ADS1112IDGSR

The ADS1112IDGSR is a precision 16-bit analog-to-digital converter (ADC) from Texas Instruments. It integrates a delta-sigma modulator, programmable gain amplifier (PGA), internal voltage reference, and oscillator in a compact 10-VSSOP package. The device supports up to 3 single-ended or 2 differential input channels with a maximum sampling rate of 240 SPS. It communicates via I2C interface with eight selectable addresses. Key specifications include a typical power consumption of 0.675 mW, supply voltage range of 2.7 V to 5.5 V, and an operating temperature range of -40°C to 85°C. The ADC features continuous self-calibration, single-cycle conversion, and programmable data rates from 15 SPS to 240 SPS. Its integral nonlinearity is 0.01% of FSR maximum. The internal reference provides 2.048 V with 5 ppm/°C drift. The device is suitable for portable instrumentation, industrial process control, smart transmitters, consumer goods, factory automation, and temperature measurement applications. It is available in a surface-mount 10-VSSOP package.
