The XTR305 is a complete output driver for cost-sensitive 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, makes remote configuration and troubleshooting possible. Fault conditions on the output and on the IA input, as well as overtemperature 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 XTR305 is specified over the −40°C to +85°C industrial temperature range and for supply voltages up to 40 V, and is operational over the extended industrial temperature range (−55°C to +125°C).

TIDA-01633 — 適用於 AC/伺服驅動器的精巧型可編程 4-20mA 和 +/-10V 類比輸出參考設計

此參考設計實現精巧體積、雙通道可配置類比電壓及電流輸出模組，適合 AC 逆變器與伺服驅動器使用。整合式工業輸出驅動器：與使用多個運算放大器及被動元件時的狀況相比，XTR305 的尺寸更為精巧。輸出可透過主機 MCU（如 C2000™ MCU）編程為 ± 10V 或 4mA 至 20mA，或使用跨接器手動配置。錯誤旗標與輸出負載監控功能可實現穩固設計。同一通道還可配置為 ± 10V 或 4mA 至 20mA 的類比輸入。介面適合 C2000 LaunchPad™ 開發套件。
