The TLV238x single supply operational amplifiers provide rail-to-rail input and output capability. The TLV238x takes the minimum operating supply voltage down to 2.7 V over the extended industrial temperature range, while adding the rail-to-rail output swing feature. The TLV238x also provides 160-kHz bandwidth from only 7 µA. The maximum recommended supply voltage is 16 V, which allows the devices to be operated from (±8 V supplies down to ±1.35 V) two rechargeable cells.

The combination of rail-to-rail inputs and outputs make them good upgrades for the TLC27Lx family—offering more bandwidth at a lower quiescent current. The offset voltage is lower than the TLC27LxA variant.

To maintain cost effectiveness the TLV2381/2 are only available in the extended industrial temperature range. This means that one device can be used in a wide range of applications that include PDAs as well as automotive sensor interface.

All members are available in SOIC, with the singles in the small SOT-23 package, duals in the MSOP.

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。
