Radiation Hardened High Speed, Monolithic
Digital-to-Analog Converter
HS-565BRH, HS-565BEH
Features
The HS-565BRH, HS-565BEH are fast, radiation hardened
12-bit current output, digital-to-analog converters. This part
replaces the HS-565ARH, which is no longer available. The
monolithic chips include a precision voltage reference,
thin-film R-2R ladder, reference control amplifier and twelve
high-speed bipolar current switches.
• Electrically Screened to SMD # 5962-96755
• QML Qualified per MIL-PRF-38535 Requirements
• Total Dose . . . . . . . . . . . . . . . . . . . . . . . . . . 100 krad (Si) (Max)
• 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
• Monotonicity Guaranteed Over Temperature
• 0.50 LSB Max Nonlinearity Guaranteed Over Temperature
The Intersil 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.
• Low Gain Drift
(Max., DAC Plus Reference) . . . . . . . . . . . . . . . . . . 50ppm/°C
HS-565BRH, HS-565BEH die are laser trimmed for a
• ±0.75 LSB Accuracy Guaranteed Over Temperature
(±0.125 LSB Typical at +25°C)
maximum integral nonlinearity error of ±0.25 LSB at +25°C. In
addition, the low noise buried zener reference is trimmed both
for absolute value and minimum temperature coefficient.
Applications
• High Speed A/D Converters
• Precision Instrumentation
• Signal Reconstruction
