HI-565A

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

noise buried zener reference is trimmed both for absolute

value and temperature coefficient. Power dissipation is

typically 250mW, with

±15V supplies.

The HI-565A is offered in both commercial and military

grades. See Ordering Information.
