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.
