The ADS127L11 is a 24-bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC)
with data rates up to 400 kSPS using the wideband filter and up to 1067 kSPS using
the low-latency filter. The device offers an excellent combination of ac performance
and dc precision with low power consumption (18.6 mW in high-speed mode).
The device integrates input and
reference buffers to reduce signal loading. The low-drift modulator achieves
excellent dc precision with low in-band noise for outstanding ac performance. The
power-scalable architecture provides two speed modes to optimize data rate,
resolution, and power consumption.
The digital filter is configurable for
wideband or low-latency operation, allowing wideband ac performance or data
throughput for dc signals to be optimized, all in one device.
The serial interface features
daisy-chain capability to reduce the SPI I/O over an isolation barrier. Input and
output data and register settings are validated by a cyclic-redundancy check (CRC)
feature to enhance operational reliability.
The small 3-mm × 3-mm WQFN and 6.5-mm
× 4.4-mm TSSOP packages are designed for limited space applications. The device is
fully specified for operation over the –40°C to +125°C temperature range.
