Datel has announced the DAC-12100 series of 12bit current output DACs that have transistor-transistor logic and CMOS compatible inputs. With a 100MHz conversion rate, the converters are suitable for radar, signal reconstruction, waveform generators and communications equipment. The complementary current outputs of 0 to -20.48mA can directly drive 50Ω loads. Dynamic performance, to Nyquist at fOUT of 2.02MHz, provides a free dynamic range specification of -85dB. The converters use a R/2R resistor network and a segmented switching current cell arrangement in order to reduce glitch energy, says the company. They are available in a hermetically sealed 28pin ceramic leadless chip carrier solder dipped leads package measuring 11.43x11.43mm. They operate from -55 to +125°C and meet all MIL-PRF-38534 standard requirements.
