Gravity: GP8512 1-Channel 15-Bit I2C DAC Module (0-2.5V/VCC)

The Gravity GP8512 is a single-channel digital-to-analogue converter module featuring 15-bit resolution and I2C connectivity. It provides accurate analogue voltage generation for makers, students, and engineers working on instrumentation, testing, or signal generation projects. It is an ideal add-on for microcontrollers lacking native DAC outputs or requiring higher resolution control.

High-resolution 15-bit conversion

The module provides 15-bit digital-to-analogue conversion to enable smooth and granular voltage adjustment. This level of resolution allows for precise stepping in analogue control applications.

Simple I2C interface

The converter communicates via a standard I2C interface, requiring minimal wiring to the host controller. This allows easy integration into existing multi-device setups without consuming analogue pins.

Selectable output voltage ranges

Users can select between an output range of 0 to 2.5V or 0 to VCC to accommodate different system requirements. This flexibility ensures compatibility with a broad variety of analogue circuits and inputs.

High 0.01% voltage accuracy

The GP8512 offers an output accuracy of 0.01%, providing reliable and repeatable voltage levels. This makes it well suited for calibration tasks, reference voltage generation, and precision control.
