The ADS1112 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with two differential or three single-ended channels and up to 16 bits of resolution. It is available in MSOP-10 and leadless QFN packages and is suitable for applications such as portable instrumentation, industrial process control, smart transmitters, consumer goods, factory automation, and temperature measurement.
The ADS1112 is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter featuring two differential or three single-ended channels with up to 16 bits of resolution. It is available in small MSOP-10 and leadless QFN-style packages and includes an onboard 2.048V reference and programmable gain amplifier (PGA). The device uses an I2C-compatible serial interface with two address pins allowing selection of one of eight I2C Slave addresses.
