DescriptionThe 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 iscompatible with the serial peripheral interface (SPI) orMICROWIRE™ industry standard, high-speed synchronous MPU interfaces. The large input bandwidth and fast transientresponse time of the SPT7730 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 for handheld applications where board space is a premium.The SPT7730 is available in an 8-lead SOIC package over the commercial temperature range.Contact the factory for availability of die and industrial temperature range versions.
