MS5112M

MS5112M is a high-precision 16-bit ADC featuring 2 differential input channels or 3 single-ended input channels with up to 16-bit resolution. It integrates an internal 2.048V reference, with a differential input range of ±2.048V. The MS5112M uses an I²C-compatible interface with 2 address pins, allowing users to select from 8 I²C slave addresses. The supply voltage range is 2.7V to 5.5V. The MS5112M supports conversion rates of 15, 30, 60, or 240 SPS and integrates a programmable gain amplifier with a maximum gain of 8×. In single-shot conversion mode, the MS5112M automatically enters a power-saving state after conversion completes, reducing power consumption. The MS5112M is suitable for high-precision measurement applications where space and power consumption are critical considerations.
