TDA7050T - NXP

TDA7050T Low voltage mono/stereo power amplifier

TDA7050T The TDA7050T is a low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios) in mono (bridge-tied load) or stereo applications. Features • Limited to battery supply application only (typ. 3 and 4 V) • Operates with supply voltage down to 1,6 V • No external components required • Very low quiescent current •.

Features

• Limited to battery supply application only (typ. 3 and 4 V)
• Operates with supply voltage down to 1,6 V
• No external components required
• Very low quiescent current
• Fixed integrated gain of 26 dB, floating differential input
• Flexibility in use − mono BTL as well as stereo
• Small dimension of encapsulation (see package design example). QUICK REFERENCE DATA Supply voltage range Total quiescent current (at VP = 3 V) Bridge tied load application (BTL) Output power at RL = 32 Ω VP = 3 V; dtot = 10% D.C. output offset voltage between the outputs Noise output voltage (r.m.s. value) at f = 1.
