The XTR300 is a complete output driver for industrial and process control applications. The output can be configured as current or voltage by the digital I/V select pin. No external shunt resistor is required. Only external gain-setting resistors and a loop compensation capacitor are required.
The separate driver and receiver channels provide flexibility. The Instrumentation Amplifier (IA) can be used for remote voltage sense or as a high-voltage, high-impedance measurement channel. In voltage output mode, a copy of the output current is provided, allowing calculation of load resistance.
The digital output selection capability, together with the error flags and monitor pins, make remote configuration and troubleshooting possible. Fault conditions on the output and on the IA input as well as over-temperature conditions are indicated by the error flags. The monitoring pins provide continuous feedback about load power or impedance. For additional protection, the maximum output current is limited and thermal protection is provided.
The XTR300 is specified over the −40°C to +85°C industrial temperature range and for supply voltages up to 40V.

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。
