description

These devices are 8-bit successive-approximation analog-to-digital converters. The TLC0831 has single input

channels; the TLC0832 has multiplexed twin input channels. The serial output is configured to interface with

standard shift registers or microprocessors.

The TLC0832 multiplexer is software configured for single-ended or differential inputs. 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 any smaller analog voltage span to the full 8 bits of

resolution.

The operation of the TLC0831 and TLC0832 devices is very similar to the more complex TLC0834 and TLC0838

devices. Ratiometric conversion can be attained by setting the REF input equal to the maximum analog input

signal value, which gives the highest possible conversion resolution. Typically, REF is set equal to VCC (done

internally on the TLC0832).

The TLC0831C and TLC0832C are characterized for operation from 0°C to 70°C. The TLC0831I and TLC0832I

are characterized for operation from –40°C to 85°C.
