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
APPLICATIONS
D Designed for Wireless or Cellular Handsets
and PDAs
DESCRIPTION
T
he TPA6203A1 is a 1.25-W mono fully differential
amplifier designed to drive a speaker with at least 8-
impedance while consuming less than 37 mm2 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 TPA6203A1 is
available in the space-saving 2 mm x 2 mm MicroStar
Junior
BGA package.
F
eatures like 85-dB PSRR from 90 Hz to 5 kHz,
improved RF-rectification immunity, and small PCB
area makes the TPA6203A1 ideal for wireless
handsets. A fast start-up time of 4
s with minimal pop
makes the TPA6203A1 ideal for PDA applications.
