7812 datasheet


These voltage regulators are monolithic integrated circuits designed as fixed–voltage regulators for a wide variety of applications including local, on–card regulation. These regulators employ internal current limiting,
thermal shutdown, and safe–area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

R2S15904SP datasheet

Description :

The R2S15904SP is an optimum audio signal processor IC for TV. The IC has a 5ch input selector, surround/pseudo stereo, tone control(2band), output gain control and 2ch master volume. The IC can control all of these functions with I2C bus.


1.  Volume: 0 to –89dB, –∞/ 1dB step. Each channel is independence control.
2.  5 input selector + MUTE
3.  2 Rec output (0/–2dB)
4.  Auto gain control (AGC level 4step)
5.  Tone control Bass: –15dB to +15dB/ 1dB step, Treble: –15dB to +15dB/ 1dB step
6.  Surround <Low/ High>/ Pseudo stereo
7.  Mode selector: Bypass/ Tone / Tone & Pseudo Stereo or Surround
8.  Output gain control: 0dB/ +4.5dB
