Texas Instruments Incorporated (TI) (NYSE: TXN) today
introduced a family of dual 16-, 14- and 12-bit digital-to-analog converters
(DACs) that provides the industry’s highest precision and lowest power
consumption. The DAC8562 family delivers 25-percent better integral
non-linearity (INL) and 60-percent lower offset error compared to similar
devices. The DACs also provide best-in-class power consumption and are
ultra-small, making them suitable for space and power-constrained systems, such
as wireless base stations, programmable logic control (PLC) analog output
modules, motor control, precision instrumentation and portable medical
equipment.
Key features and benefits of the DAC8562 family
- Best-in-class precision with 0.1 nV-sec glitch energy, a
maximum offset error of 4 mV, a maximum INL of 0.75 LSB at 12-bits and a
maximum reference drift of 10 ppm/degree C improves system accuracy. - Lowest power consumption in its class, consuming only 0.1 mA
per channel to minimize the power required for VGA control in wireless base
stations, as well as to operate tunable laser modules, CNC machines and
portable medical devices, such as oscilloscopes and portable blood analyzers. - Reduces cost and board space with an integrated precision
reference that provides a 20-mA sink/source capability to eliminate the need
for an external buffer. - Supports different control loops with options for both reset
to zero-scale and reset to mid-scale to provide greater design flexibility. - Characterized for harsh industrial environments up to 125
degrees Celsius, 20 degrees higher than the competition.
TI offers a variety of free tools and support to speed
development with the DAC8562 family, including:
- Two evaluation modules for quick evaluation. The DAC8562EVM
and DAC7562EVM are available today for
a suggested retail price of $49. - An IBIS model to verify board signal
integrity requirements. - Reference designs for analog output modules in PLCs and
high-voltage, bipolar output control applications, which are included in the
DAC8562 data sheet.
