3 Description

The ADC810-Q1 is an I/O expander device that includes a 12-bit, I2C-compatible, analog-to-digital converter (ADC) and provides 8-bits of general-purpose parallel input/output offered in a SOT-16 package. The ADC810-Q1 incorporates an internal voltage reference and an oscillator. The ADC810-Q1 also incorporates a programmable internal voltage reference and a digital comparator. These features, along with a wide operating supply range, are useful for power- and space-constrained, sensor measurement applications.

The device performs conversions at data rates up to 3300 samples per second (SPS). The VREF offers values of 1.4V, 2.5V, and VDD. The ADC810-Q1 features an input multiplexer (MUX) that allows eight single-ended input measurements. The digital comparator in the AC810 can be used for under- and overvoltage detection.

The ADC810-Q1 operates in either continuous-conversion mode or single-shot mode. Data are transferred through an I2C-compatible serial interface.
