ADC0801/ADC0802/ADC0803/ADC0804/ADC0805
8-Bit μP Compatible A/D Converters
General Description
The
ADC0801,
ADC0805 are CMOS 8-bit successive approximation A/D
converters
that
use
a
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 di-
rectly driving the data bus. These A/Ds appear like memory
locations or I/O ports to the microprocessor and no interfac-
ing 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.
ADC0802,
ADC0803,
ADC0804
and
differential
potentiometric
