Boardoza TPC2190 8-Channel 16-Bit DAC Breakout Board
Boardoza TPC2190 BRK is a compact breakout board built around the 3Peak TPC2190 8-channel, 16-bit Digital-to-Analog Converter (DAC) integrated circuit. The module delivers a rapid 6 µs output settling time and supports high-speed 4-wire SPI communication up to 20 MHz (SDI, SDO/ALRM, SCLK, nCS). Voltage reference selection is flexible: it can utilize the chip's integrated low-drift 2.5V internal reference or accept an external reference voltage from the REF pin, with software-configurable full-scale output gain options of 1/2, 1, or 2. The board features a digital I/O voltage rail (VIO) that is connected to VDD over JP1 by default. Opening JP1 separates VIO from VDD voltage, allowing it to be driven by an independent power rail (1.7V \~5.5V). The Boardoza TPC2190 BRK is widely used in industrial automation, optical networking, data acquisition systems, multi-channel sensor calibration, and automated test equipment (ATE).

Key Features
- SPI Communication: 4-wire SPI bus interface (SDI, SDO/nALRM, SCLK, nCS).
- 8 Channels Output : 8 independent DAC voltage output pins (Ch0 \~Ch7).
- Refresh Rate: Up to 833 kSample/s
- Configurable Reference: Dedicated REF pin can be configured for setting the DAC output voltage range.
- Flexible Logic Supply: VIO pin allows coniguring different I/O logic levels (1.7V \~5.5V).
