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.

Features

A linearity of ±0.19% (± 1/2 LSB) is guaranteed.

Short centering time (250 ns typical) for rapid conversions

Low power dissipation: 157 mW typical

Compatible with TTL and CMOS logic

Standard supply voltages of V

Wide output voltage range: +0.5 to –5.0 V

8-Bit Multiplying Digital-to-Analog Converter

= +5.0 V, V
