Frequently Asked Questions
What must I do if I might exceed the absolute maximum ratings?
Use a physical safety device, such as a fuse, and ensure that no conditions exceeding these maximum ratings will be applied to the LSI IC.
What is the typical recommended supply voltage range (VCC) for operation?
The nominal operating supply voltage range is 4.5 V to 5.5 V, with a typical value of 5.0 V.
How should I ensure proper grounding and stability when installing the device?
You must check whether or not the voltage at each pin, including transient phenomena, remains less than the GND pin voltage at all times.
What is the specified common mode rejection ratio (CMRR)?
The Common Mode Rejection Ratio ranges from -60 to -40 dB when tested with V_in=1.0Vpp and f=20kHz.
