TDA8586

Features:

` Operating voltage from 8 to 18 V
` Low distortion
` Few external components, fixed gain
` Automatic mode selection (SE or BTL) depending on connected 'rear' loads
` Can be used as a stereo amplifier in Bridge-Tied Load (BTL) or quad Single-Ended (SE) amplifiers
` Single-ended mode without loudspeaker capacitor
` Soft clipping, to guarantee good clip behaviour with inductive loads
` Mute and standby mode with one-pin operation
` Diagnostic information for Dynamic Distortion Detector (DDD), high temperature (140 °C) mode of operation and short-circuit
` No switch-on/off plops when switching between standby and mute and from mute to on
` Load detection on 'rear' channels when switching from standby to mute
` Fast mute on supply voltage drops (low VP mute).

Description

The TDA8586 incorporates the following functions:
1. 4×6 W SE amplifies without SE capacitor, because of the availability of 2 half supply voltage power buffers
2. 2×20 W BTL amplifiers
3. Automatic switching between 2 and 4 speaker operation. The mode of operation is determined during start-up.

This amplifier is protected for all general short-circuit conditions to battery or ground, overvoltage, 45 V load dump and short-circuits on the speaker outputs.

The TDA8586 is contained in a 20-pin power HSOP package, but is also available in a 17-pin SIL power package. When packaged in the 20-pin HSOP package additional functions are available:
1. DDD level selection between 2 and 10%
2. Overrule pin for changing mode of operation (from SE to BTL or from BTL to SE).
