TLV2352ID
TLV 系列低电压比较器### 比较器,Texas InstrumentsTexas Instruments 系列电压比较器不仅包括传统单、双和四路比较器封装,还包括窗口比较器及过压和欠压监控器。 尽管比较器和运算放大器表面上是相似的设备,但它们在实用应用中的操作大大不同。 运算放大器适用于线性操作,附带适当反馈,而比较器定制用于快速切换且通常在开路模式中操作。 专用电压比较器具有明显较短的传播延迟,且可在饱和条件下具有更快的响应时间。 大多数比较器还更耐受高差分输入电压,且很多比较器具有开路集电极输出,从而可与其他设备并联操作。
The TLV2352 consists of two independent, low-power comparators specifically designed for single power-supply applications and operates with power-supply rails as low as 2 V. When powered from a 3-V supply, the typical supply current is only 120 uA.
The TLV2352 is designed using the Texas Instruments LinCMOSTM technology and therefore features an extremely high input impedance typically greater than 1012 , which allows direct interfacing with high-impedance sources. The outputs are N-channel open-drain configurations that require an external pullup resistor to provide a positive output voltage swing, and they can be connected to achieve positive-logic wired-AND relationships. The TLV2352I is fully characterized at 3 V and 5 V for operation from -40°C to 85°C. The TLV2352M is fully characterized at 3 V and 5 V for operation from -55°C to 125°C.
The TLV2352 has internal electrostatic-discharge ESD-protection circuits and has been classified with a 1000-V ESD rating using Human Body Model testing. However, care should be exercised in handling this device as exposure to ESD may result in degradation of the device parametric performance.
