Product Summary
The TPA6205A1DRBT is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least 8-W impedance while consuming less than 37 mm2 (ZQV package option) total printed-circuit board (PCB) area in most applications. This device operates from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent supply current. The TPA6205A1DRBT is available in the space-saving 2 mm x 2 mm MicroStar Junior. BGA package, and the space saving 3 mm x 3 mm QFN (DRB) package. The applications of the TPA6205A1DRBT include Designed for Wireless Handsets, PDAs, and other mobile devices, Compatible with Low Power (1.8V Logic) I/O Threshold control signals.
