(1)
All items are SMD except terminal posts. All components are Pb free.
(2)
Due to the very small size of the NanoFree™ WCSP IC package, the standard part number TPA2031D1 is replaced with the code AKO
(Pb-free version).
(3)
Call Digi-Key for Pb-free information.
(4)
Values shown are for EVM revision A only. For non-rev A EVMs, R1 = R2 = 60.4 k Ω , AV = 5 V/V.
The is TPA2031D1 EVM is completely Pb-free. The device, all the components, and the printed-circuit
board are all Pb-free. In addition, no lead is used in the manufacture or assembly of the module.
