LAYOUT RECOMMENDATIONS
A proposed layout for the TPA6138A2 can be seen in the TPA6138A2EVM User's Guide, and the Gerber files
can be downloaded from http://www.ti.com. To access this information, open the TPA6138A2 product folder and
look in the Tools and Software folder.
GAIN-SETTING RESISTORS
The gain-setting resistors, RIN and Rfb, must be placed close to pins 13 and 17, respectively, to minimize
capacitive loading on these input pins and to ensure maximum stability of the TPA6138A2. For the
recommended PCB layout, see the TPA6138A2EVM User's Guide.
APPLICATION CIRCUIT
R1 = 15 k
Ω, R2 = 30 kΩ, R3 = 43 kΩ, C1 = 47 pF, C2 = 180 pF
