ADS1225IRGVR

Overview

The ADS1225IRGVR is a single-channel, 24-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device supports sampling rates up to 100 S/s and features differential input types. Communication is handled via I2C or SPI interfaces. It is housed in a VQFN-16 package with a power consumption of 1.6 mW. Key performance metrics include a differential nonlinearity (DNL) of +/- 1 LSB and integral nonlinearity (INL) of 0.002% FSR. The component functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrated internal oscillator eliminates the need for external clock components.
• Built-in on-chip temperature sensor enables direct thermal monitoring.
• Supports both I2C and SPI serial communication protocols for flexible system integration.

Applications

• Precision industrial process control systems
• Portable battery-powered measurement devices
• High-resolution sensor signal conditioning

Procurement Notes

Verify the specific suffix IRGVR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and commercial grade temperature rating. Ensure compatibility with the target board's VQFN-16 footprint and soldering profile requirements before finalizing procurement orders.

Selection Notes

Select this component when high resolution is required at low data rates. The integrated oscillator and temperature sensor reduce external bill of materials. Verify that the system interface supports the selected I2C or SPI mode. Confirm that the 100 S/s maximum speed meets application timing constraints.

Part Context

This part belongs to the ADS1225 series of low-power, 24-bit ADCs. It shares architectural similarities with other members like the ADS1220 and ADS1221 but offers specific pinout and feature combinations tailored for compact designs. The IRGVR designation indicates a specific reel packaging variant for surface-mount assembly.

Replacement Considerations

ADS1225IRGVT: Identical electrical specifications with tray packaging instead of reel.
