The TLC2272A and TLC2274A are dual and quadruple operational amplifiers from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC227xA family offers 2 MHz of bandwidth and 3 V/µs of slew rate for higher speed applications. These devices offer comparable ac performance while having better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC227xA has a noise voltage of 9 nV/Hz, two times lower than competitive solutions.

The TLC227xA, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micro-power dissipation levels, 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 TLC227xA family has a maximum input offset voltage of 950 µV. This family is fully characterized at 5 V and ±5 V.

The TLC2272/4 also makes great upgrades to the TLC272/4 or TS272/4 in standard designs. They offer increased output dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to be used in a wider range of applications.

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。实现了迟滞，使得当负载电流减小至 0.5 A（减少 50%）时，OC-Alert 将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。
