PRODUCT OVERVIEW

INPUT/OUTPUT CONNECTIONS

The DAC-88 Series D/A converters are high

pin programmable and include 0 to +10V, ±±V,

and ±10V. The DAC-88 Series contains a precision

zener reference circuit. This eliminates code-

dependent ground currents by routing current from

the positive supply to the internal ground node

as determined by the R-2R ladder network. The

internal feedback resistors for the on-board ampli-

ﬁer track the ladder network resistors, enhancing

temperature performance. The excellent tracking

of the resistors results in a differential nonlinearity

tempco of ±2ppm/ꢀC maximum. The temperature

coefﬁcient of gain is ±20ppm/ꢀC maximum, and

the tempco of zero is ±±ppm/ꢀC maximum.

PIN FUNCTION

performance 12-bit devices with a fast settling

voltage output. They are compatible and pin-pin

replacement for the standard DAC88 and 3860

series. They incorporate a level-controlled input

storage register and are speciﬁcally designed for

systems applications such as data bus interfacing

with computers. When the “load/Register Enable”

input is high, data in the storage register is held,

and when the load input is low, data is transferred

through to the DAC. There are two basic models

available by coding option: binary and two’s com-

plement. The output voltage ranges are externally
