Can the LM4651/52 be used with a single supply instead of a dual supply?
Yes. The performance with single supply is the same as with dual supply. The single supply voltage minimum is double the dual supply minimum. The dual supply minimum is +/-11V so the single supply minimum is 22V. A reference voltage of 12V up to ½Vcc must be provided as the GND connections to the LM4651/52 chip set. Vee connections then become 0V (single supply GND) and Vcc connections are the single supply voltage. This voltage reference can be created with a resistor divider, a resistor and a Zener diode or a voltage regulator. Bypass capacitors will need to change connections with capacitors now added on the reference voltage to the single supply GND. The voltage rating of these capacitors will need to be higher than a dual supply configuration.
