TPA6205A1 的說明
The TPA6205A1 device 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 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.
