The ADS1258IRTCR is a precision 24-bit, 125kSPS delta-sigma analog-to-digital converter from Texas Instruments. It integrates a 16-channel multiplexer that can be configured as 16 single-ended or 8 differential inputs, supporting both unipolar (0 to 5.35V) and bipolar (±2.85V) input voltage ranges. The device uses an SPI interface and operates from a 4.75V to 5.25V analog supply and a 2.7V to 5.25V digital supply, with typical power consumption of 42mW.
Key performance features include integral nonlinearity of 0.0003%, low noise of 2.8 µV RMS at 1.8kSPS, and excellent DC stability with offset drift of 0.02 µV/°C and gain drift of 0.4 ppm/°C. The ADC offers fixed-channel sampling at 125kSPS and automatic channel scanning at 23.7kSPS per channel, with single-conversion settled data. Additional capabilities include open-sensor detection, conversion control pin, multiplexer output for external signal conditioning, and on-chip readback of temperature, reference, offset, gain, and supply voltage.
The ADS1258IRTCR is housed in a 48-VFQFN Exposed Pad package (48-VQFN 7x7) for surface-mount assembly. It is rated for industrial temperature range of -40°C to 105°C. Typical applications include medical instrumentation, avionics, process control, machine and system monitoring, and fast-scan multi-channel data acquisition systems.
