General description
the adc0801, adc0802, adc0803, adc0804 and
adc0805 are cmos 8-bit successive approximation a/d
converters that use a differential potentiometric ladderð
similar to the 256r products. these converters are designed
to allow operation with the nsc800 and ins8080a
derivative control bus with tri-stateé output latches directly
driving the data bus. these a/ds appear like memory
locations or i/o ports to the microprocessor and no interfacing
logic is needed.
differential analog voltage inputs allow increasing the common-
mode rejection and offsetting the analog zero input
voltage value. in addition, the voltage reference input can
be adjusted to allow encoding any smaller analog voltage
span to the full 8 bits of resolution.
