The TLVx333 series of CMOS operational amplifiers offer precision performance at a very competitive price. These devices are members of the zero-drift family of amplifiers that uses a proprietary auto-calibration technique to simultaneously provide low offset voltage (15 µV, max) and near-zero drift over time and temperature at only 28 µA (max) of quiescent current. The TLVx333 family features rail-to-rail input and output in addition to near-flat 1/f noise, making this amplifier ideal for many applications and much easier to design into a system. These devices are optimized for low-voltage operation as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V).

The TLV333 (single version) is available in the SC70-5, SOT23-5, and SOIC-8 packages. The TLV2333 (dual version) is offered in VSSOP-8 and SOIC-8 packages. The TLV4333 is offered in the standard SOIC-14 and TSSOP-14 packages. All versions are specified for operation from –40°C to +125°C.

CIRCUIT060077 — 低功耗、雙向電流感測電路

這套低功耗、低壓側、雙向電流感測解決方案採用兩個極低功率、零漂移放大器 (LPV821) 和一個含整合式精密參考 (TLV3012) 的微電源比較器。此電路非常適合需要準確監控充電電流和系統電流的電池供電裝置。U1 和 U2 的增益則會獨立設定。如應用電路所示，LPV821 放大器透過 RSENSE 以失相方式連接，以放大反極性的電流。放大器 U2 線性放大充電 (正) 電流，而放大器 U1 線性放大系統 (負) 電流。當 U2 監控正電流時，U1 會將輸出驅動至接地。同樣地，U2 在 U1 監控負電流時，也會將輸出驅動至接地。放大器輸出與電阻器 R7 和 R8 一起進行 OR 運算，而 (...)
