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.
