A8-DBCit0µ8SP0h1Ce/AoeDmt4CpU0a.8cti0ob2mle/AAD/CD0C80o3n/vAeDrtCe0rs804/ADC0805General Description
taThe ADC0801, ADC0802, ADC0803, ADC0804 and
aADC0805 are CMOS 8-bit successive approximation A/D
converters that use a differential potentiometric
.Dladder — similar to the 256R products. These converters are
wdesigned to allow operation with the NSC800 and INS8080A
derivative control bus with TRI-STATE output latches directly
w driving the data bus. These A/Ds appear like memory loca-
w tions or I/O ports to the microprocessor and no interfacing
mlogic is needed.
Differential analog voltage inputs allow increasing the
ocommon-mode rejection and offsetting the analog zero input
voltage value. In addition, the voltage reference input can be
.cadjusted to allow encoding any smaller analog voltage span
to the full 8 bits of resolution.
