GENERAL DESCRIPTION

verter delivers excellent high speed conversion performance

with low cost and low power. The serial port protocol is

compatible with the serial peripheral interface (SPI) or

MICROWIRE™ industry standard, high-speed synchronous

MPU interfaces. The large input bandwidth and fast transient

response time allow for CCD applications operating up to

3.0 MSPS.

The device can operate with a power supply range from +3 V

to +5 V with very low power dissipation. The small package

size makes this part excellent for handheld applications

where board space is a premium. The SPT7730 is available

in an 8-lead SOIC package over the commercial tempera-

ture range. Contact the factory for availability of die and

industrial temperature range versions.
