12-Bit A/D Converter with 3-State Binary Outputs
General Description
The ICL7109 is a monolithic 12 bit A/D converter
designed for easy interface with microprocessors
and UARTs. The 12 bit binary plus polarity and over-
range outputs can be directly interfaced to a micro-
processor bus. In this modethe ICL7109 is controlled
by the microprocessor through the chip select and
two byte enable inputs. For remote data logging
applications the ICL7109 outputs are easily converted
to a UART handshake mode, working with industry
standard UARTs to provide serial data transmission.
This device offers high accuracy by lowering rollover
error to less than 1 count and zero reading drift to
less than 1 pV/°C. In many data acquisition systems
the ICL7109 is an attractive, low cost, one-per-
channel alternative to analog multiplexing due to
its low power consumption and input bias current.
Maxim has added a zero-integrator phase to the
ICL7109, eliminating overrange hangover, "Crosstalk"
and hysteresis effects. Maxim has also increased the
current sourcing capabilities of the ICL7109, enabling
it to rapidly drive the large capacitances often found
on microprocessor busses.

Note 1: Input voltages may exceed the supply voltages, provided the input current is limited to $100 p.
Note 2: Due to the SCR structure inherent in the process used to fabricate these devices. connecting any digital inputs or outputs to
voitagesgreaterthan V+ orless than GND may cause destructive device Iatchup. Forthis reason it is r.ec.omnytnpt!d that no inputs
from. sources other than the same power supply be applied to the ICL7109 before its power supply Is established, and that in
multiple supply systems the supply to the ICL7109 be activated first.
Note 3: This limit refers to that of the package and will not be obtained during normal operation.
