The TLV244x and TLV244xA are low-voltage operational amplifiers from Texas Instruments. The common-mode input voltage range of these devices has been extended over typical standard CMOS amplifiers, making them suitable for a wide range of applications. In addition, these devices do not phase invert when the common-mode input is driven to the supply rails. This satisfies most design requirements without paying a premium for rail-to-rail input performance. They also exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. This family is fully characterized at 3-V and 5-V supplies and is optimized for low-voltage operation. Both devices offer comparable ac performance while having lower noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLV244x has increased output drive over previous rail-to-rail operational amplifiers and can drive 600- loads for telecommunications applications.

The other members in the TLV244x family are the low-power, TLV243x, and micro-power, TLV2422, versions.

The TLV244x, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels and low-voltage operation, these devices work well in hand-held monitoring and remote-sensing applications. In addition, the rail-to-rail output feature with single- or split-supplies makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For precision applications, the TLV244xA is available with a maximum input offset voltage of 950 µV.

If the design requires single operational amplifiers, see the TI TLV2211/21/31. This is a family of rail-to-rail output operational amplifiers in the SOT-23 package. Their small size and low power consumption make them ideal for high-density battery-powered equipment.

CIRCUIT060074 — 采用比较器的高侧电流检测电路

该高侧电流检测解决方案使用一个具有轨到轨输入共模范围的比较器，如果负载电流上升至超过 1A，则在比较器输出端 (COMP OUT) 产生过流警报 (OC-Alert) 信号。该实现中的 OC-Alert 信号低电平有效。因此，当超过 1A 阈值后，比较器输出变为低电平。实施磁滞以确保在负载电流减小至 0.5A（减少 50%）时，OC-Alert 返回到逻辑高电平状态。该电路使用漏极开路输出比较器，从而对输出高逻辑电平进行电平转换，以控制数字逻辑输入引脚。对于需要驱动 MOSFET 开关栅极的应用，最好使用具有推挽输出的比较器。
