Radiation Hardened High Speed,
Monolithic Digital-to-Analog Converter
The HS-565BRH is a fast, radiation hardened 12-bit current
output, digital-to-analog converter. This part replaces the
HS-565ARH, which is no longer available. The monolithic
chip includes a precision voltage reference, thin-film R-2R
ladder, reference control amplifier and twelve high-speed
bipolar current switches.
The Intersil Corporation Dielectric Isolation process provides
latch-up free operation while minimizing stray capacitance
and leakage currents, to produce an excellent combination
of speed and accuracy. Also, ground currents are minimized
to produce a low and constant current through the ground
terminal, which reduces error due to code-dependent ground
currents.
HS-565BRH die are laser trimmed for a maximum integral
nonlinearity error of ±0.25 LSB at 25^oC. In addition, the low
noise buried zener reference is trimmed both for absolute
value and minimum temperature coefficient.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96755. A “hot-link” is provided
on our website for downloading.
