ADS1259BIPWR

Overview

The ADS1259BIPWR is a low-noise, industrial-grade 24-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta architecture to achieve high precision with a maximum sampling rate of 14.4 kSPS. The device features a single differential input channel and integrates a programmable gain amplifier (PGA) with gains ranging from 1 to 128. It operates with an analog supply voltage between 4.75 V and 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. The component supports SPI interface communication and includes internal oscillator capabilities. It is housed in a 20-pin TSSOP package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a low-drift reference voltage source and buffer for simplified system design.
• Provides built-in 50 Hz and 60 Hz rejection filters to suppress power line interference.
• Supports both external and internal reference voltage configurations.

Applications

• Industrial process control systems requiring high-precision sensor measurements.
• Portable instrumentation devices powered by battery sources.
• Medical instruments such as electrocardiogram (ECG) and electroencephalogram (EEG) front ends.

Procurement Notes

Verify the specific suffix IPWR indicates tape-and-reel packaging when sourcing components. Confirm that the B-grade designation aligns with industrial temperature requirements for the target application environment. Ensure compatibility with the host microcontroller's SPI protocol settings before finalizing procurement orders.

Selection Notes

Select this component when applications demand 24-bit resolution with low noise performance at speeds up to 14.4 kSPS. Consider the integrated PGA if signal conditioning amplification is needed to boost small sensor outputs. Evaluate the power consumption constraints against the specified operating voltages to ensure efficient system energy management.

Part Context

This part belongs to the ADS1259 series of high-performance data converters. It shares architectural similarities with other members like the ADS1259IPW but differs in packaging format. The series is designed for applications requiring precise analog-to-digital conversion with minimal external component count.

Replacement Considerations

The ADS1259IPW serves as a tube-packaged alternative within the same functional family. Verify pinout compatibility and electrical specifications before substituting. Other series members may offer different channel counts or speed variations.
