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

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