Overview
The ADS1262IPWR is a 32-bit delta-sigma analog-to-digital converter manufactured by Texas Instruments, housed in a 28-TSSOP surface-mount package. It features an integrated multiplexer, programmable gain amplifier, and ADC with a maximum sampling rate of 38 kSPS. The device supports 11 differential or single-ended inputs and includes internal and external reference options. Power supplies operate at 4.75V to 5.25V for analog circuits and 2.7V to 5.25V for digital logic. It offers SPI interface communication, built-in temperature sensing, and fault detection capabilities within an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrated MUX-PGA-ADC architecture supporting multiple input configurations
- Built-in excitation current sources (iDACs) for sensor biasing
- On-chip oscillator and GPIO pins for system flexibility
- High noise rejection capabilities for industrial environments
Applications
- Programmable logic controllers
- Industrial automation equipment
- Sensor measurement applications
Procurement Notes
Verify the specific suffix IPWR confirms the TSSOP-28 package and tape-and-reel packaging format. Confirm RoHS3 compliance and moisture sensitivity level 2 requirements during storage and handling. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.
Selection Notes
Select this component when high-resolution 32-bit data conversion is required alongside integrated signal conditioning. Consider the 38 kSPS speed limit and 11-input multiplexing capability against system throughput needs. Evaluate power supply constraints given the separate analog and digital voltage ranges specified in the datasheet.
Part Context
This device belongs to the ADS126x family of precision delta-sigma ADCs designed for demanding industrial applications. It shares architectural similarities with the ADS1263 but differs in input channel count and configuration. The IPWR suffix specifically denotes the plastic small-outline package variant suitable for automated surface-mount assembly processes.
Replacement Considerations
The ADS1263 is a related device within the same family offering different input configurations. Verify pin compatibility and functional equivalence before substitution. No other direct cross-model replacements are confirmed in public documentation.
