Dual 12-, 14-, and 16-bit DACs combine high precision, low power.August 26, 2011 -
Available in 3 x 3 mm QFN or 3 x 5 mm MSOP package options, DAC8562 series deliver precision with 0.1 nV-sec glitch energy, max offset error of 4 mV, max integral non-linearity (INL) of 0.75 LSB at 12-bits, and max reference drift of 10 ppm/°C. Integrated precision reference provides 20 mA sink/source capability, eliminating need for external buffer. Consuming 0.1 mA per channel, DACs support different control loops with options for both reset to zero-scale and reset to mid-scale.

TI's Family of Dual 16-, 14- and 12-bit DACs Provides Highest Precision, Lowest Power Consumption
DALLAS -- 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.
Tools and support
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.
Availability, packaging and pricing
Devices in the DAC8562 family are pin-for-pin compatible and are all available today in either a 3-mm x 3-mm QFN or 3-mm x 5-mm MSOP package. Pricing in 1,000-unit quantities is as follows:
-- 16-bit DAC8562 (reset to zero scale) and DAC8563 (reset to mid-scale) for $4.20.
-- 14-bit DAC8162 (reset to zero scale) and DAC8163 (reset to mid-scale) for $3.85.
-- 12-bit DAC7562 (reset to zero scale) and DAC7563 (reset to mid-scale) for $2.50.
