Texas Instruments ADS127L11 24-Bit Delta-Sigma (ΔΣ) Analog-to-Digital Converter (ADC) has data rates up to 400kSPS using the wideband filter and up to 1067kSPS using the low-latency filter. The device offers excellent ac performance and dc precision with low power consumption (18.6mW 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 3mm × 3mm WQFN and 6.5mm × 4.4mm TSSOP packages are designed for limited space applications. The Texas Instruments ADS127L11 is fully specified for operation over the –40°C to +125°C temperature range.
