LMV951
- (Typical 1-V Supply, Unless Otherwise Noted)
- Ensured 1-V, 380-µA Single-Supply Operation
- Shutdown to 50-nA Supply Current
- Wide 2.7-MHz Bandwidth
- Rail-to-Rail Input With Zero Crossover
- No Input IBIAS Current Reversal Over VCM Range
- 1000-pF Output Drive Capability
- High-Output Drive Capability
- Sink Current: 35 mA
- Source Current: 45 mA
- Rail-to-Rail Buffered Output
- At 600-Ω Load, 32 mV from Either Rail
- At 2-kΩ Load, 12 mV from Either Rail
- Temperature Range –40°C to 125°C
The LMV951 amplifier is capable of operating at supply voltages from 0.9 V to 3 V with specified specs at 1-V and 1.8-V single supply.
The input common-mode range extends to both power supply rails without the offset transition zone and input bias current reversal inherent to most rail-to-rail input amplifiers.
Contrary to a conventional rail-to-rail output amplifier, the LMV951 has a buffered
output stage, providing an open-loop gain which is relatively unaffected by resistive output
loading. At 1-V supply voltage, the LMV951 is able to source and sink in excess of
35 mA and offers a gain bandwidth product of 2.7 MHz.
In shutdown mode, the LMV951 consumes less than 50 nA of supply current.

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。
