The OPA341 series rail-to-rail CMOS operational amplifiers are designed for low-cost, miniature applications. They are optimized for low-voltage, single-supply operation. Rail-to-rail input and output and high-speed operation make them ideal for driving sampling Analog-to-Digital (A/D) converters.

The power-saving shutdown feature makes the OPA341 ideal for portable low-power applications. The OPA341 series is also well suited for general-purpose and audio applications as well as providing I/V conversion at the output of Digital-to-Analog (D/A) converters. Single and dual versions have identical specifications for design flexibility.

The OPA341 series operate on a single supply as low as 2.5V, and input common-mode voltage range extends 300mV beyond the supply rails. Output voltage swings to within 1mV of the supply rails with a 100k load. The OPA341 series offers excellent dynamic response (BW = 5.5MHz, SR = 6V/us) with a quiescent current of only 750uA. The dual design features completely independent circuitry for lowest crosstalk and free-dom from interaction.

The single (OPA341) packages are the tiny SOT23-6 surface mount and SO-8 surface mount. The dual (OPA2341) comes in the miniature MSOP-10 surface mount. All are specified from \x9655°C to +125°C and operate from \x9655°C to +150°C. The OPA343 provides similar performance without shut-down capability.

CIRCUIT060013 — 具有 T 網路回饋電路的反相放大器

此設計可反轉輸入訊號 VIN，並使用 1000 V/V 或 60 dB 訊號增益。具有 T 回饋網路的反相放大器可在沒有較小 R4 值或超大回饋電阻器值的情況下獲得高增益。

CIRCUIT060074 — 具有比較器電路的高壓側電流感測

此高壓側電流感測解決方案使用一個具有軌對軌輸入共模範圍的比較器，若負載電流上升到 1 A 以上，便在比較器輸出 (COMP OUT) 建立過電流警示 (OC 警示) 訊號。此實作中的 OC 訊號為低電位作動。因此當超過 1-A 閾值時，比較器輸出會變低。實作磁滯後會在負載電流降低至 0.5 A (減少 50%) 時，讓 OC-Alert 返回邏輯高狀態。此電路利用開漏輸出比較器，為控制數位邏輯輸入針腳而進行電平轉換輸出高邏輯電平。對於需要驅動 MOSFET 開關閘極的應用，建議使用具推挽輸出的比較器。
