GENERAL DESCRIPTION
The Fairchild 8-bit, 3.0 MSPS, serial analog-to-digital con-
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.
