DAC family offers its own upgrade path
Ultra-low-power two- and four-channel digital-analogue convertors offer a choice of 8, 10 and 12bit resolutions.
National Semiconductor has expanded its portfolio of digital-to-analogue convertors (DACs) with the introduction of six new, ultra-low-power, two- and four-channel DACs in 8, 10 and 12bit resolutions The DACs are offered in tiny 3 x 3mm LLP packages as well as MSOPs

National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
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.
Each DAC consumes very little power and has typical settling times of 3 to 6us over a supply range of 2.7 to 5.5V.
For example, the DAC122S085, a 12bit, two-channel DAC, consumes less than 1.5mW (maximum) at 3.6V in normal operation and less than 0.2uW (typically) in power-down mode.
This low power consumption makes these DACs well-suited for portable, battery-powered applications in industrial, medical and consumer markets.
National's DACs and ADCs allow designers to develop a single standard PC board layout that can support multiple devices for seamless upgradeability.
Over the past two years, National has released more than 50 ADCs and DACs.
The new DACs are interchangeable, providing customers with a wide selection of resolution and channel options for a broad range of applications.
The DAC124S085, a 12bit, four-channel DAC, has a typical integral nonlinearity (INL) of less than +/-2.3LSB and a typical differential nonlinearity (DNL) of less than +/-0.15LSB.
Each DAC has a rail-to-rail output swing, uses an external reference and operates over a temperature range of -40 to +105C.
In addition, each DAC can accept input clock rates up to 30MHz over the entire supply range of 2.7 to 5.25V.
Prices start at $1.20 for the DAC082S085 in 1000-unit quantities.
The MSOP products are available now and the DACs in LLP packaging will be released this summer.
