Part Number:TPA2005D1-Q1
Hello,
my customer wants to use TPA2005D1-Q1 with the single-ended input configuration in order to replace a discrete H-Bridge stage.
The input signal is a PWM (88 KHz) from µC output. Is the IC expected to work with this kind of input signal, or should this IC be just used with a signal generator (sine wave)?
R = 150k and C= 53nF as filter on pin 3 and pin 4 is connected to ground. But the signal is attenuated at the input pin.
Connecting pin 4 with C = 53nF and R = 150k to GND instead of connecting it there directly was done initially and there was just noise on the output.
Are the capacitor values wrong? In the EVM documentation it is in the range of µFs.
SHUTDOWN pin is connected to pin 6 i.e VDD i.e the IC is always enabled.
Is the frequency out of range for this IC?
What is the maximum frequency that it can generate on it’s outputs?
Thanks for your advice!
Martin
