description
These devices are 8-bit successive-approximation
analog-to-digital
converters,
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 TLV0834 (4-channel) and TLV0838 (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.
