HS-565BRH
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
o
C. 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
