SA58631 3 W BTL audio amplier Rev. 02 12 October 2007 Product data sheet 1. General description The SA58631 is a one channel audio amplier in an HVSON8 package. It provides power output of 3 W with an 8 load at 9 V supply. The internal circuit is comprised of a BTL (Bridge Tied Load) amplier with a complementary PNP-NPN output stage and standby/mute logic. The SA58631 is housed in an 8-pin HVSON package which has an exposed die attach paddle enabling reduced thermal resistance and increased power dissipation. 2. Features n Low junction-to-ambient thermal resistance using exposed die attach paddle n Gain can be xed with external resistors from 6 dB to 30 dB n Standby mode controlled by CMOS-compatible levels n Low standby current < 10 A n No switch-on/switch-off plops n High power supply ripple rejection: 50 dB minimum n ElectroStatic Discharge (ESD) protection n Output short circuit to ground protection n Thermal shutdown protection 3. Applications n Professional and amateur mobile radio n Portable consumer products: toys and games n Personal computer remote speakersSA58631 NXP Semiconductors 3 W BTL audio amplier 4.

L 2 Supply voltage ripple rejection is measured at the output with a source impedance of R =0 at the input. s The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail. 3 Supply voltage ripple rejection is measured at the output, with a source impedance of R =0 at the input. s The ripple voltage is a sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS), which is applied to the positive supply rail. 5.
