bit, 4-MSPS analog-to-digital converter (ADC) featuring pseudo-bipolar input and fully differential architecture. It integrates a precision internal reference and operates with a single 5V supply. The device utilizes a successive approximation register (SAR) structure to achieve high-speed conversion with low power consumption. Key electrical specifications include a maximum sampling rate of 4 MSPS, 16-bit resolution, and a full-scale input range compatible with pseudo-bipolar signals. It communicates via a parallel interface and is housed in a 48-pin TQFP package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS842x family of micro-power sampling ADCs from Texas Instruments. It shares architectural similarities with the ADS8411 but offers higher throughput and differential inputs. The 'G4' suffix indicates lead-free and RoHS-compliant manufacturing standards consistent with Texas Instruments' environmental guidelines.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8422IBPFBT is the non-green equivalent part number. Designers should verify that the G4 suffix does not alter pin compatibility or thermal characteristics, although these variants are typically functionally identical.
