Texas Instrument’s LMV851/LMV852/LMV854 are CMOS input, low power op amp ICs, providing a low input bias current, a wide temperature range of −40°C to +125°C and exceptional performance, making them robust general purpose parts. Additionally, the LMV851/LMV852/LMV854 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV851/LMV852/LMV854 feature 8 MHz of bandwidth while consuming only 0.4 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV851/LMV852/LMV854 provide superior performance and economy in terms of power and space usage. This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating supply range from 2.7V to 5.5V the LMV851/LMV852/LMV854 provide a CMRR of 92 dB, and a PSRR of 93 dB. The LMV851/LMV852/LMV854 are offered in the space saving 5-Pin SC70 package, the 8-Pin VSSOP and the 14-Pin TSSOP package.

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。
