GENERAL DESCRIPTION
The SPT7830 10-bit, 2.5 MSPS, serial analog-to-digital
converter delivers excellent high speed conversion perfor-
mance 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
2.5 MSPS.

APPLICATIONS
• Handheld and Desktop Scanners
• DSP Interface Applications
• Portable Digital Radios
• Portable and Handheld Applications
• Automotive Applications
• Remote Sensing
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 hand-held appli-
cations where board space is at a premium. The SPT7830 is
available in an 8-lead SOIC package over the commercial
and industrial temperature ranges. Contact the factory for
availability of die.
