DAC delivers low noise, high accuracy

Dallas, Tex. — Texas Instruments Inc. (TI) has introduced a 16-bit, single-channel, buffered voltage-output digital-to-analog converter (DAC) that features excellent linearity (1 LSB max INL), low noise (24 nV/rtHz) and fast settling time (5.0 us). Combined with low-power consumption of 5 mW, the DAC8881 is suitable for industrial process control, automatic test equipment, data acquisition systems and communications applications.

The DAC8881 operates from a single +2.7-V to +5.5-V power supply and provides a unipolar output. The output voltage is based on the reference voltage selected and ranges from 1.25 V to 5.5 V thereby allowing for use in many different applications, said TI. By using an external operational amplifier for offset, the device can also provide a bipolar output with 2's complement coding.

The DAC8881 supports a SPI serial interface capable of input data clock frequencies up to 50 MHz with 1.8 V/3 V/5 V compatible logic, which enables communications with a wide range of DSPs, FPGAs and microprocessors. The device operates over an extended temperature range of -40°C to 105°C.

Pricing: $10.00 each in quantities of 100 (suggested resale pricing).
Availability: The DAC8881 is available now in a very small QFN-24 (4 x 4 mm) package. Evaluation modules (EVMs) will be available in 1Q 2008.
