The ADS1100 is a 16-bit analog-to-digital converter (ADC) from Texas Instruments that features differential inputs, a programmable gain amplifier, and a single-cycle conversion.
The ADS1100 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with differential inputs and up to 16 bits of resolution. It operates from a single power supply ranging from 2.7V to 5.5V and uses an I2C-compatible serial interface for communication.
The device features a programmable gain amplifier with gains of 1, 2, 4, or 8, allowing it to measure small signals with high resolution. It includes continuous self-calibration to compensate for offset and gain errors, ensuring accuracy across its operating temperature range of -40°C to +85°C.
