3 Description
The ADS127L11 is a 24-bit, delta-sigma (ΔΣ), analogto-
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 lowlatency
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.
