About This Manual
This user’s guide describes the characteristics, operation, and the use of the
APA100 reference design board. It covers all pertinent areas involved to
properly use this reference design board along with the devices that it
supports. The physical PCB layout, schematic diagram, and circuit
descriptions are included.
This reference design demonstrates how to make the TPA2001D1 and
TAS5111 into a 100-W class-D amplifier. The user’s guide discusses how the
TPA2001D1 is used as an analog input class-D modulator. The analog
modulator is input to the TAS5111, which is an H−bridge that effectively
extends the supply range from the TPA2001D1’s 3-V rails to 29.5 V with the
TAS5111. The user’s guide also goes into detail on the external feedback using
the TLV2464A quad operational amplifier to add power supply rejection. The
user’s guide shows the measured audio results including: total harmonic
distortion plus noise (THD+N) versus frequency, THD+N versus output power,
signal-to-noise ratio (SNR), output power versus supply voltage, output power
versus load, and supply rejection ratio versus frequency.
