AD667AD

AD667 is a complete voltage output 12bit digital to analog converter including a high stability buried zener voltage reference and double buffered input latch on a single chip. The converter uses 12 precision high speed bipolar current steering switches and a laser trimmed thin film resistor network to provide fast settling time and high accuracy. The subsurface zener diode on the chip provides a low noise voltage reference which has a long term stability and temperature drift characteristics comparable to the best discrete reference diodes. The laser trimming process which provides excellent linearity, is also trim the absolute value of the reference as well as its temperature coefficient.
