The LPV3xx-N are low power (9-µA per channel at 5 V) versions of the LMV3xx op amps. This is another addition to the LMV family of commodity op amps.

The LPV3xx-N are the most cost effective solutions for the applications where low voltage, low power operation, space saving and low price are needed. The LPV3xx-N have rail-to-rail output swing capability and the input common-mode voltage range includes ground. They all exhibit excellent speed-power ratio, achieving 152 kHz of bandwidth with a supply current of only 9 µA.

The LPV321-N is available in space saving 5-Pin SC70, which is approximately half the size of 5-Pin SOT-23. The small package saves space on PC boards, and enables the design of small portable electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity.

The chips are built with Texas Instruments's advanced submicron silicon-gate BiCMOS process. The LPV3xx-N have bipolar input and output stages for improved noise performance and higher output current drive.

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。
