TDA8559T Low voltage stereo headphone amplifier
General description for TDA8559T:
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.
Features for TDA8559T:
- Operating voltage from 1.9 V to 30 V
- Very low quiescent current
- Low distortion
- Few external components
- Differential inputs
- Usable as a mono amplifier in Bridge-Tied Load (BTL) or stereo Single-Ended (SE)
- Single-ended mode without loudspeaker capacitor
- Mute and Standby mode
- Short-circuit proof to ground, to supply voltage (< 10 V) and across load
- No switch on or switch off clicks
- SD protected on all pins
Applications for TDA8559T:
- Portable telephones
- MP3 players
- Portable audio
- Mains fed equipment

TDA1010A 2 x 6W audio power amplifier
Description:
The TDA1010A is a monolithic integrated class-B audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is primarily developed as a 6 W car radio amplifier for use with 4Ωand 2Ωload impedances. The wide supply voltage range and the flexibility of the IC make it an attractive proposition for record players and tape recorders with output powers up to 10 W.
Special features:
