描述 Description

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 full scale 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 al lows the applied reference voltage to range from b25V to 25V, independent of the logic supply voltage.

特性 Features

■ Linearity specified with zero and full-scale adjust only
■ Logic inputs which meet TTL voltage level specs (1.4V logic threshold)
■ Works with g10V referenceDfull 4-quadrant multiplication
■ All parts guaranteed 12-bit monotonic?
