ADS1259IPWR

Overview

The ADS1259IPWR is a low-noise, 24-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta architecture and features a single differential or pseudo-differential input channel with an integrated programmable gain amplifier (PGA). The device supports data rates up to 14.4 kSPS and operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply range of 2.7 V to 5.25 V. It communicates via an SPI interface and is housed in a 20-TSSOP package. Key performance metrics include an integral nonlinearity of 0.0003% FSR and a typical power consumption of 13 mW.

Feature Summary

• Integrated programmable gain amplifier allows direct measurement of small signals without external amplification.
• Built-in oscillator and 50/60 Hz rejection capabilities simplify filter design for industrial applications.
• Low drift internal reference buffer reduces the need for high-precision external components.

Applications

• Industrial process control systems requiring high-resolution sensor interfacing
• Weigh scales and force measurement instrumentation
• Medical equipment such as ECG and physiological signal monitoring

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component meets RoHS3 compliance standards if required by the target market regulations. Cross-reference the ordering number with official distributor catalogs to validate authenticity and avoid counterfeit risks during sourcing.

Selection Notes

Select this component when a single-channel, high-resolution conversion is necessary with minimal external circuitry. The integrated PGA and reference buffer reduce bill-of-materials complexity compared to discrete solutions. Consider the 20-TSSOP package constraints for PCB layout and thermal management within the specified operating temperature range of -40°C to +105°C.

Part Context

This part belongs to the ADS1259 family of precision data converters designed for field transmitters and sensors. It serves as a high-performance solution for applications demanding accurate analog signal digitization. The IPWR variant specifically denotes the industrial temperature range and TSSOP packaging format provided by Texas Instruments.

Replacement Considerations

Check for ADS1259IPW for tape-and-reel versus cut-tape variations. Verify compatibility with ADS1258 or ADS1256 if channel count or resolution differences are acceptable for the specific application design.
