The SGM51652H4 and SGM51652H8 are 4-channel and 8-channel, 16-bit resolution, high-precision successive approximation (SAR) analog-to-digital converters (ADCs).
These ADCs are powered by a single unipolar 5V, and support true bipolar ±10.24V, ±5.12V, and ±2.56V inputs, as well as unipolar input ranges of 0V to 10.24V and 0V to 5.12V. The input range is configured by software.
These chips provide over-voltage protection up to ±20V at the input.
These chips have an on-chip high accuracy and low drift 10ppm reference.
The input impedance of these chips is ~1MΩ and it is independent of input range selection.
The digital interface is compatible to the traditional SPI protocol.
