ADS1271IPWR

Analog To Digital Converters (ADC) Overview

The ADS1271IPWR is a single-channel, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 105 kS/s and features a differential input type. The device utilizes an SPI interface for digital communication. Power requirements include an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 1.65 V to 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 109 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of +/- 0.0015% FSR. It functions within a temperature range of -40°C to +105°C and is housed in a TSSOP-16 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR indicates the reel packaging variant distinct from the tube-packaged IPW version. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the external reference voltage matches the required 2.5 V specification for optimal performance alignment with datasheet parameters.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC with wide bandwidth is required. Compare against other ADS127x family members if multiple channels are needed. Verify that the SPI interface timing aligns with the host microcontroller capabilities. Consider the TSSOP-16 footprint constraints during PCB layout planning.

Analog To Digital Converters (ADC) Part Context

The ADS1271 belongs to the ADS1271 series of industrial-grade delta-sigma ADCs. It serves as the foundational single-channel architecture for higher-channel variants such as the ADS1274 and ADS1278. This part number specifically denotes the tape-and-reel packaging format intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1271IBPW is a verified alternative within the same series offering identical electrical specifications but utilizing tube packaging instead of reels.
