DAC0800/DAC0801/DAC0802 8-Bit Digital-to-Analog Converters

January 1995

DAC0800/DAC0801/DAC0802 8-Bit Digital-to-Analog
Converters

General Description

The DAC0800 series are monolithic 8-bit high-speed cur­rent-output digital-to-analog converters (DAC) featuring typi­cal settling times of 100 ns. When used as a multiplying
DAC, monotonic performance over a 40 to 1 reference cur­rent range is possible. The DAC0800 series also features
high compliance complementary current outputs to allow
differential output voltages of 20 Vp-p with simple resistor
loads as shown in

Figure 1

. The reference-to-full-scale cur-

rent matching of better than

g

1 LSB eliminates the need for
full-scale trims in most applications while the nonlinearities
of better than

g

0.1% over temperature minimizes system

error accumulations.

The noise immune inputs of the DAC0800 series will accept
TTL levels with the logic threshold pin, V

LC

, grounded.

Changing the V

LC

potential will allow direct interface to oth­er logic families. The performance and characteristics of the
device are essentially unchanged over the full

g

4.5V to

g

18V power supply range; power dissipation is only 33 mW

with

g

5V supplies and is independent of the logic input

states.

The DAC0800, DAC0802, DAC0800C, DAC0801C and
DAC0802C are a direct replacement for the DAC-08, DAC­08A, DAC-08C, DAC-08E and DAC-08H, respectively.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.

Note 2: The maximum junction temperature of the DAC0800, DAC0801 and DAC0802 is 125

§

C. For operating at elevated temperatures, devices in the Dual-In-Line

J package must be derated based on a thermal resistance of 100

§

C/W, junction-to-ambient, 175§C/W for the molded Dual-In-Line N package and 100§C/W for the

Small Outline M package.

Note 3: Human body model, 100 pF discharged through a 1.5 kX resistor.

Note 4: Pin-out numbers for the DAC080X represent the Dual-In-Line package. The Small Outline package pin-out differs from the Dual-In-Line package.
