DAC settles quickly for high linearity
The DAC8881 is an attractive option for industrial process control, automatic test equipment, data acquisition systems and communications applications.
Texas Instruments has introduced a 16bit single-channel buffered voltage-output digital-to-analogue convertor (DAC) with excellent linearity (1LSB maximum INL), low noise (24 nV/(rt)Hz) and fast settling time (5.0us) Combined with low power consumption (5mW), the DAC8881 is an attractive option for industrial process control, automatic test equipment, data acquisition systems and communications applications

Power chip makes the most of a single cell
A buck-boost power management IC helps extend battery life in smart phones, digital still cameras and other single-cell lithium-ion powered multimedia devices.
The DAC8881 operates from a single +2.7 to +5.5V power supply and provides a unipolar output.
The output voltage is based on the reference voltage selected and ranges from 1.25 to 5.5V thereby allowing for use in many different applications.
By using an external operational amplifier for offset, the device can also provide a bipolar output with two's complement coding.
The DAC8881 supports a flexible SPI serial interface capable of input data clock frequencies up to 50MHz with 1.8V/3V/5V compatible logic which enables communications with a wide range of DSPs, FPGAs and microprocessors.
The device operates over an extended temperature range of -40 to +105C.
The DAC8881 is available now in a very small QFN-24 (4 x 4mm) package and is priced at US $10.00 each in 100-piece quantities (suggested resale pricing).
Evaluation modules (EVMs) will be available in Q1 2008.
