The TLV522 500 nA dual, nanopower op amp offers optimum price performance in TI’s nanopower family of operational amplifiers. The TLV522 provides 8 kHz of gain bandwidth from 500 nA of quiescent current, making it well suited for battery powered applications found in building automation and remote sensing nodes. Its CMOS input stage enables very low IBIAS, reducing errors commonly introduced in Megaohm feedback resistance topologies such as high-impedance photodiode and charge sense applications. Additionally, built-in EMI protection reduces sensitivity to unwanted RF signals from sources like mobile phones, WiFi, radio transmitters and RFID readers.

The TLV522 is offered in the 8-pin VSSOP (MSOP) package, and operates from –40°C to 125°C.

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。
