description
These devices are 8-bit successive-
approximation analog-to-digital converters, each
with an input-configurable multichannel
multiplexer and serial input/output. The serial
input/output is configured to interface with
standard shift registers or microprocessors.
Detailed information on interfacing with most
popular microprocessors is readily available from
the factory.

The TLC0834 (4-channel) and TLC0838 (8-channel) multiplexer is software configured for single-ended or
differential inputs as well as pseudo-differential input assignments. The differential analog voltage input allows
for common-mode rejection or offset of the analog zero input voltage value. In addition, the voltage reference
input can be adjusted to allow encoding of any smaller analog voltage span to the full 8 bits of resolution.
The TLC0834C and TLC0838C are characterized for operation from 0°C to 70°C. The TLC0834I and TLC0838I
are characterized for operation from – 40°C to 85°C. The TLC0834Q is characterized for operation from – 40°C
to 125°C.
