The Texas Instruments ADS1115IDGSR is a 16-bit delta-sigma analog-to-digital converter with an I2C interface, supplied in a 10-pin VSSOP package on tape and reel. It provides four inputs configurable as two differential channels, samples at up to 860 SPS with bipolar input polarity, and specifies 1 LSB integral nonlinearity. The single-supply device operates from 2 V to 5.5 V drawing 150 uA nominal supply current for 900 uW power dissipation. ADS1115IDGSR is a production-status, lead-free, RoHS-compliant device rated -40 C to +125 C.

A delta-sigma ADC oversamples its input and filters the result digitally, which trades conversion speed for resolution and noise performance, making it the standard choice for precision measurement rather than high-speed signal capture. With 16 bits at up to 860 SPS, differential inputs and an I2C bus that adds only two pins, the ADS1115IDGSR is used to give a microcontroller accurate measurement capability it lacks internally. Typical measurements include bridge and load-cell outputs, thermocouple and RTD temperature, 4-20 mA current-loop signals, battery voltage and current, and gas or pressure sensor front ends. Buyers are typically embedded and instrumentation designers in industrial monitoring, medical devices, environmental sensing, energy metering and test equipment.
