DESCRIPTION…
The
SP8481 Series
are complete monolithic data acquisition systems, featuring 8-channel
multiplexer, internal reference and 12-bit sampling A/D converter in 32–pin packages. Linearity
errors of
±
0.5 and
±
1.0 LSB, and Differential Non-linearity to 12-bits is guaranteed, with no
missing codes over temperature. Channel-to-channel crosstalk is typically -85dB. Multiplexer
settling plus acquisition time is 1.9
μ
s maximum; A/D conversion time is 8.1
μ
s maximum.
