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.
