• t/aLSB Linearity

• Internal Reference and Output A mplifier

• Low Power

DESCRIPTION

The DA C337 Series digital-to-analog converters are

designed for completely adjustment-free operation.

The word “ simplicity” best characterizes the DA C337

Series. A ll models are housed in hermetically sealed

DIP style packages and operate on ±15V power

supplies. Each model incorporates a precision

reference, highly stable thin-film nichrome resistor

network, output amplifier, and switches. ±1/2 LSB

li nearity is achieved without the use of external zero

and gain adjustment circuits.

Four output voltage ranges are offered — 0 to +10,

0 to –10 (unipolar) and ±5, ±10 (bipolar).
