Automotive-grade 12-bit ADC with PGA and I²C
It integrates a multiplexer (MUX) and a programmable gain amplifier (PGA) ahead of the converter, so small differential or single-ended signals from thermocouples, shunt resistors, or pressure sensors can be digitised without an external op-amp stage.
3.3 kSPS throughput and supply flexibility
The ADC samples at 3.3 kSPS — adequate for low-bandwidth sensor monitoring, battery-voltage logging, or temperature readback in an automotive ECU. The single supply range from 2V to 5.5V covers both 3.3V and 5V digital domains without a separate analog rail, and the internal reference eliminates an external reference IC. Two or four input channels (configured as differential pairs or single-ended) are selected through the I²C interface, which also carries the conversion result and configuration register writes. The 0:1 S/H-to-ADC ratio confirms a continuous-conversion architecture — no sample-and-hold overhead.
Temperature range and package for automotive environments
Rated for -40°C to 124°C operating temperature, the ADS1015BQDGSRQ1 exceeds the standard industrial 105°C ceiling, suiting it for engine-bay, transmission, or exhaust-adjacent sensor boards. The 10-VSSOP package (3.00 mm width) is a compact surface-mount footprint that fits space-constrained ECU layouts.
