GENERAL DEscriptION

The SGM5200 is a 12-bit, multi-channel input, successive approximation (SAR) analog-to-digital converter (ADC).

The SGM5200 analog power supply range is 2.7V to 5.25V. The SGM5200 has an SPI-compatible interface that digital power supply range is 1.7V to 5.25V.

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

The SGM5200 supports manual channel selection and two kinds of auto channel scan modes.

The input range of SGM5200 is software configurable, 0 to reference voltage or 0 to two times of reference voltage. It also supports two programmable alarm thresholds for each channel.

The SGM5200 provides power-down mode.

The SGM5200 is available in Green TSSOP-38 and TQFN-5×5-32L packages. It operates over an ambient temperature range -40℃ to +125℃.
