DESCRIPTION
The SGM5208-14 and SGM5209-14 are 14-bit, high-precision, multi-channel input, successive approximation (SAR) analog-to-digital converters (ADCs).
The SGM5208-14 supports 8 single-ended inputs. The SGM5209-14 supports 4 single-ended inputs. The SGM5208-14 and SGM5209-14 need to work with an external voltage reference. Its available range is 1.2V to 4.2V. The digital interface is compatible to the traditional SPI protocol.
The SGM5208-14 and SGM5209-14 are available in Green TQFN-4×4-24L and TSSOP-24 packages. It operates over an ambient temperature range -40℃ to +125℃.
