The TLC27M4 and TLC27M9 quad operational amplifiers combine a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise, and speeds comparable to that of general-purpose bipolar devices.These devices use Texas Instruments silicon-gate LinCMOSTM
LinCMOS is a trademark of Texas Instruments Incorporated. technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes.
The extremely high input impedance, low bias currents, make these cost-effective devices ideal for applications that have previously been reserved for general-purpose bipolar products, but with only a fraction of the power consumption.
Four offset voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC27M4 (10 mV) to the high-precision TLC27M9 (900 uV). These advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available on LinCMOSTM operational amplifiers, without the power penalties of bipolar technology. General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the TLC27M4 and TLC27M9. The devices also exhibit low voltage single-supply operation, and low power consumption, making them ideally suited for remote and inaccessible battery-powered applications. The common-mode input voltage range includes the negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density system applications.
The device inputs and outputs are designed to withstand -100-mA surge currents without sustaining latch-up.
The TLC27M4 and TLC27M9 incorporate internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015; however, care should be exercised in handling these devices, as exposure to ESD may result in the degradation of the device parametric performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from -40°C to 85°C. The M-suffix devices are characterized for operation over the full military temperature range of -55°C to 125°C.

该电路结合了一个反相和同相放大器，可使基准电压在正负输入电压范围内进行调节。可通过增加增益来提高最大负基准电压电平。CIRCUIT060074 — 采用比较器的高侧电流感应电路
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。
