DESCRIPTION…

The SP8480 Series are complete monolithic data acquisition systems, featuring 8-channel

multiplexer, internal reference and 12-bit sampling A/D converter in 28–pin plastic DIP or SOIC

packages. Linearity errors of

±0.5 and ±1.0 LSB, and Differential Non-linearity to 12-bits are

guaranteed, with no missing codes over temperature. Multiplexer settling plus acquisition time

is 1.9

µs maximum; A/D conversion time is 8.1µs maximum.
