HS-565ARH
Radiation Hardened High Speed,
Monolithic Digital-to-Analog Converter
Description
The HS-565ARH is a fast, radiation hardened 12-bit current out-
put, digital-to-analog converter. The monolithic chip includes a
precision voltage reference, thin-film R-2R ladder, reference
control amplifier and twelve high-speed bipolar current
switches.
The Harris Semiconductor 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-565ARH die are laser trimmed for a maximum integral nonlin-
earity error of
±0.25
LSB at +25
o
C. In addition, the low noise bur-
ied zener reference is trimmed both for absolute value and mini-
mum temperature coefficient.
