MAXIM INTEGRATED PRODUCTS  MAX507BCWG+  数模转换器, 精准, 12 bit, 双极性、单极性, ± 11.4V 至 ± 15.75V, WSOIC, 24 引脚

The is a voltage output, 12bit digital to analogue converter DAC with internal reference in 24 pin WSOIC package. This DAC"s output voltage has same polarity as reference, the basic circuit consists of a laser trimmed, thin-film, R-2R resistor array with NMOS switches. The double buffered logic inputs interface easily to µPs, data is transferred into input register either from a 12bit wide data bus or 16bit µPs. All logic signals are level triggered, TTL & CMOS compatible. Interface timing specifications insure compatibility with all common µPs. DAC is specified & tested for both dual & single supply operation. Usable supplies range from single +12V to dual ±15V. On-board gain-setting resistors allow three output-voltage ranges, 0V to +5V and 0V to +10V can be generated when using either single or dual supplies. With dual supplies, ±5V is also available. This is used in arbitrary function waveform generators, automated calibration, digital offset and gain adju
