DATEL DAC-HF8BME

The DAC-HF Series of hybrid DAC’s are ultra high-speed, current output devices. They incorporate state-of-the-art performance in a miniature package, achieving maximum output settling times of 25ns for the 8 and 10-bit models and 50ns for the 12-bit model. They can be used to drive a resistor load directly for up to ±1V output or a fast operational ampifier (such as DATEL’s AM-500) for higher voltage outputs with sub-microsecond settling times.
