GENERAL DESCRIPTION

The SGM51613D, SGM51652D, and SGM51622D 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 differential input.

These chips have an on-chip high accuracy and low

drift 10ppm reference.

The digital interface is compatible to the traditional SPI

protocol.

The SGM51613D, SGM51652D, and SGM51622D are

available in Green TSSOP-16 and TQFN-4×4-16L

packages. They are all specified from -40℃ to +125℃.
