TI Introduces Family of High-Precision Dual DACs
Texas Instruments Inc. (TI) introduced a family of high-precision dual 16-, 14- and 12-bit digital-to-analog converters (DACs). According to the company, the DAC8562 family delivers 25% better integral non-linearity (INL) and 60% lower offset error compared to similar devices. The DACs also provide reduced 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.
Features of the DAC8562 family are: 0.1nV-sec glitch energy, a maximum offset error of 4mV, a maximum INL of 0.75 LSB at 12-bits and a maximum reference drift of 10 ppm/°C improves system accuracy; Consume only 0.1mA 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 20mA 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; and characterized for harsh industrial environments up to 125°C.
