TPA6203A1 Datasheet | Texas Instruments

FEATURES - 2 1.25 W Into 8 Ω From a 5-V Supply at THD = 1% (Typical) - Low Supply Current: 1.7 m A Typical - Shutdown Control < 10 µA - Only Five External ponents - Improved PSRR (90 d B) and Wide Supply Voltage (2.5 V to 5.5 V) for Direct Battery Operation - Fully Differential Design Reduces RF Rectification - Improved CMRR Eliminates Two Input Coupling Capacitors - C(BYPASS) Is Optional Due to Fully Differential Design and High PSRR - Avaliable in a 2 mm x 2 mm Micro Star Junior ™ BGA Package (GQV, ZQV) - Available in 3 mm x 3 mm QFN Package (DRB) - Available in an 8-Pin Power PAD™ MSOP (DGN) APPLICATION CIRCUIT APPLICATIONS - Designed for Wireless or Cellular Handsets and PDAs DESCRIPTION The TPA6203A1 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 m A of quiescent supply current. The TPA6203A1 is available in the space-saving 2 mm x 2 mm Micro Star Junior™ BGA package, and the space saving 3 mm x 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 TPA6203A1 ideal for wireless handsets. A fast start-up time of 4 µs with minimal pop makes the TPA6203A1 ideal for PDA applications.
