Input stage bias voltage (approximately 2.4VDC).
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.
Digital 5VDC, Analog 5VDC
Analog Ground
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 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. This pin should be tied to GND if not used. Unlike previous
Tripath devices, the input bias is still active, even if the MUTE pin is tied to a logic
high.
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.
Power Grounds (high current)
Digital Ground. Connect to AGND locally (near the TA2024C).
Bridged output pairs
Supply pins for high current H-bridges, nominally 12VDC.
Not connected. Not bonded internally.
Analog 12VDC
Charge pump output (nominally 10V above VDDA)
Regulated 5VDC source used to supply power to the input section (pins 4 and 9).
