The low-power TLV904x family includes single (TLV9041), dual (TLV9042), and quad-channel (TLV9044) ultra-low-voltage (1.2 V to 5.5 V) operational amplifiers (op-amps) with rail-to-rail input and output swing capabilities. The TLV904x enables power savings both with its low quiescent current (10 µA, typ.) and the ability to operate at supply voltages as low as 1.2 V, making it one of the few amplifiers in the industry capable of 1.5-V coin cell applications. Further power savings can be achieved using the shutdown mode (TLV9041S, TLV9042S, and TLV9044S) that allows the amplifiers to be switched off and enter into a standby mode with typical current consumption of less than 150 nA. These devices offer a cost-effective amplifier solution for power and space-constrained applications such as battery-powered IoT devices, wearable electronics, and personal electronics where low-voltage operation is crucial.

The robust design of the TLV904x family simplifies circuit design. These op-amps feature an integrated RFI and EMI rejection filter, unity-gain stability, and no-phase reversal in input overdrive conditions. The device also delivers excellent AC performance with a gain bandwidth of 350 kHz and a high cap load drive of 100 pF, enabling designers to achieve both improved performance and lower power consumption.

Space-saving micro-size packages, such as X2QFN and WSON, are offered for all channel variants (single, dual, and quad), along with industry-standard packages such as SOIC, VSSOP, TSSOP, and SOT-23 packages.

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。
