The OPAx316 family of single, dual, and quad operational amplifiers represents a new generation of general-purpose, low-power operational amplifiers. Featuring rail-to-rail input and output swings, low quiescent current (400 µA/ch typical) combined with a wide bandwidth of 10 MHz and very-low noise (11 nV/√Hz at 1 kHz) makes this family attractive for a variety of applications that require a good balance between cost and performance. The low input bias current supports those operational amplifiers to be used in applications with MΩ source impedances.

The robust design of the OPAx316 provide ease-of-use to the circuit designer–a unity-gain stable, integrated RFI-EMI rejection filter, no phase reversal in overdrive condition, and high electrostatic discharge (ESD) protection (4-kV HBM).

These devices are optimized for low-voltage operation as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V). This latest addition of low-voltage CMOS operational amplifiers, in conjunction with the OPAx313 and OPAx314 provide a family of bandwidth, noise, and power options to meet the needs of a wide variety of applications.

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。
設計工具

CIRCUIT060015 — 可調式參考電壓電路

此電路結合反相及非反相放大器,讓參考電壓可從負輸入電壓向上調整至輸入電壓。可加入增益以提高最大負參考位準。
設計工具

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。
