SA58637

The SA58637 is a two-channel audio amplifier in an HVQFN20 package. It provides power output of 2.2W with an 8 load at 9V supply. The internal ciruit is comprised of two BTL atandby/mute logic. SA58637 is could be used in (1)professional and amateur mobile radio; (2)portable consumer products: toys and  games; (3)personal computer remote speakers.

The features of the SA58637 is (1)low junction-to-ambient thermal resistance using exposed die attach paddle; (2)gain can be fixed with exteral resistors from 6dB to 30dB; (3)Standby mode controlled by CMOS-compatible levels; (4)low standby current<10uA; (5)no switch-on /switch-off plops; (6)high power supply ripple rejection:50dB minimum; (7)electrostatic discharge proction; (8)output short circuit to ground protection; (9)thermal shutdown protection.

The absolute maximum rating system of the SA58637 is as following mentioned:(1)supply voltage: 2.2 to 18V; (2)quiescent current: 15 to 22mA; (3)standby current: 10uA; (4)output power :1.2 to 1.5W; (5)total harmonic distortion-plus-noise:0.15 to 0.3; (6)power supply rejection ratio: 50dB.
