SPEMA2004A
1.7W Mono Fully Differential
Audio Power Amplifier
RoHS Compliant Product
A suffix of “-C” specifies halogen or lead -free
DESCRIPTION
The SPEMA2004A is a 1.7W mono fully differential amplifier designed to drive a speaker with at least 8Ω
impedance while consuming only 20 mm2 total PCB area in most applications. The device operates from 2.5 V to 5.5 V,
drawing only 4mA of quiescent supply current. The SPEMA2004A is available in the space-saving 3 mm x 3 mm FBP
package.
The SPEMA2004A is ideal for PDA/smart phone applications due to features such as -70dB supply voltage
rejection from 20 Hz to 2 kHz, improved RF rectification immunity, small PCB area, and a fast startup with minimal pop.
FEATURES
z Designed for Wireless or Cellular Handsets and PDAs z Improved PSRR (-70 dB) and Wide Supply Voltage (2.5
z 1.7 W Into 8Ω From a 5-V Supply at THD = 10% (Typ) V to 5.5 V) for Direct Battery Operation
z Low Supply Current: 5mA (Typ) at 5 V
z Fully Differential Design Reduces RF Rectification
z Shutdown Current: 0.1 μA (Typ)
z -63 dB CMRR Eliminates Two Input Coupling
z Fast Startup With Minimal Pop
Capacitors
z Only Three External Components
z Pin to Pin Compatible with TPA2005D1 and
TPA6211A1 in FBP Package
z Available in 3 mm X 3 mm TDFN Package
