Texas Instruments ADS1018QDGSRQ1 12-bit ADC 4-ch SPI Temp Sensor

Description

The TI ADS1018-Q1 is an automotive-grade 12-bit analog-to-digital converter (ADC) with an integrated temperature sensor. It features four channels and communicates via SPI interface. The device is supplied in a VSSOP-10 package and is qualified for automotive applications.

This ADC operates from a supply voltage of 2 V to 5.5 V. It integrates a programmable gain amplifier, a voltage reference, an oscillator, and a temperature sensor. The programmable gain amplifier supports input ranges from plus or minus 256 mV to plus or minus 6.144 V. The device offers a maximum conversion rate of 3300 samples per second.

An internal multiplexer allows for selection between two differential or four single-ended inputs. The integrated temperature sensor provides functionality for system monitoring or cold-junction compensation. The device supports both continuous-conversion mode and single-shot mode for power savings. It operates across a temperature range of minus 40 degrees Celsius to plus 125 degrees Celsius. The part number is ADS1018QDGSRQ1.
