Philips Semiconductors Product speciÞcation
Multiple voltage regulator with switch and
ignition bufferTDA3681
FEATURES
General
·
Extremely low noise behaviour and good stability with
very small output capacitors
· Second supply pin for regulators 3 and 4 to reduce
power dissipation (e.g. via a DC-to-DC converter)
· Three V
P-state controlled regulators (regulators 1, 3
and 4) and a power switch
· Regulator 2, reset and ignition buffer operational during
load dump and thermal shutdown
· Combined control...

 GENERAL DESCRIPTION 
The AK5358A is a stereo A/D Conv er ter  w ith w ide sam pling rate of 8kHz  96kHz and is suitable for 
consumer to professional audio system. The AK5358A achieves high accura cy and low cost by using 
Enhanced dual bit 

  techniques. The AK5358A requires no external components because the analog  
inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to 
various systems like DTV, DVR and AV Receiver.
