- ADS127L21 — 24-bit, 512-kSPS wide-bandwidth delta-sigma ADC with programmable IIR and FIR filters
The ADS127L21 is a 24-bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC) featuring programmable digital filters. This digital filter has data rates up to 512kSPS using the wideband filter and up to 1365kSPS using the low-latency filter. The device offers an excellent combination of ac performance and dc precision with low power consumption.
Programmable infinite and finite impulse response (IIR and FIR) digital filters allow custom filter profiles, such as A-weighting compensation and frequency notch filters. The wideband or low-latency filter option optimize ac-signal performance or data throughput of dc signals, all in one device.
The low-drift modulator achieves excellent dc precision with low wideband noise for outstanding ac performance. The power-scalable architecture features four speed modes to optimize data rate, resolution, and power consumption. Signal and reference input buffers reduce driver loading for increased accuracy.
The serial interface features daisy-chain capability to reduce the number of signal lines over an isolation barrier. SPI input data and register memory contents are validated by cyclic-redundancy check (CRC) to enhance operational reliability.
The small 3mm × 3mm WQFN package is designed for space-limited applications. The device is fully specified for operation over the –40°C to +125°C temperature range.
