HS1-565ARH

Semiconductor HS-565ARH Radiation Hardened High Speed, Monolithic Digital-to-Analog Converter Description The HS-565ARH is a fast, radiation hardened 12-bit current output, 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 nonlinearity error of ±0.25 LSB at +25oC. In addition, the low noise buried zener reference is trimmed both for absolute value and minimum temperature coefficient.
