The TLE2021, TLE2022, and TLE2024 (TLE202x) devices are precision, high-speed, low-power operational amplifiers using a new Texas Instruments state-of-the art bipolar process. These devices combine the best features of the OP21, with a highly improved slew rate and unity-gain bandwidth.

The complementary bipolar process uses isolated vertical pnp transistors that yield dramatic improvement in unity-gain bandwidth and slew rate over similar devices.

The addition of a bias circuit in conjunction with this process results in extremely stable parameters with both time and temperature. Therefore, a precision device remains a precision device even with changes in temperature and over years of use.

This combination of excellent dc performance with a common-mode input voltage range that includes the negative rail makes these devices an excellent choice for low-level signal conditioning applications in either single-supply or split-supply configurations. In addition, these devices offer phase-reversal protection circuitry that eliminates an unexpected change in output states when one of the inputs is less than the negative supply rail.

A variety of available options includes small-outline and chip-carrier versions for high-density systems applications.

The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from –40°C to +85°C. The M-suffix devices are characterized for operation over the full military temperature range of –55°C to +125°C.

ANALOG-ENGINEER-CALC — 類比工程師計算機

類比工程師的計算機旨在加速類比電路設計工程師定期使用的許多重複計算。此基於 PC 的工具提供圖形介面，列出各種常見計算，從使用回饋電阻器設定運算放大器增益到選擇適當的電路設計元件以穩定類比數位轉換器 (ADC) 驅動緩衝電路。

除了作為獨立工具使用外，此計算機還與類比工程師口袋參考中描述的概念相得益彰。

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。

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。
