ADS1262IPW

Overview

The ADS1262IPW is a 32-bit analog-to-digital converter manufactured by Texas Instruments, housed in a 28-TSSOP surface-mount package. It utilizes a sigma-delta architecture with an integrated multiplexer, programmable gain amplifier, and ADC. The device supports up to 11 differential or single-ended input channels and achieves a sampling rate of 38 kSPS. It operates on an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. Key features include an internal reference, temperature sensor, and GPIO capabilities. The component functions within a wide operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-resolution 32-bit delta-sigma ADC with a built-in multiplexer and programmable gain amplifier for signal conditioning.
• Includes an internal voltage reference and dedicated excitation current sources (iDACs) to support direct sensor interfacing.
• Features a comprehensive interface register set allowing configuration of conversion modes, filter settings, and status monitoring via SPI.

Applications

• Industrial process control systems requiring high-precision data acquisition
• Weigh scales and load cell measurement applications
• Medical instrumentation and patient monitoring devices

Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-28 tube packaging variant rather than the 'IPWR' tape-and-reel version. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the ordering quantity matches the standard factory tube pack size of 50 units to avoid partial reel issues.

Selection Notes

Select this model when a 32-bit resolution and 38 kSPS throughput are required alongside multiple input channels. Compare against the ADS1263 if additional TDAC outputs are needed for sensor excitation. Verify that the 2.7 V minimum digital supply voltage aligns with the system logic levels, as lower voltage options exist in other series members.

Part Context

This component belongs to the ADS126x family of precision ADCs designed for demanding industrial environments. It shares architectural similarities with the ADS1263 but differs in channel count and output capabilities. The IPW designation specifically identifies the non-reel tube packaging format used for prototyping and low-volume manufacturing.

Replacement Considerations

The ADS1263 serves as a functional substitute offering similar performance with added TDAC outputs. For pin-compatible alternatives with different packaging, verify the ADS1262IPWR variant which maintains identical electrical specifications while utilizing tape-and-reel delivery.
