Pin Description
Pin
2, 3
Function
DCAP2, DCAP1
Description
Charge pump switching pins. DCAP1 (pin 3) is a free running 300kHz square
wave between VDDA and DGND (12Vpp nominal). DCAP2 (pin 2) is level shifted
10 volts above DCAP1 (pin 3) with the same amplitude (12Vpp nominal),
frequency, and phase as DCAP1.

Internal reference voltage; approximately 1.0 VDC.
A logic low output indicates the input signal has overloaded the amplifier.
Input stage output pins.
Single-ended inputs. Inputs are a “virtual” ground of an inverting op-amp 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. This pin should be tied to GND if not used.
Input stage bias voltage (approximately 2.4VDC).
When set to logic high, device goes into low power mode. If not used, this pin
should be grounded
A logic high output indicates thermal overload, or an output is shorted to ground,
or another output.
