Texas Instruments Inc. introduced a family of dual 16-, 14- and 12-bit digital-to-analog converters (DACs) that it says provides the industry's highest precision and lowest power consumption.
According to TI, 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, according to TI.
- 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.
