Product Summary
The TLC0832CDR is an 8-bit successive-approximation analog-to-digital converter. The TLC0832CDR has multiplexed twin input channels. The serial output is configured to interface with standard shift registers or microprocessors. The TLC0832CDR 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 TLC0832CDR device 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 TLC0832CDR).
