The SGM52412RG is a 24-bit, low-noise, 16 channels, sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The multiplexer supports 8 differential inputs or 16 single-ended inputs configuration. When used with a 5V reference, the input range can be a unipolar range of 5V or true bipolar range of ±2.5V.
The SGM52412RG contains the internal system monitor registers that provide supply voltage monitor, temperature sensor monitor, external reference voltage monitor, and input offset monitor. It has an SPI-compatible interface.
The SGM52412RG has the on-chip configurable current sources that can be used to bias external sensors or verify sensor integrity.
The SGM52412RG operates from a unipolar +5V or bipolar ±2.5V analog supply and a digital supply range from 2.7V to 5.25V.
The SGM52412RG is available in a Green TQFN-7×7-48AL package. It is specified from -40℃ to +125℃.
