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. 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.
