National Semiconductor has expanded its data conversion portfolio with the introduction of three pin- and function-compatible 8, 10 and 12bit digital-to-analogue convertors (DACs) These DACs complement National's recently announced family of 36 general-purpose analogue-to-digital convertors (ADCs) and allow National to offer customers an expanded analogue signal-path solution

World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
"National's versatile, pin- and function-compatible DACs enhance our analogue signal-path product offerings and allow us to provide customers with operational amplifiers, ADCs, DACs and interface solutions optimised for analogue signal-path applications", said Uwe Kopp, Product Marketing Manager for National's Data Conversion Division in Europe.
Each of the three DACs provides rail-to-rail output swing and input clock rates of 30MHz on the SPI bus over the entire supply range of 2.7 to 5.25V.
The reference for each is derived from the power supply, resulting in the widest possible dynamic output range.
A power-down feature reduces power consumption to less than 0.2uW, which is especially important for portable, battery-powered applications.
In portable industrial instruments, performance and power are critical issues.
The DAC121S101, for example, can be used to trim offset or gain, or generate high-performance analogue output signals for control or display.
Combined with National's ADCs, amplifiers and other analogue products, customers can build a complete signal-path solution around the microprocessor, field programmable gate array or digital signal processor that meets specific performance and power requirements.
The DACs are designed to optimise performance and minimise power.
For example, the 12bit DAC provides typical performance of +0.25, -0.15LSB (least significant bit) DNL (differential nonlinearity), +/-2.6LSB INL (integral nonlinearity) and power consumption of 0.64mW at 3.6V.
Budgetary 1000-off pricing starts at $1.35 for the DAC121S101.
