The SGM51622S8 and SGM51652S8 are 16-bit, 8-channel simultaneous sampling, high-precision successive approximation (SAR) analog-to-digital converters (ADCs).
These ADCs are powered by a single unipolar 5V, and support true bipolar ±10V and ±5V inputs. The input range is configured by hardware pin.
These chips provide over-voltage protection up to ±20V at the input.
These chips have an on-chip high accuracy and low drift 8ppm/℃ reference.
The input impedance of these chips is 1MΩ and it is independent of the input range selection.
These ADCs support both high-speed serial and parallel interfaces.
The SGM51622S8 and SGM51652S8 are available in a Green LQFP-10×10-64L package. They are all specified from -40℃ to +125℃.
