ADS1110A7IDBVT

I/O接口16位A/D转换器

DESCRIPON

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.
