High-precision analog-to-digital conversion chip - MS1112

MS1112 is a high-precision, continuously converting self-calibrating analog-to-digital converter with2 differential input or 3 single-ended input channels, with conversion accuracy up to 16 bits.The internally integrated 2.048V reference source makes the differential input range reach ±2.048V.It uses I2C-compatible interface, and has 2 address pins, allowing users to select eightI2C slave addresses. The power supply voltage range is 2.7V to 5.5V.MS1112 conversion rate is 15, 30, 60 or 240SPS, with integrated programmablegain amplifier, with a gain up to 8 times, which can also ensure accuracyto measure small signals. In single conversion mode, MS1112 turns off after the conversion endsconversion, reducing power consumption in idle state.MS1112 is used in applications requiring high-precision measurement and having certain requirements for space and power consumptionapplications, typical applications such as: handheld instruments, industrial process control and smart transmitterstransmitter.
