DESCRIPTION

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 measurement, where space and power

consumption are major considerations. Typical applications

include portable instrumentation, industrial process control,

and smart transmitters.
