Overview
The ADS127L01IPBS from Texas Instruments is a 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) designed for high-speed and wide-bandwidth applications. This device offers a unique combination of excellent DC accuracy and outstanding AC performance. It features a high-order, chopper-stabilized modulator that achieves very low drift with low in-band noise, and an integrated decimation filter that suppresses modulator out-of-band noise. The ADS127L01IPBS operates over an extended industrial temperature range of –40°C to +125°C, making it suitable for a variety of industrial and precision measurement applications.
