HI-565A
Data Sheet June 1999 File Number 3109.2
High Speed, Monolithic D/A Converter with Reference
The HI-565A is a fast, 12-bit, current output, digital-to-analog converter. The monolithic chip includes a precision voltage reference, thin-film R2R ladder, reference control amplifier and twelve high speed bipolar current switches. The Intersil dielectric isolation process provides latch 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. HI-565A dice are laser trimmed for a maximum integral nonlinearity error of ±0.5 LSB at 25oC.
