Product Summary

The TPA6205A1DGNR is a 1.25-W mono fully differential amplifier designed to drive a speaker with at least 8-Ω impedance while consuming less than 37 mm 2 (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 TPA6203A1 is available in the space-saving 2 mm × 2 mm MicroStar Junior BGA package, and the space saving 3 mm × 3 mm QFN (DRB) package. The applications of the device include designed for Wireless Handsets, PDAs, and other mobile devices and Compatible with Low Power (1.8V Logic) I/O Threshold control signals.
