BD7836EFV
●Description BD7836EFV is a Class-AB stereo speaker amplifier, developed for note-book PC, desktop PC, portable devices and others. Class-AB amplifier has no EMI noise. Power package HTSSOP-B20 can realize high output power. Low circuit current at active mode reduce consumption of battery. Shutdown current is 0.1µA typically, and pop noise level when shutdown turns on and off is very small. This device is suitable for the application that often changes mode between “shutdown state” and “active state”.
●Features 1) High power 1.9W typ. (VDD=5V, RL=4Ω, THD+N=1%, stereo input) High power 1.2W typ. (VDD=5V, RL=8Ω, THD+N=1%, stereo input) 2) Gain selectable by the external control (6,10,15.6,21.6d B) 3) Pop noise suppression circuitry 4) Shutdown function (also Mute function) [Isd=0.1µA(typ.)] 5) Protection circuitry (Thermal shutdown, Under voltage lockout) 6) Power Package with thermal pad HTSSOP-B20
●Applications Note-book PC, Desktop PC, etc.
●Absolute maximum ratings (Ta=+25℃)

Frequently Asked Questions
What are the typical output power ratings for 4Ω and 8Ω speakers?
With a 5V supply, it delivers 1.9W typical into a 4Ω load and 1.2W typical into an 8Ω load (THD+N=1%).
How do I adjust the amplifier's gain?
You select from four gains (6, 10, 15.6, or 21.6 dB) by setting the Hi/Lo levels on the external GAIN0 and GAIN1 pins.
What is the shutdown current?
The typical shutdown current is only 0.1µA, which is very low for battery-powered applications.
What protection features are included?
The amplifier includes protection circuitry for thermal shutdown and under-voltage lockout.
