双路低电压 LinCMOSTM 差动比较器
The 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.
