Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the operating range of 2.7V to 5.5V.

2. Input Signals:

   • Keep input signals within the common-mode voltage range to avoid distortion and ensure accurate amplification.
   • Be mindful of the input bias current; use high-impedance sources or buffer stages if necessary.

3. Noise Considerations:

   • For low-noise applications, consider the input voltage noise density at 1 kHz (10 nV/√Hz).

4. Slew Rate:

   • The slew rate of 1.8 V/μs limits the maximum rate of change of the output voltage. Design circuits considering this limitation to prevent signal distortion.

5. Bandwidth:

   • The small-signal bandwidth is 1.6 MHz. Adjust gain settings and feedback networks to stay within this limit for optimal performance.

6. Output Drive Capability:

   • The amplifier can source up to 25 mA in short-circuit conditions. Protect against excessive loading that could exceed this limit.

7. Quiescent Current:

   • Each amplifier consumes 170 μA quiescent current. Factor this into power budget considerations.

8. Common-Mode Rejection Ratio (CMRR) and Power Supply Rejection Ratio (PSRR):

   • Both are specified at 120 dB at 1 kHz. These parameters indicate the amplifier's ability to reject unwanted common-mode and power supply variations, ensuring cleaner output signals.

9. Package Handling:

   • Handle the AD8615AUJZ with care to avoid damage to pins and ensure proper insertion into sockets or PCBs.

10. Thermal Management:

    • Ensure adequate heat dissipation if operating near the upper supply voltage limit or under heavy load conditions.
