Overview

The SIG7190 is a low noise, low drift, and high-resolution 24-bit analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA) that offers high-accuracy measurement solutions for bridge sensors, thermocouples, and resistance temperature devices (RTD). The device contains a low noise PGA with gains selected from 1, 2, 4, 8 16, 32, 64, and 128, a delta-sigma (Δ - Σ) modulator, and a programmable digital SINC4/SINC3/fast settling filter. 50Hz/60Hz simultaneous rejection option is also provided. The output data rate from the device can be configured from 4.7SPS up to 4800SPS. This device provides channel sequencer feature to measure two differential inputs or four pseudo differential inputs automatically. Burnout current sources are provided at the analog inputs for sensor connection diagnosis. Offset and gain calibration registers are provided with calibration command or direct register write to calibrate the ADC errors or overall system errors. SPI-compatible interface is used for device configuration and parity check is provided for data integrity. The on-chip oscillator, an external clock, or an external crystal can be used as the clock source to the device. The device can operate with bipolar ±1.35V to ±2.625V analog power supplies, or with a single 2.7V to 5.25V analog power supply. The SIG7190 is available in 24-lead TSSOP package and is fully specified over the -40°C to +125°C temperature range.
