GENERAL DESCRIPTION
The SPT7851 10-bit, 20 MSPS analog-to-digital converter
has a pipelined converter architecture built in a CMOS pro-
cess. It delivers high performance with a typical power dissi-
pation of only 79 mW. With low distortion and high dynamic
range, this device offers the performance needed for imag-
ing, multimedia, telecommunications and instrumentation
applications.
The SPT7851 is available in a 44-lead Thin Quad Flat Pack
(TQFP) package in the industrial temperature range (–40 °C
to +85 °C).
