Bandgap reference times two (typically 2.5VDC). Used to set the common mode voltage
for the input op amps. This pin is not capable of driving external circuitry.
Positive switching feedback.
Internal mode selection. This pin must be grounded for proper device
operation.
Negative switching feedback.
Test pin. Must be left floating.
Logic output. A logic high indicates both amplifiers are muted, due to the mute pin state, or
a “fault”.
Non-inverted switching modulator outputs.
Inverted switching modulator outputs.
No connect
Over Current Detect. Ground if not used.
Internal reference voltage; approximately 1.2 VDC.
Negative power stage over/under supply voltage sense resistor tie point.
A logic low output indicates the input signal has overloaded the amplifier.
Positive power stage over/under supply voltage sense resistor tie point.
Ground
5 Volt power supply input.
Input stage output pins.
Single-ended inputs. Inputs are a “virtual” ground of an inverting opamp with
approximately 2.4VDC bias.
When set to logic high, both amplifiers are muted and in idle mode. When low (grounded),
both amplifiers are fully operational. If left floating, the device stays in the mute mode.
Ground if not used.
Break-before-make timing control.
