GENERAL DESCRIPTION

The SPT7830 10-bit, 2.5 MSPS, serial analog-to-digital converter 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 2.5 MSPS.
