DESCRIPTION
The ADC0801, ADC0802, ADC0803, ADC0804 and
ADC0805 are CMOS 8-bit successive approximation
A/D converters that use a differential potentiometric
ladder — similar to the 256R products. These
converters are designed to allow operation with the
NSC800 and INS8080A derivative control bus with
TRI-STATE 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.
