DAC337
Data Converter Line
Adjustment-Free 8-Bit DACs
FEATURES
• No Zero Or Gain Adjusts
• t/aLSB Linearity
• Internal Reference and Output Amplifier
• Low Power
DESCRIPTION
The DAC337 Series digital-to-analog converters are
designed for completely adjustment-free operation.
The word “ simplicity” best characterizes the DAC337
Series. All 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
linearity 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).
Spectrum Microwave offers the DAC337 for industrial and
commercial applications.

Operating
Storage
0ºC to +70ºC
–65ºC to +150ºC
Permanent damage may occur when unconnected devices are
subjected to high energy electrostatic fields. Unused devices must
be stored in conductive foam or shunts. Protective foam should be
discharged to the destination socket before devices are removed.
Devices should be-handled at static safe workstations only. Unused
digital inputs must be grounded or tied to the logic supply voltage.
Unless otherwise noted, the supply voltage at any digital input
should never exceed the supply voltage by more than 0.5 volts or
go betow –0.5 volts. If this condition cannot be maintained, limit
input current on digital inputs by using series resistors or contact
SatCon for technical assistance.
