ADS1672IPAGG4

Analog To Digital Converters (ADC) Overview

The ADS1672IPAGG4 is a high-speed, 24-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a delta-sigma architecture to achieve a sampling rate of 625 kSPS with differential input capability. The device operates on dual power supplies: an analog supply ranging from 4.75 V to 5.25 V and a digital supply between 2.7 V and 3.3 V. Key performance metrics include a signal-to-noise ratio (SNR) of 105 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of 9.5 ppm. It features LVDS output and requires an external reference. The component is housed in a TQFP-64 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the revision history for any pinout or electrical characteristic updates before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and moderate speed is required. Compare the 625 kSPS rate against application bandwidth needs. Verify that the available 105 dB SNR meets system dynamic range requirements. Confirm compatibility with the required 2.7 V to 3.3 V digital logic levels and 5 V analog supply constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS1672 family of high-performance ADCs. It shares architectural similarities with other delta-sigma converters in the series but is distinguished by its specific 625 kSPS throughput and 24-bit resolution. The IPAG package denotes a plastic quad flatpack variant suitable for surface mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the official TI selection guide for direct functional equivalents within the ADS16xx series. Verify pin-to-pin compatibility if substituting with variants like the ADS1671 or ADS1673. Ensure replacement parts maintain the same TQFP-64 package dimensions and thermal characteristics.
