Datel has announced the DAC-12100 series of low power 12-bit current output digital to analogue converters that have TTL/CMOS compatible inputs. With a 100 MHz conversion rate, these ultra-high speed devices suit any speed critical applications such as radar, signal reconstruction, waveform generators and communications equipment.
With an extremely low glitch energy characteristic of 3.0 pV-s compared to the industry norm of 100 pV-s, the DAC-12100 generates very little switching noise. The complementary current outputs of 0 to -20.48 mA can directly drive 50 ohm loads. Dynamic performance, to Nyquist at fOUT of 2.02 MHz, provides a spurious free dynamic range (SFDR) specification of – 85 dB.
