TPA3110D2 audio power amplifier pin function and voltage
TPA3110D2 chip pin parameters:
pin
name
describe
one
标准偏差
Audio amplifier logic input turned off (low = output high resistance, high = enabled). TTL logic level compliant AVCC
two
Open leakage output to display or dc detection of short-circuit fault status. Voltage compatible with AVCC. Short-circuit faults can be set for automatic recovery by connecting the needle to SD faults. Otherwise, both short-circuit faults are detected and the fault must be dc reset via cyclic PVCC
three
LINP
This is the left channel audio input. Offset by 3V
four
林
Negative left channel audio input. Offset by 3V
five
GAIN0
Gain selects the least significant bit. Compliant TTL logic level AVCC
six
GAIN1
Gain select the most important point. Compliant TTL logic level AVCC
seven
AVCC
Analog power supply
8
AGND
Analog signal ground. Connect to hot pad
nine
GVDDP
High side grid drive power supply FET. rated voltage is 7V. should also be supplied as PLIMIT function
啡罗啉
限制
Power limit level adjustment. Connect a resistor divider from GVDD GND to set power limits and connect directly to GVDD with no power limits
eleven
RINN
Negative right channel audio input, offset 3V
twelve
RINP
This is the right channel audio input. Offset by 3V
thirteen
