TDA8559T - Low-voltage stereo headphone amplifier

General Description

The TDA8559T is a stereo amplifier that operates over a wide supply voltage range from 1.9 V to 30 V and consumes a very low quiescent current.

This makes it suitable for battery fed applications (2 × 1.5 V cells).

Key Features

TDA8559T Low-voltage stereo headphone amplifier Rev. 03 — 15 May 2006 Product data sheets 1. General description The TDA8559T is a stereo amplifier that operates over a wide supply voltage range from 1.9 V to 30 V and consumes a very low quiescent current. This makes it suitable for battery fed applications (2 × 1.5 V cells). Because of an internal voltage buffer, this device can be used with or without a capacitor connected in series with the load. It can be applied as a headphone amplifier, but also as a mono amplifier with a small speaker (25 Ω), or as a line driver in mains applications. 2. Features I Operating voltage from 1.
