SG Micro SGM90516

The SGM90516 is a high integrated analog front end, which includes 16 monotonic 12-bit DACs, a 21-input 12-bit SAR ADC, a temperature sensor and an on-chip reference.

The chip also has 8-channel general purpose inputs and outputs (GPIOs). These pins are configurable for ADC inputs or GPIOs.

The chip is operated by a 4-wire SPI-compatible interface.

The SGM90516 is available in a Green TQFP-10×10-64L (Exposed Pad) package. It is specified from -40℃ to +125℃.
