PRODUCTDESCRIPTION
TheAD1408 and AD1S08 are low cost monolithic integrated
circUit8-bit multiplying digital-to-analog converters, consisting
ofmatched bipolar switches, a precision resistor netWork and a
controlamplifier. The single chip is mounted in a hermetically
sealedceramic 16 lead dual-in-line package.

PRODUCT HIGHLIGHTS
1. Monolithic IC construction makes the AD 1408/AD1S08 an
optimum choice for applications where low cost is a major
consideration.
2. The AD1408/AD1S08 directly replaces other devices of
this type.
3. Versatile design configuration allows voltage or current out-
puts, variable or fixed reference inputs, CMOS or TTL
logic compatibility and a wide choice of accuracy and tem-
peratUre range specifications.
4. Accuracies within :t%LSB allow performance improvement

deviceshave been designed in. The AD14O8 series is specified
for operation over the 0 to +7SoC temperature range, the
ADlS08 series for operation over the entire militaty tempera-
tUrerange of -SSoC to +12SoC.
7. The AD1408/AD1S08 multiplies in tWo quadrants when a
varying reference voltage is applied. When multiplication is
not required, a fixed reference is used.
8. The AD1408/AD1S08 is available in chip form; please con-
sult factory for details.
9. The device is packaged in a hermetically-sealed ceramic 16
lead dual-in-line package. Processing to MIL-STD-883 level
B is available.
