This device operates from 2.5 V to 5.5 V, drawing only 1.7 m A of quiescent supply current. The TPA6205A1 is available in the space-saving 2-mm × 2-mm Micro Star Junior BGA package, and the space saving 3-mm × 3-mm QFN (DRB) package. Features like 85-d B PSRR from 90 Hz to 5 k Hz, 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.
