MAX161

The MAX161 is a kind of CMOS single-chip 8-bit,8-channel data acquisition systems(DAS).Each chip includes an 8-bot A/D converter,8-channel multiplexer,8x8 dual port RAM with contention logic,and microprocessor compatible I/O logic.

Features of the MAX161 are:(1)fast conversion time; (2)no missing codes over temperature; (3)on chip 8 x 8 dual port RAM; (4)interfaces directly to Z80/8085/6800; (5)ratiometric capability; (6)interleaved DMA operaiton.

The absolute maximum ratings of the MAX161 can be summarized as:(1): VDD to AGND is +7 V; (2): VDD to DGND is +7 V; (3): AGND to DGND is -0.3 V to VDD; (4): digital input voltage to DGND is -0.3 V to VDD(pins 13,16 to 19); (5): digital output voltage to DGND is -0.3 V to VDD(pins 12,20 to 27); (6): Vref(pin 10) to AGND is +/-25 V; (7): AIN(0 to 7 , pins 9 to 2) is +/- 17 V.
