DAC0830/DAC0832

8-Bit µP Compatible, Double-Buffered D to A Converters

General Description

Features

n Double-buffered, single-buffered or flow-through digital

data inputs

The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying

DAC designed to interface directly with the 8080, 8048,

8085, Z80^®, and other popular microprocessors. A deposited

silicon-chromium R-2R resistor ladder network divides the

reference current and provides the circuit with excellent

temperature tracking characteristics (0.05% of Full Scale

Range maximum linearity error over temperature). The cir-

cuit uses CMOS current switches and control logic to

achieve low power consumption and low output leakage

current errors. Special circuitry provides TTL logic input volt-

age level compatibility.

n Easy interchange and pin-compatible with 12-bit

DAC1230 series

n Direct interface to all popular microprocessors

n Linearity specified with zero and full scale adjust

only—NOT BEST STRAIGHT LINE FIT.

n Works with 10V reference-full 4-quadrant multiplication

n Can be used in the voltage switching mode

n Logic inputs which meet TTL voltage level specs (1.4V

logic threshold)

n Operates “STAND ALONE” (without µP) if desired

n Available in 20-pin small-outline or molded chip carrier

package

Double buffering allows these DACs to output a voltage

corresponding to one digital word while holding the next

digital word. This permits the simultaneous updating of any

number of DACs.

The DAC0830 series are the 8-bit members of a family of

Key Specifications

n Current settling time: 1 µs

™

microprocessor-compatible DACs (MICRO-DAC ).

n Resolution: 8 bits

n Linearity: 8, 9, or 10 bits (guaranteed over temp.)

n Gain Tempco: 0.0002% FS/˚C

n Low power dissipation: 20 mW

n Single power supply: 5 to 15 V_DC
