ADS1672IPAGR

Analog To Digital Converters (ADC) Overview

The ADS1672IPAGR 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: 4.75 V to 5.25 V for the analog section and 2.7 V to 3.3 V for the digital interface. Key performance metrics include a signal-to-noise ratio (SNR) of 105 dB, integral nonlinearity (INL) of 9.5 ppm, and differential nonlinearity (DNL) of +/- 1 LSB. It features an LVDS serial output interface and consumes approximately 350 mW of power. The component is housed in a TQFP-64 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-resolution 24-bit delta-sigma conversion architecture
• Low noise performance with 105 dB SNR at 625 kSPS
• LVDS serial output interface for high-speed data transfer
• Dual voltage supply operation for analog and digital sections

Analog To Digital Converters (ADC) Applications

• Medical imaging systems requiring high precision
• Industrial process control and monitoring
• Seismic data acquisition equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GR' indicates tape and reel packaging when ordering. Confirm that the required external reference voltage matches the device's specifications. Ensure the design accommodates the TQFP-64 thermal requirements and LVDS termination resistors for signal integrity. Check for RoHS compliance status relevant to the manufacturing date code.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 24-bit ADC is required. Compare against the ADS1672IPAG if bulk tray packaging is preferred over tape and reel. Consider lower speed variants like the ADS1675 if higher throughput is not necessary. Verify compatibility with existing microcontroller SPI interfaces despite the LVDS output requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1672 series of high-performance sigma-delta ADCs. It shares architectural similarities with other TI precision converters but is distinguished by its specific 625 kSPS speed and 24-bit resolution combination. The IPAGR suffix denotes the industrial grade version in tape and reel format, differing from the standard IPAG tray package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1672IPAG is a direct pin-compatible alternative offering identical electrical characteristics but in a tray package. Other ADS167x family members may require schematic modifications due to different pinouts or performance trade-offs.
