DESCRIPTION
The HS 3860 is a 12-Bit digital-to-analog converter
packaged in a hermetically sealed 24-pin doublewidth, dual-in-line package.
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.

NOTES
1. 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. Commercial M odels are specified over a temperature range of 0ºCto+70ºC.
