Instructions for Use:

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 4.5V to 16V.
   • The typical operating voltage is 5V.

2. Supply Current (Icc):

   • The device typically consumes around 2.8mA with no load at 0 Hz frequency.

3. Input Configuration:

   • The input voltage should not exceed Vcc - 1.5V and should be above 0V.
   • The input bias current can range from 20nA to 80nA.

4. Output Configuration:

   • The output voltage swing should be considered when designing circuits, ensuring it stays between 0.5V and Vcc - 1.5V for optimal performance.

5. Performance Parameters:

   • For applications requiring high bandwidth, note that the operational amplifier has a typical bandwidth of 1.2MHz at a gain of +1.
   • The large signal voltage gain is typically 100dB under specified conditions.
   • Pay attention to the slew rate, which is typically 0.3V/渭s, affecting the performance in fast-switching applications.

6. Noise and Rejection Ratios:

   • The common mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) are critical for maintaining signal integrity; they are typically 90dB and 80dB respectively.

7. Handling and Storage:

   • Store in a dry environment and handle with care to avoid static damage.
