The DAC756x, DAC816x, and DAC856x devices are low-power, voltage-output, dual-channel, 16-, 14-, and 12-bit digital-to-analog converters (DACs), respectively. These devices include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA at the VREFIN/VREFOUT pin.
These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three-wire serial interface that operates at clock rates up to 50 MHz. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces. The DACxx62 devices incorporate a power-on-reset circuit that ensures the DAC output powers up and remains at zero scale until a valid code is written to the device, whereas the DACxx63 devices similarly power up at mid-scale. These devices contain a power-down feature that reduces current consumption to typically 550 nA at 5 V. The low power consumption, internal reference, and small footprint make these devices ideal for portable, battery-operated equipment.
The DACxx62 devices are drop-in and function-compatible with each other, as are the DACxx63 devices. The entire family is available in MSOP-10 and SON-10 packages.

TIDA-00454 — 具有隔離式 DC 類比輸出的三相 AC 電壓和電流轉換器參考設計
此參考設計採用 MSP430F67791A 裝置來精確測量電壓和電流。它還示範如何使用兩個 DC 類比輸出通道，這兩個通道可以分別配置為電壓輸出 (±10V) 或電流輸出 (±24mA)。這種設計的優點在於它可以測量電壓和電流，並提供與 AC 輸入成比例的 DC 類比輸出。另一個優點是雙向 DC 類比輸出。
該設計具有六個數位輸出，可用於驅動繼電器。此設計的功能可以擴展到測量功率。
TIPD155 — 雙通道源極/汲極組合電壓和電流輸出、隔離、EMC/EMI 測試參考設計
這款 TI 認證參考設計實作雙通道電壓與電流組合類比輸出模組。這兩個輸出是獨立的，可在標準工業輸出範圍內提供和汲極電壓與電流。 此設計具備 ±10 V 與 ±24 mA 輸出的特性，透過調整外部電阻值，輸出範圍可達 0-5 V、0-10 V、±5 V、±10 V.4-20 mA、0-20 mA、0-24 mA、±20 mA、±24 mA。
此設計包括通過 IEC61000-4-2/3/4/5/6 測試所需的外部保護元件，以及測量的測試資料。 保護電路不會對設計造成負面影響，測試結果顯示典型的未調整誤差為全刻度範圍 (FSR) 的 0.1% ，校準誤差低於 0.01% FSR。
