ADS1210PG4

Analog To Digital Converters (ADC) Overview

The ADS1210PG4 is a discontinued 24-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes delta-sigma architecture and features an integrated programmable gain amplifier (PGA). The device supports a single differential input channel with a maximum sampling rate of 16 kSPS. It operates on a 5V supply for both analog and digital sections and communicates via an SPI-compatible serial interface. The component is housed in an 18-pin plastic dual in-line package (PDIP) designed for through-hole mounting, suitable for precision data acquisition applications requiring high resolution.

Analog To Digital Converters (ADC) Procurement Notes

This component is officially obsolete and no longer in production. Verification should focus on identifying qualified replacement parts from the manufacturer's current portfolio. Sourcing requires checking for surplus stock or authorized distributors holding legacy inventory. Designers must evaluate pin compatibility and electrical specifications when selecting alternative devices to ensure system continuity without redesign.

Analog To Digital Converters (ADC) Selection Notes

Selection requires evaluating the trade-off between resolution and speed, as the 24-bit resolution limits the sampling rate to 16 kSPS. The fixed 5V supply requirement dictates power rail availability. Designers must consider the PDIP package constraints for PCB layout compared to surface-mount alternatives. Integration complexity is reduced by the internal PGA and clock, but external filtering may still be necessary for optimal noise performance.

Analog To Digital Converters (ADC) Part Context
