Texas Instruments (TI) has launched the DAC8562 family of dual 12-, 14- and 16- bit digital-to-analog converters (DACs). The DACs can be used in portable medical devices, laser modules, and wireless base stations.
DAC8562 Family - Dual 16/14/12-Bit Precision DACs
The 8562 DACs consume low power and provide high precision. They are ultra-small, allowing them to be used in space-constrained systems. The low power consumption allows them to be applied in power-constrained systems, including precision instrumentation, portable medical equipment, programmable logic control analog output modules, wireless base stations and motor control. When compared to other similar devices, the DAC8562 family provides a 60% lower offset error and 25% better integral non-linearity (INL).
TI’s DAC8562 family consumes 0.1 mA of power per channel and allows it to be used for operating portable medical devices, CNC machines, tunable laser modules and in wireless base stations. It provides high precision in its class with glitch energy of 0.1 nV-sec, and 0.75 LSB at 12-bits INL. The DACs have a 10 ppm/°C of maximum reference drift and a 4 mV maximum offset error.
The DAC8562 family has options for resetting to mid-scale and zero-scale, allowing greater flexibility in design to support various types of control loops. It is designed for severe industrial environments with temperatures of up to 125°C. The DACs have an integrated precision reference that reduces board space and cost. The reference eliminates the necessity of an external buffer by providing a 20-mA sink/source capability.
The company is offering support and tools, at no cost, for development of products with the DAC family. An IBIS model, reference designs, and evaluation modules are among the tools being offered.
