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

ied zener reference is trimmed both for absolute value and mini-

mum temperature coefficient.
