PRODUCT OVERVIEW

INPUT/OUTPUT CONNECTIONS

The DAC-HK Series hybrid D/A converters are

highperformance 12-bit devices with a fast settling reference circuit. This eliminates code-dependent

voltage output. They incorporate a level-controlled ground currents by routing current from the

input storage register and are speciﬁcally designed positive supply to the internal ground node as

for systems applications such as data bus interfac- determined by the R-2R ladder network. The

The DAC-HK Series contains a precision zener

ing with computers. When the “load” 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 complement. The

output voltage ranges are externally pinprogram-

mable and include: 0 to +5V, 0 to +10V, 2.5V,

5V and 10V.

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 5ppm/ꢀC maximum.
