The OPA2675 provides the high output current and low distortion required for power-line modem driver and test and measurement applications. The OPA2675 operates on power-supplies ranging from 4.5 V to 13 V and consumes a low 16.5 mA/channel quiescent current to deliver a very high 1000 mA output current. The OPA2675 supports the most demanding power-line modem requirements with an 850 mA specified minimum output current drive (at 25°C).

Power-control features are included to minimize system power consumption. Two logic-control lines allow for four quiescent power settings, full power, 75% bias power, 50% bias power, and offline mode with active offline control, to provide high impedance to large signals present at the output pin. The two channels of the OPA2675 can be used independently as individual op amps, or can be configured as a differential-input to differential-output, high-current line driver.

DEM-OPA-RGV-EVM — 用於採用 VQFN 封裝的高速高輸出電流放大器的空板評估模組

DEM-OPA-RGV-EVM 是一個空板的評估模組 (EVM)，用於我們的採用 VQFN (RGV) 封裝的雙寬頻運算放大器。本 EVM 是根據高速性能規格及電源線通訊 (PLC) 和傳輸線驅動器來設計。EVM 的設計可讓我們使用實驗室設備的 50-Ω SMA 接頭的高速雙放大器，進行快速有效率的實驗室測試。EVM 可以針對不同增益及單一或分裂電源運作，進行輕鬆配置。兩個通道可當成獨立放大器使用，或可設為差動輸入至差動輸出驅動器。適當電阻器的變壓器可在輸出時當成 50-Ω 單端輸出使用。
