TI TPA6205A1DGNR

The TPA6205A1 device is a 1.25- W mono fully differential amplifier designed to drive a speaker with at least 8- Q 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 TPA6205A1 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. Features like 85- dB PSRR from 90 Hz to 5 kHz, improved RF- rectification immunity, and small PCB area makes the TPA6205A1 ideal for wireless handsets. A fast start- up time of 4s with minimal pop makes the TPA6205A1 ideal for PDA applications.
