SG Micro SGM5200Q

The SGM5200Q is a 12-bit, multi-channel input, successive approximation (SAR) analog-to-digital converter (ADC).

The input signal is sampled on the nCS falling edge. The ADC conversion is droved by external clock SCLK.

The SGM5200Q supports manual channel selection and two kinds of auto channel scan modes. The input range of SGM5200Q is software configurable, 0V to reference voltage or 0V to two times of reference voltage. It also supports two programmable alarm thresholds for each channel. The SGM5200Q provides power-down mode.

The SGM5200Q is AEC-Q100 qualified and is suitable for automotive applications.
