SP8481 Series* Monolithic, 12–Bit Data Acquisition System s Complete Monolithic 8-Channel, 12-Bit DAS s 100kHz Throughput s 16-Bit Microprocessor Bus Interface s Latched MUX Address s All-channel Deselect s 8/4-Bit Nibble Output s No Missing Codes to 12-Bits s 32-Pin Packages s 200mW Max Power Dissipation * Formerly part of the SP410 Series. 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 1.9µs maximum; A/D conversion time is 8.1µs maximum. MULTIPLEXER 12-BIT A/D CONVERTER MUX DECODE ADD.
