The TPA6202A1 is a 1.25W mono amplifier designed to drive a speaker with at least 8-

Ώ

.

impedance while consuming less than 37 mm2 (ZQV package option) total printed-circuit board
(PCB) area in most applications. This device operates from 2.5V to 5.5V, drawing only 1.7mA of
quiescent supply current.

The TPA6202A1 is available in the space-saving 2 mm x 2 mm MicroStar Junior™ BGA

package.

A fast start-up time of 4ms with minimal pop makes the TPA6202A1 ideal for wireless

handsets.
