1-1 EVM Overview
EVM Overview
This reference design demonstrates how to make the TPA2001D1 and the
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 18-V to 29.5-V power supply is applied across the power supply banana
plugs J3 and J4. Apply 18 V to 29.5 V to J3 and 0 V (ground) to J4. A simple
zener diode and NPN transistor circuit is used to create the 3-V supply for the
TPA2001D1 and TLV2464A; therefore, the user only needs to apply the
single-supply voltage.
The analog single-ended input is received through the phono jack, J5. The
user should connect the load across the differential output banana jacks, J1
and J2.
