Product details

12-bit sigma-delta ADC with I2C and PGA

The Texas Instruments ADS1015IDGST is a 12-bit sigma-delta ADC with a built-in programmable gain amplifier (PGA) and an I2C interface.

Input flexibility and address selection

The MUX-PGA-ADC architecture supports two differential or four single-ended inputs, configurable through the I2C interface. The selectable address feature allows up to four ADS1015 devices on the same I2C bus, enabling multi-channel sensor arrays without additional GPIOs.

The 10-VSSOP package (3.00 mm width) fits space-constrained PCBs and is surface-mount for automated assembly.

Frequently asked questions

What is the resolution of the ADS1015IDGST?

It is a 12-bit ADC, providing 4096 discrete output codes over the selected input range. The PGA amplifies small sensor signals before conversion, effectively increasing the usable dynamic range.

Does the ADS1015IDGST require an external reference?

No. It has an internal reference, so no external voltage reference IC is needed. This simplifies the BOM and reduces board area.
