The Austrian microelectronics puts out 8 highly most linear passways 8 DAC AS1504s
The Austrian microelectronics is announced, introduce and have shutting off and middle graduation to reset 8 digital-analogue converters (DAC) of 8 passways of low power consumption of the function Series AS1504/05. It is non-linear (INL) that AS1504/05 device can offer the remarkable total mark And the overhanging digit is non-linear (DNL) Ability. The non-linear representative value of its integer is ± 0.15LSB, maximum value is ± 0.75LSB; The digital non-linear representative value is ± 0.1LSB, maximum value is ± 0.5LSB.
Utilize middle graduation to reset, AS1504 becomes the ideal substituting solution of the potentiometer, the all right nominal value of use carries on electron regulation. AS1504 DAC of low power consumption is very suitable for applied bandwidth and alter-cycle control such as the audio frequency or video too, and the gain control of audio frequency or video amplifier. AS1504 is still suitable for other various such as automatic regulation and geometric correction of the CRT display device to need low power consumption and application of high-accuracy DAC.
AS1505 can offer independent control for outputting inner maximum and minimum value of voltage range, in order to set up the voltage of zero graduation separately. So device this make the intersection of voltage and the intersection of control limit and application restrained for those from to receive bring good news because of requiring highest redolution.
AS1504 and AS1505 more than to imitate potentiometers advantages, include offering more high definition, because AS1504/05 DAC has 256 programmable step number and very small volume. This series of products adopt 9.9* 6mm SOIC to capsulate, can substitute 8 simulation potentiometers. In addition, the functions of these devices will not be influenced by mechanical jamming of shaking, assaulting etc.; Will not be influenced by mechanical wear either too, and have low-noise, low temperature drift and high-speed characteristic regulated, contribute to realizing and adjusting fast.
AS1504 and AS1505 can work when supply power in the voltage range in +2.7 to 5.5V. This series of products adopt 16 to guide the foot SOIC-150 to capsulate, has already supplied now.
