Press Release Summary:
Operating from 2.7-5.5 V supply, 8-channel AS1504/05 digital-to-analog converters deliver integral nonlinearity of ±0.15 LSB typ, ±0.75 LSB max, and differential nonlinearity of ±0.1 LSB typ, ±0.5 LSB max. Suited for bandwidth and frequency control, AS1504 features mid-scale reset, while AS1505 provides independent control of maximum and minimum values of output voltage range. Both models are available in 16-pin SOIC-150 packaging.

austriamicrosystems Unveils 8-channel 8-Bit DACs with Highest Linearity
Optimized for applications with the need for 8-bit resolution, AS1504/05 digital-to-analog converters deliver highest linearity for 8 analog output channels
Unterpremstaetten, Austria (25 August 2006) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog integrated circuits (ICs) for communication, industrial, medical and automotive applications, today announced its AS1504/05 family of low-power, 8-channel 8-bit DACs with shutdown and midscale reset. The AS1504/05 devices deliver outstanding integral nonlinearity (INL) - of typically ±0.15LSB and a maximum of ±0.75LSB - as well as outstanding differential nonlinearity (DNL) - of typically ±0.1LSB and a maximum of ±0.5LSB.
With a mid-scale reset, austriamicrosystems' AS1504 is ideal for potentiometer replacements where electronic adjustments start at a nominal value. The low-power AS1504 DAC is also ideally suited for bandwidth and frequency control like in audio or video applications and for gain adjustments like in audio or video amplifiers. The AS1504 is also well suited for automatic adjustments and geometric correction in CRT displays and for many other applications where low power and highly accurate DACs are needed.
The AS1505 provides independent control of the maximum and the minimum values of the output voltage range and allows separate zero-scale voltage settings. The device can thus bring significant benefits to applications that have a limited voltage control range since the resolution is maximized.
"The AS1504 and AS1505 offer several advantages over analog potentiometers," said Walter Moshammer, standard linear marketing director at austriamicrosystems. "The advantages include better resolution, since the AS1504/05 DACs have 256 programmable steps and a small form factor. The devices are available in a 9.9x6mm SOIC package which replaces eight analog potentiometers. In addition the functions of the devices are not affected by mechanical disturbances such as vibration or shock. They are also immune to mechanical abrasion, while offering low noise, low temperature drift and high-speed adjustment, which means that fast trimming is possible."
Both the AS1504 and AS1505 operate from a +2.7 to 5.5V supply, and are available in 16-pin SOIC-150 packaging. For product specific information, to download data sheets or to request free samples from austriamicrosystems' online shop ICdirect, please visit
