Austrian microelectronics company (Austriamicrosystems) is rolled out have shut and function of replacement of the scale intermediate (the low power comsumption of Mid-scale Reset) 8 channel converter of 8 digit model (DAC)AS1504 and AD1505, new package has good integral nonlinear (INL) and poor cent are nonlinear (DNL) ability, its integral is nonlinear typical cost is ±0.15LSB, maximum can amount to ±0.75LSB; Poor cent is nonlinear typical cost is ±0.1LSB, maximum is ±0.5LSB.
　　
The ideal that the function of intermediate scale replacement of AS1504 makes its become potentiometer replaces a solution, can use nominal value (Nominal Value) undertakes electronic adjustment. The frequency that the AS1504 DAC of low power comsumption also suits to be used at the application such as frequency or video signal very is wide control with frequency, and the gain of frequency or video signal amplifier adjusts. In addition, what AS1504 still applies to CRT monitor is self-adjusting with geometry corrective, and other all sorts of application that need low power comsumption and high accuracy DAC.

AS1505 is output inside voltage limits the biggest offer independent control with the least value, have set of 0 scale voltage in order to part, suit to need high resolution and make voltage controls limits to accept bounds application. Because AS1504/05 DAC has 256 but the program turns measure, because this can offer higher resolution. It is OK that this series product uses 9.9×6mm SOIC to enclose replace 8 imitate potentiometer. In addition, the function of new package does not suffer shake, the influence of mechanical interference place such as concussion, and won't by mechanical wear.
