3 Description
The ADS127L21 is a 24-bit, delta-sigma (ΔΣ), analogto-
digital converter (ADC) featuring a programmable
digital filter with data rates up to 512 kSPS using
the wideband filter and up to 1365 kSPS 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 3-mm × 3-mm WQFN package is designed
for space-limited applications. The device is fully
specified for operation over the –40°C to +125°C
temperature range.
