Instructions for Using AD202KY

1. Power Supply:

   • Connect the supply voltage (Vcc) between 4.5V and 16V to the Vcc pin.
   • Ensure a stable power supply to avoid noise and instability.

2. Input Signal:

   • Connect the input signal to the IN+ and IN- pins.
   • The input impedance is 10k惟, so ensure the source impedance is compatible to avoid loading issues.

3. Output Signal:

   • The output signal can be taken from the OUT pin.
   • The output impedance is 2k惟, which should be considered when connecting to subsequent stages.

4. Bandwidth and Gain:

   • The device has a bandwidth of 200kHz and a gain of 34dB.
   • For applications requiring different gain or bandwidth, external components may be necessary.

5. Slew Rate:

   • The slew rate is 0.5V/渭s, which limits the maximum rate of change of the output voltage.
   • Ensure the input signal does not exceed this rate to avoid distortion.

6. Common Mode Rejection Ratio (CMRR):

   • The CMRR is 60dB, indicating good rejection of common-mode signals.
   • This helps in reducing noise and interference.

7. Power-Down Mode:

   • To enter power-down mode, set the PD pin to a high state.
   • In this mode, the current consumption drops to 0.1渭A, significantly reducing power usage.

8. Layout Considerations:

   • Use a ground plane to minimize noise and improve stability.
   • Keep signal traces short and direct to reduce parasitic capacitance and inductance.

9. Operating Temperature:

   • The device operates over a temperature range of -40掳C to +85掳C.
   • Ensure the operating environment stays within these limits to maintain performance.

10. Storage and Handling:

    • Store the device in a dry, static-free environment.
    • Handle with care to avoid damage to the pins and internal components.
