GENERAL DESCRIPTION
The SPT7725 is a monolithic flash A/D converter capable
of digitizing a two volt analog input signal into 8-bit digital
words at a 300 MSPS (typ) update rate.
For most applications, no external sample-and-hold is re-
quired for accurate conversion due to the device’s narrow
aperture time, wide bandwidth, and low input capacitance.
A single standard –5.2 volt power supply is required for
operation of the SPT7725, with nominal power dissipation
of 2.2 W. A proprietary decoding scheme reduces meta-
stable errors to the 1 LSB level.
The SPT7725 is available in 42-lead ceramic sidebrazed
DIP, surface-mount 44-lead cerquad, and 46-lead PGA
packages (all are pin-compatible with the SPT7710); the
cerquad and PGA packages allow access to additional
reference ladder taps, an overrange bit, and a data ready
output. The SPT7725 is available in the industrial tem-
perature range.
