8-Bit Multiplying Digital-to-Analog Converter
Description
The HA17408P is an 8-bit monolithic D/A converter that incorporates a reference current amplifier, an R-2R
resistor ladder, and eight high-speed current switches.
Circuit designers can set the maximum output current to match the needs of their applications by setting the
reference voltage and selecting a resistor value.
The reference current is distributed to the current value for each bit by the R-2R resistor ladder, and thus the
maximum output current is 255/256 times the reference current. For example, the largest output current that
can be acquired for a reference input current of 2.0 mA is 1.992 mA.
The HA17408P can be used in a wide range of applications including CRT displays, stepping motor control,
programmable power supplies, audio equipment, and attenuators.
