1. Supply voltage ratings shown are with oscillator running and all functions operating normally.

2. Clock frequency and duty cycle are ratings for the clock input on pin XT.

3. Output current when 20 kΩ volume control resistor is connected to VOL, and all D/A converter bits ON, measured using the following circuit.
