DAC1218 Datasheet 12-bit Binary Multiplying D/a Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DAC1218 DAC1219 12-Bit Binary Multiplying D A Converter December 1994 DAC1218 DAC1219 12-Bit Binary Multiplying D A.

General Description

The DAC1218 and the DAC1219 are 12-bit binary 4-quadrant multiplying D to A converters The linearity differential non-linearity and monotonicity specifications for these converters are all guaranteed over temperature In addition these parameters are specified with standard zero and fullscale adjustment procedures as opposed to the impractical best fit straight line guarantee This level of precision is achieved though the use of an advanced silicon-chromium (SiCr) R-2R resistor ladder network This type of thin-film resistor eliminates the parasitic diode problems associated with diffused resistors and allows the applied reference voltage to range from b25V to 25V independent of the logic supply voltage CMOS current switches and drive circuitry are used to achieve low power consumption (20 mW typical) and minimize output leakage current errors (10 nA maximum) Unique digital input circuitry maintains TTL patible input threshold voltages over the full operating supply voltage range The DAC1218 and DAC1219 are direct replacements for the AD7541 series AD7521 series and AD7531 series with a significant improvement in the linearity specification In applications where direct interface of the D to A converter to a microprocessor bus is desirable the DAC1208 and DAC1230 series eliminate the need for additional interface logic
