HI-565A
FN3109.4
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 25^oC. In addition, the low
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.
