Function
Description
1, 13
VBOOT2, VBOOT1
Bootstrap voltages for gate drive of high side MOSFET s
2
VN10
Floating supply input. Normally connected to the output of onboard VN10 buck
converter. This voltage must be stable and referenced to VNN.
3
VN10GND
Power ground for onboard VN10 generator. Electrically tied to the TA2022 case.
4, 12
VPP2, VPP1
Positive power supply input pins.
5
VN10SW
Switching output voltage for onboard VN10 generator (buck converter).
6
NC
Not connected internally. May be connected to pin 7 without any loss of
functionality or performance.
7,10
OUT2, OUT1
Power amplifier outputs.
8, 9
VNN2, VNN1
Negative power supply inputs.
11
NC
Not connected internally. May be connected to pin 10 without any loss of
functionality or performance.
14
VN10FDBK
Feedback for onboard VN10 generator (nominally 11V above VNN)
15, 20
AGND
Analog Ground.
16, 21
V5
5V power supply input.
17
REF
Used to set internal bias currents. The pin voltage is typically 1.1V.
18
VNNSENSE
Negative supply voltage sense input. This pin is used for both over and under
voltage sensing for the VNN supply.
19
VPPSENSE
Positive supply voltage sense input. This pin is used for both over and under
voltage sensing for the VPP supply.
22, 25
OAOUT1, OAOUT2
Outputs of Input Stage op amps.
23, 26
INV1, INV2
Inverting inputs of Input Stage op amps.
24
MUTE
Logic input. A logic high puts the amplifier in mute mode. Ground pin if not used.
Please refer to the section, Mute Control, in the Application Information.
27
BIASCAP
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.
28, 29
FBKGND2, FBKOUT2
Output voltage differential feedback for channel 2.
30,31
FBKGND1, FBKOUT1
Output voltage differential feedback for channel 1.
32
HMUTE
Logic Output. A logic high indicates both amplifiers are muted, due to the mute
pin state, or a fault such as an overcurrent, undervoltage, or overvoltage
condition.
