TI’s LMV65x devices are high-performance, low-power operational amplifier ICs implemented with TI’s advanced VIP50 process. This family of parts features 12 MHz of bandwidth while consuming only 116 µA of current, which is an exceptional bandwidth to power ratio in this operational amplifier class. The LMV65x devices are unity-gain stable and provide an excellent solution for general-purpose amplification in low-voltage, low-power applications.

This family of low-voltage, low-power amplifiers provides superior performance and economy in terms of power and space usage. These operational amplifiers have a maximum input offset voltage of 1.5 mV, a rail-to-rail output stage, and an input common-mode voltage range that includes ground. The LMV65x provide a PSRR of 95 dB, a CMRR of 100 dB, and a total harmonic distortion (THD) of 0.003% at 1-kHz frequency and 2-kΩ load.

The operating supply voltage range for this family of parts is from 2.7 V and 5.5 V. These operational amplifiers can operate over a wide temperature range (–40°C to 125°C), making them ideal for automotive applications, sensor applications, and portable equipment applications. The LMV651 is offered in the ultra-tiny 5-pin SC70 and 5-pin SOT-23 package. The LMV652 is offered in an 8-pin VSSOP package. The LMV654 is offered in a 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。
