Boardoza TPC2161 16-Bit Bipolar DAC Breakout Board
Boardoza TPC2161 is a 16-Bit Digital to Analog Converter Breakout Board based on the TPC2161 DAC , dual polarity LDO regulator , and voltage reference IC. It allows microcontrollers (Arduino, STM32, ESP32, Raspberry Pi, etc.) to generate highly precise analog voltage outputs via a simple 3-wire SPI interface. The module is widely used in industrial automation, medical instrumentation, wave generators, and precision bias voltage control. Additionally, the onboard output buffer op-amp provides low-impedance rail-to-rail driving capability for the analog output signal (-2,5V to +2,5V). With the Boardoza TPC2161 module, you can easily implement ultra-low-noise, bipolar or unipolar precise voltage control loops without the need for complex external dual-rail power setups or external analog buffer circuits.

Key Features
- High-Precision 16-Bit Resolution: Delivers ultra-fine, micro-volt level steps for clean analog output wave generation.
- Onboard Dual Polarity Power Subsystem: Integrated LDO generates symmetrical supply voltage for buffer.
- Buffered Analog Output: Employs a high-speed, rail-to-rail operational amplifier to minimize output impedance and increase drive current capacity.
- Standard 3-Wire SPI Interface: Standard SCLK, SDI, and Chip Select (CS) lines ensure immediate software library compatibility.
