Description
General part information
ADS127L21 Series
The ADS127L21 is a 24-bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC) featuring a programmable digital filter. 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.
