SPEMA2004A

1.7W Mono Fully Differential

Audio Power Amplifier

Elektronische Bauelemente

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

Designed for Wireless or Cellular Handsets and PDAs

1.7 W Into 8Ω From a 5-V Supply at THD = 10% (Typ)

Low Supply Current: 5mA (Typ) at 5 V

Shutdown Current: 0.1 μA (Typ)

Fast Startup With Minimal Pop

Only Three External Components

Improved PSRR (-70 dB) and Wide Supply Voltage (2.5

V to 5.5 V) for Direct Battery Operation

Fully Differential Design Reduces RF Rectification

-63 dB CMRR Eliminates Two Input Coupling

Capacitors

Pin to Pin Compatible with TPA2005D1 and

TPA6211A1 in FBP Package

Available in 3 mm X 3 mm TDFN Package
