STK403-440

Manufacturer Part Number
STK403-440
Description
6-Channel Class AB Audio Power Amplifier IC
Manufacturer
Sanyo
Datasheet
Ordering number : ENN*7375
Preliminary
Overview
The STK403-400 series products are audio power
amplifier hybrid ICs that consist of optimally-designed
discrete component power amplifier circuits that have
been miniaturized using SANYO’s unique insulated metal
substrate technology (IMST). The adoption of a newly-
developed low thermal resistance substrate allows this
product to integrate six power amplifier channels in a
single compact package. The adoption of a standby circuit
in this device allows it to reduce impulse noise
significantly as compared to earlier Sanyo products, in
particular, the STK402-*00 series products.
Features
• Series of pin compatible power amplifiers ranging from
• Miniature packages
• Output load impedance: R
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby and muting circuits.
30 W/ch to 45 W/ch (10%/1 kHz) devices. The same
printed circuit board can be used depending on the
output power grade.
