The TLV313 family of single-, dual-, and quad-channel precision operational amplifiers combine low power consumption with good performance. This makes them suitable for a wide range of applications, such as wearables, utility metering, building automation, currency counters and more. The family features rail-to-rail input and output (RRIO) swings, low quiescent current (65 µA, typical), wide bandwidth (1 MHz) and very low noise (26 nV/√Hz at 1 kHz), making it attractive for a variety of battery-powered applications that require a good balance between cost and performance. Further, low-input-bias current enables these devices to be used in applications with megaohm source impedances.

The robust design of the TLV313 devices provides ease-of-use to the circuit designer: unity-gain stability with capacitive loads of up to 150 pF, integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-kV HBM).

The devices are optimized for operation at voltages as low as +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V), and are specified over the extended temperature range of –40°C to +125°C.

The single-channel TLV313 device is available in both SC70-5 and SOT23-5 packages. The dual-channel TLV2313 device is offered in SOIC-8 and VSSOP-8 packages, and the quad-channel TLV4313 device is offered in a TSSOP-14 package.

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。
