Overview
The ADS127L01IPBSR, produced by Texas Instruments, is a 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) designed to offer a unique combination of excellent DC accuracy and outstanding AC performance. This device is capable of data rates up to 512 kSPS and features a high-order, chopper-stabilized modulator that achieves very low drift with low in-band noise. The integrated decimation filter suppresses modulator out-of-band noise, making it suitable for high-precision industrial measurements over an extended temperature range of –40°C to +125°C.
