Instructions for STA460C

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
   • Use a stable power source to avoid fluctuations that could affect performance.

2. Quiescent Current:

   • The quiescent current is typically 1.5mA at 5V supply voltage and room temperature (25掳C).

3. Output Power:

   • The typical continuous output power into an 8惟 load is 2.5W with a total harmonic distortion (THD) of 10%.

4. Efficiency:

   • The efficiency is typically 75% at the maximum output power (2.5W) when Vcc = 5V and the frequency is 1kHz.

5. Total Harmonic Distortion + Noise (THD+N):

   • The THD+N should not exceed 0.1% at 1W output power, 5V supply voltage, and 1kHz frequency.

6. Signal-to-Noise Ratio (SNR):

   • The SNR is typically 95dB, which is A-weighted, ensuring good audio quality.

7. Input Sensitivity:

   • The input sensitivity is between 200mVrms and 400mVrms for 1W output power at 5V supply voltage and 1kHz frequency.

8. Input Impedance:

   • The input impedance is typically 10k惟, which helps in matching with various audio sources.

9. Shutdown Current:

   • When the device is in shutdown mode, the current consumption is typically 1渭A.

10. Operating Temperature:

    • The device can operate within a temperature range of -40掳C to 85掳C.

11. Storage Temperature:

    • The storage temperature range is -65掳C to 150掳C, allowing for safe storage under extreme conditions.

12. Handling:

    • Handle the device with care to avoid static discharge, which can damage the internal components.
    • Follow proper soldering techniques to ensure reliable connections.

13. Mounting:

    • Ensure proper heat dissipation by mounting the device on a heatsink if operating at high power levels or in high ambient temperatures.

14. Testing:

    • Before final assembly, test the device under typical operating conditions to verify performance parameters.
