TPA6205A1 具有 1.8V 兼容关断电压的 1.25W 单声道全差动 AB 类音频放大器 (TPA6205)

The TPA6205A1 is a 1.25-W mono fully differential amplifierdesigned 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 x 2 mm MicroStar Junior™ BGA package, and the space saving 3 mm x 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 4 µs with minimal pop makes the TPA6205A1 ideal for PDA applications
