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 TLV0834 (4-channel) and TLV0838 (8-channel) multiplexer is software-configured for single-ended or
differential inputs as well as pseudodifferential 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 TLV0834C and TLV0838C are characterized for operation from 0°C to 70°C. The TLV0834I and TLV0838I
are characterized for operation from – 40°C to 85°C.
