The HS 3860 includes an internal precision reference supply, a fast output amplifier for minimum settling time, and input registers for easier microprocessor interface. The D/A is constructed using hybrid microcircuit technology and includes a precision thin-film network, laser-trimmed to produce a high linearity, high accuracy converter, stable over a wide temperature range. Errors in linearity and accuracy are specified at room temperature as well as operating temperature extremes for both military and commercial products. M IL-STD-883 Rev. C, Level B screening and processing is available in the “ B” grade device. Operating temperature range for the HS 3860B is – 55ºC to +125ºC.

The analog output follows the digital input when Register Enable is a logic “ 0” . The analog output is constant when the Register Enable is a logic “ 1” . 2. SatCon guarantees and tests maximum Linearity Error at the extremes of the operating temperature and at room temperature. ±1/2 LSB Linearity Error guarantees monotonicity and differential linearity of ±1 LSB. 3. One LSB is 0.024% F.S.R. for a 12 bit DA C. 4. F.S.R. is Full Scale Range. For the ± 10V output range the F.S.R. is 20 volts and 1 LSB is 4.88mV . 5. A bsolute A ccuracy Error includes linearity, gain, offset and all other errors and is specified without the use of adjustments. 6.
