SGM90508

8-Channel, 12-Bit, Configurable ADC/VDAC/IDAC

with On-Chip Reference, I²C Interface

GENERAL DESCRIPTION

FEATURES

The SGM90508 features 8 input/output (I/O) pins,

which can be independently configured as voltage

digital-to-analog converter (VDAC) outputs, current

digital-to-analog converter (IDAC) outputs, analog-

to-digital converter (ADC) inputs, digital outputs, or

digital inputs. When an I/O pin is configured as an

analog output, it is driven by a 12-bit VDAC. The VDAC

output range can be configured to 0V to V_REFor 0V to 2

× V_REF. When an I/O pin is configured as an ADC input,

it is an analog input to ADC by an analog multiplexer.

The ADC input range can be configured to V_REFor 2 ×

general-purpose input or output (GPIO) pins.

APPLICATIONS

The SGM90508 contains an integrated 2.5V, 11ppm/℃

(TYP) reference that is turned off by default. And the

chip has an on-chip temperature sensor, which can

read out the die temperature through an ADC read

sequence.
