Description

The SPT7937 is a 12-bit monolithic, low-cost, low-power analog-to-digital converter capable of minimum sample rates of 28 MSPS. The SPT7937 has incorporated propri-etary parallel SAR circuit design and CMOS processing technologies to achieve its advanced performance.The on-chip track-and-hold function assures very good dynamic performance without the need for external components.

Power dissipation is extremely low at only 170 mW typical at 28 MSPS with a power supply of +5.0 V. The digital outputs are +3 V or +5 V, and are user selectable.  Inputs and out-puts are TTL/CMOS compatible to interface with TTL/CMOS logic systems. Output data format is straight binary.

The SPT7937 is available in a 28-lead SSOP package over the industrial temperature range.
