The TLV233x operational amplifiers are in a family of devices that has been specifically designed for use in low-voltage single-supply applications. Unlike the TLV2322 which is optimized for ultra-low power, the TLV233x is designed to provide a combination of low power and good ac performance. Each amplifier is fully functional down to a minimum supply voltage of 2 V, is fully characterized, tested, and specified at both 3-V and 5-V power supplies. The common-mode input-voltage range includes the negative rail and extends to within 1 V of the positive rail.

Having a maximum supply current of only 310 uA per amplifier over full temperature range, the TLV233x devices offer a combination of good ac performance and microampere supply currents. From a 3-V power supply, the amplifier's typical slew rate is 0.38 V/us and its bandwidth is 300 kHz.

These amplifiers offer a level of ac performance greater than that of many other devices operating at comparable power levels. The TLV233x operational amplifiers are especially well suited for use in low-current or battery-powered applications.

Low-voltage and low-power operation has been made possible by using the Texas Instruments silicon-gate LinCMOSTM technology. The LinCMOS process also features extremely high input impedance and ultra-low bias currents making these amplifiers ideal for interfacing to high-impedance sources such as sensor circuits or filter applications.

To facilitate the design of small portable equipment, the TLV233x is made available in a wide range of package options, including the small-outline and thin-shrink small-outline package (TSSOP). The TSSOP package has significantly reduced dimensions compared to a standard surface-mount package. Its maximum height of only 1.1 mm makes it particularly attractive when space is critical.

The device inputs and outputs are designed to withstand -100-mA currents without sustaining latch-up. The TLV233x incorporates internal ESD-protection circuits that prevents functional failures at voltages up to 2000 V as tested under MIL-STD 883C, Method 3015.2; however, care should be exercised in handling these devices as exposure to ESD may result in the degradation of the device parametric performance.

CIRCUIT060074 — 采用比較器的高側電流檢測電路

該高側電流檢測解決方案使用一個具有軌到軌輸入共模范圍的比較器，如果負載電流上升至超過 1A，則在比較器輸出端 (COMP OUT) 產生過流警報 (OC-Alert) 信號。該實現中的 OC-Alert 信號低電平有效。因此，當超過 1A 閾值后，比較器輸出變為低電平。實施磁滯以確保在負載電流減小至 0.5A（減少 50%）時，OC-Alert 返回到邏輯高電平狀態。該電路使用漏極開路輸出比較器，從而對輸出高邏輯電平進行電平轉換，以控制數字邏輯輸入引腳。對于需要驅動 MOSFET 開關柵極的應用，最好使用具有推挽輸出的比較器。
