SGM51652H
16-Bit, High-Speed, Programmable Bipolar Input Ranges, SAR ADC
The SGM51613H, SGM51652H, and SGM51622H are a series of 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 at input, which is up to ±20V.
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 the input range selection.
The digital interface is compatible to the traditional SPI protocol.
The SGM51613H, SGM51652H, and SGM51622H are available in Green TSSOP-16 and TQFN-4×4-16L packages. They are all specified from -40℃ to +125℃.
