SA58637
2 × 2.2 W BTL audio amplifier
Rev. 01 — 25 February 2008
Product data sheet
1. General description
The SA58637 is a two-channel audio amplifier in an HVQFN20 package. It provides
power output of 2.2 W per channel with an 8 Ω load at 9 V supply. The internal circuit is
comprised of two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN
output stage and standby/mute logic. The SA58637 is housed in a 20-pin HVQFN
package, which has an exposed die attach paddle enabling reduced thermal resistance
and increased power dissipation.
2. Features
I Low junction-to-ambient thermal resistance using exposed die attach paddle
I Gain can be fixed with external resistors from 6 dB to 30 dB
I Standby mode controlled by CMOS-compatible levels
I Low standby current < 10 µA
I No switch-on/switch-off plops
I High power supply ripple rejection: 50 dB minimum
I ElectroStatic Discharge (ESD) protection
I Output short circuit to ground protection
I Thermal shutdown protection
3. Applications
I Professional and amateur mobile radio
I Portable consumer products: toys and games
I Personal computer remote speakers
