TI Unveils Industry's Smallest 16-Bit DAC for Portable Instrumentation and Industrial Control
Miniature device provides excellent price/performance value for precision data conversion
TUCSON, Ariz. (Apr. 12, 2001) -- Texas Instruments Incorporated (TI) (NYSE: TXN) today announced a new 16-bit digital-to-analog converter (DAC) from the company's Burr-Brown product line, featuring miniature package size and low power operation. This cost-effective data converter targets high-performance systems found in industrial process control, data acquisition, and portable instrumentation. See http://www.ti.com/sc/aap6140u.
The DAC8531's small footprint, wide supply voltage and low power consumption - 250 micro amps (uA) at 5V - make it ideal for portable battery-operated applications. It also features a power-down mode that reduces current consumption to 1 uA (max).
"By providing high resolution and low power in an MSOP package, TI offers designers a price/performance solution unmatched in the DAC market," said Zack Albus, strategic marketing for TI's data acquisition products. "The DAC8531 also provides customers with an easy performance upgrade path for previous generations of pin-compatible 12-bit DACs."
The DAC8531 is optimized for closed-loop feedback systems requiring monotonicity and a fast host control interface. A power-on-reset circuit ensures that the DAC output powers up at zero volts and remains there until a valid write takes place. An on-chip precision output amplifier allows rail-to-rail output performance.
The device uses a versatile three-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPI™, QSPI™, and Microwire™ interfaces, as well as TI's TMS320 DSPs. Key features include single 2.7V to 5.5V supply operation, guaranteed 16-bit monotonic performance, and 10 us settling time (0.003% accuracy).
Available Today
The DAC8531 is available now and is packaged in an MSOP-8. It is priced from $3.75 in 1,000 piece quantities.
