Instructions for Use

1. Supply Voltage Setup:

   • Ensure the supply voltage is within the range of 4.5V to 16V.
   • Connect VCC to the power supply and GND to the ground.

2. Input Configuration:

   • The input voltage should not exceed VCC - 2V or go below 0V relative to GND.
   • Connect the input signals accordingly ensuring they stay within the specified limits.

3. Output Configuration:

   • Configure output loads so that the output voltage remains between 0V and VCC - 2V relative to GND.
   • Each channel can source up to 20mA; ensure the load does not exceed this limit.

4. Power Management:

   • For minimal power consumption, utilize the shutdown feature by pulling the SD pin low.
   • In normal operation, the quiescent current is around 35μA.

5. Performance Optimization:

   • To minimize crosstalk between channels, especially at higher frequencies, carefully route the PCB traces.
   • For better PSRR, use a clean power supply and consider adding bypass capacitors close to the device.

6. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C.
   • Be mindful of thermal management if operating near the upper temperature limit.

Note: Always refer to the latest datasheet from the manufacturer for detailed specifications and additional information.
