TDA8586
Philips Semiconductors
Power amplifier with load detection and
auto BTL/SE selection
Preliminary specification
TDA8586
FEATURES
General
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).
GENERAL DESCRIPTION
The IC 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 IC 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).
Protection
Short-circuit proof to ground, positive supply voltage on
all pins and across load
ESD protected on all pins
Thermal protection against temperatures exceeding
150 °C
Load dump protection
Overvoltage protection.
