SPT7830 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 protocols 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.
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.

SPT7835 General Description
The SPT7835 is a 10-bit monolithic, low-cost, ultralow-power analog-to-digital converter capable of minimum word rates of 5 MSPS. The on-chip track-and-hold function assures very good dynamic performance without the need for external components. The input drive require-ments are minimized due to the SPT7835's low input capacitance of only 5 pF.
Power dissipation is extremely low at only 75 mW typical at 5 MSPS with a power supply of +5.0 V. The digital out-puts are +3 V or +5 V, and are
user selectable.The SPT7835 is pin-compatible with an entire family of 10-bit,CMOS converters (SPT7835/40/50/55/60/61), which sim-plifies The SPT7835 has incorporated propri-etary circuit design* and CMOS processing technologies to achieve its advanced performance. Inputs and outputs
are TTL/CMOS-compatible to interface with TTL/CMOS logic systems. Output data format is straight binary.
The SPT7835 is available in a 28-lead SOIC package over the industrial temperature range, and a 32-lead small(7 mm square) TQFP package over the commercial temperature range.
