SLOS490TPA6205A1
SLOS490C – JULY 2006 – REVISED NOVEMBER 2015
TPA6205A1 1.25-W Mono Fully Differential Audio Power Amplifier
With 1.8-V Input logic Thresholds
1 Features
3 Description
The TPA6205A1 device is a 1.25-W mono fully
1
1.25 W Into 8-
Ω From a 5-V Supply at THD = 1%
differential amplifier designed to drive a speaker with
(Typical)
at least 8-
Ω impedance while consuming less than 37
Shutdown Pin has 1.8-V Compatible Thresholds
mm2 (ZQV package option) total printed-circuit-board
Low Supply Current: 1.7 mA Typical
(PCB) area in most applications. This device operates
from 2.5 V to 5.5 V, drawing only 1.7 mA of quiescent
Shutdown Current < 10 µA
supply current. The TPA6205A1 is available in the
Only Five External Components
space-saving 2-mm × 2-mm MicroStar Junior BGA
Improved PSRR (90 dB) and Wide Supply
package, and the space saving 3-mm × 3-mm QFN
Voltage (2.5 V to 5.5 V) for Direct Battery
(DRB) package.
Operation
Features like 85-dB PSRR from 90 Hz to 5 kHz,
Fully Differential Design Reduces RF
improved RF-rectification immunity, and small PCB
Rectification
area makes the TPA6205A1 ideal for wireless
handsets. A fast start-up time of 4s with minimal pop
Improved CMRR Eliminates Two Input
makes the TPA6205A1 ideal for PDA applications.
Coupling Capacitors
C(BYPASS) Is Optional Due to Fully Differential
