Operating from 2.7 V to 16 V over the extended industrial temperature range from –40°C to +125°C, the TLV27x is a low power, wide bandwidth operational amplifier (opamp) with rail to rail output. This makes it an ideal alternative to the TLC27x family for applications where rail-to-rail output swings are essential. The TLV27x provides 3-MHz bandwidth from only 550 µA.

Like the TLC27x, the TLV27x is fully specified for 5-V and ±5-V supplies. The maximum recommended supply voltage is 16 V, which allows the devices to be operated from a variety of rechargeable cells (±8 V supplies down to ±1.35 V).

The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation making an attractive alternative for the TLC27x in battery-powered applications.

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

The 2.7-V operation makes it compatible with Li-Ion powered systems and the operating supply voltage range of many micropower microcontrollers available today including TI’s MSP430.

CIRCUIT060013 — 具有 T 網路回饋電路的反相放大器

此設計可反轉輸入訊號 VIN,並使用 1000 V/V 或 60 dB 訊號增益。具有 T 回饋網路的反相放大器可在沒有較小 R4 值或超大回饋電阻器值的情況下獲得高增益。

設計工具

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。
