Features
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.
• Devices QML Qualified in Accordance with
MIL-PRF-38535
• Detailed Electrical and Screening Requirements
are Contained in SMD# 5962-96755 and Harris’ QM
Plan
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
• DAC and Reference on a Single Chip
• Pin Compatible with AD-565A and HI-565A
• Very High Speed: Settles to 0.50 LSB in 500ns Max low and constant current through the ground terminal, which
reduces error due to code-dependent ground currents.
• Monotonicity Guaranteed Over Temperature
HS-565ARH die are laser trimmed for a maximum integral nonlin-
earity error of ±0.25 LSB at +25oC. In addition, the low noise bur-
