The ADS1110 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with differential inputs and up to 16 bits of resolution in a small SOT23-6 package. The onboard 2.048V reference provides an input range of ±2.048V differentially. The ADS1110 uses an I2C-compatible serial interface and operates from a single power supply ranging from 2.7V to 5.5V. The ADS1110 can perform conversions at rates of 15, 30, 60, or 240 samples per second. The onboard programmable gain amplifier (PGA), which offers gains of up to 8, allows smaller signals to be measured with high resolution. In single-conversion mode, the ADS1110 automatically powers down after a conversion, greatly reducing current consumption during idle periods. The ADS1110 is designed for applications requiring high resolution.
The ADS1110 is a fully differential, self-calibrating delta-sigma A/D converter designed for high-resolution measurements in space-constrained applications. It features an onboard 2.048V voltage reference and a programmable gain amplifier (PGA) with gains up to 8x.
