General Description
The MAX180/MAX181 are complete12-bitData Acquisition
System (DAS) which combine 8/6-channel input multi-
plexer, high bandwidth Track-and-Hold (T/H), low-drift
zener reference, and flexible microprocessor (pP) interface
with high conversion speed and low power consumption.
The MAX180NAX181 can be configured by a " for
unipolar or bipolar conversions and single-ended or differ-
ential inputs. Both devices sample and digitize at 100kHz
throughput rate and feature a fast 8- or 16-bit pP interface.
The MAX180 has 8 analog input channels, while the MAX181
has 6. The multiplexer output of the MAX180 is fed directly
into the Analog-to-Digital Converter (ADC) input. The
MAX181 bringsout both the multiplexer output and ADC input
to separate pins, allowing a programmable gain amplifier to
be inserted between the MUX and the ADC.
The systems allow the user to choose between an internal
or an external reference, Futhermore, the internal refer-
ence value and the offset can be adjusted, allowing the
overall system gain and offset errors to be nulled. The
multiplexer has high impedance inputs, simplifying ana-
log drive requirements.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sechons of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect de vice reliability.
