GENERAL DESCRIPTION
The SPT7935 12-bit, 20 MSPS analog-to-digital converter
has a pipelined converter architecture built in a CMOS
process. It delivers high performance with a typical power
dissipation of only 79 mW. With low distortion and high
dynamic range, this device offers the performance needed
for imaging, multimedia, telecommunications and instrumen-
tation applications.
The SPT7935 is available in a 44-lead Thin Quad Flat Pack
(TQFP) package in the industrial temperature range (–40 to
+85
°
C).
