DESCRIPTION

The SGM5200 is a 12-bit multichannel inputs analog-to-digital converter (ADC). The device includes a capacitor based SAR ADC with inherent sample and hold circuit.

The SGM5200 accepts a wide power supply range from 2.7V to 5.25V. Very low power consumption makes the device suitable for battery-powered or isolated power supply applications.

A wide 1.7V to 5.25V digital I/O power supply range facilitates a glueless interface with the most commonly used digital hosts. The serial interface is controlled by nCS and SCLK for easy connection with microprocessors and DSP.

The input signal is sampled with the falling edge of nCS. 

It uses SCLK for conversion, serial data output and reading serial data in. The device allows auto sequencing of preselected channels or manual selection of a channel for the next conversion cycle.

There are two software selectable input ranges (0V to VREF and 0V to 2 × VREF), individually configurable GPIOs (four in case of the TSSOP package and one in TQFN package) and two programmable alarm thresholds per channel. These features make the device suitable for most data acquisition applications.

The SGM5200 offers an attractive power-down feature. This is extremely useful for power saving when the device is operated at lower conversion speeds.

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