Texas Instruments ADS127L21B Wideband Delta-Sigma Analog-to-Digital Converter (ADC) is a high-precision, 24-bit, delta-sigma (ΔΣ) ADC featuring programmable digital filters. The digital filter has data rates up to 512kSPS using the wideband filter and up to 1365kSPS using the low-latency filter. The device offers excellent AC performance and DC precision with low power consumption. The low-drift modulator achieves excellent DC precision with a maximum of 0.8ppm INL (0°C to 70°C) and outstanding AC performance with low wideband noise. The power-scalable architecture features four-speed modes to optimize resolution, data rate, and power consumption. Signal and reference input buffers reduce driver loading for increased accuracy.
