TC2001 Audio Signal Processor Pin Descriptions
Pin
Function
1
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.
2, 6
FBKGND2,
FBKGND1
3
DCMP
Internal mode selection. This pin must be grounded for proper device
operation.
4, 7
FBKOUT2,
FBKOUT1
5
VPWR
Test pin. Must be left floating.
8
HMUTE
Logic output. A logic high indicates both amplifiers are muted, due to the
mute pin state, or a “fault”.
9, 12
Y1, Y2
Non-inverted switching modulator outputs.
10, 11
Y1B, Y2B
Inverted switching modulator outputs.
13
NC
No connect
14
OCD2
Over Current Detect input.
15
REF
Internal bandgap reference voltage; approximately 1.2 VDC.
16
OCD1
Over Current Detect input.
17
VNNSENSE
Negative supply voltage sense input. This pin is used for both over and
under voltage sensing for the VNN supply.
18
OVRLDB
A logic low output indicates the input signal has overloaded the amplifier.
19
VPPSENSE
Positive supply voltage sense input. This pin is used for both over and
under voltage sensing for the VPP supply.
20
AGND
Ground.
21
V5
5 Volt power supply input.
22, 27
OAOUT1, OAOUT2
Input stage output pins.
23, 28
IN1, IN2
Single-ended inputs. Inputs are a “virtual” ground of an inverting opamp
with approximately 2.4VDC bias.
24
MUTE
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.
25, 26
BBM1, BBM0
Break-before-make timing control to prevent shoot-through in the output
MOSFETs.
