What are the key features of TLC2254AQDR?
- Rail-to-rail output swing within millivolts of supply rails enabling full dynamic range on ±8 V or 1.4 V to 16 V single supply
- 1 pA typical input bias current for accurate buffering of high-impedance sensors and pH electrodes without significant offset
- 83 dB typical common-mode rejection ratio supporting precision differential signal conditioning in noisy automotive environments
- Automotive-grade qualification across -40°C to +125°C for reliable in-vehicle sensor interface and body electronics applications
What is TLC2254AQDR used for?
The TLC2254AQDR is used in automotive sensor signal conditioning, battery management analog front-ends, and precision instrumentation where four amplifier channels must process high-impedance signals from resistive bridges, thermistors, or electrochemical sensors. Its rail-to-rail output stage maximizes signal swing when running from a single 5 V supply in space-constrained ECU designs. The automotive temperature qualification and SOIC-14 T/R packaging make it cost-effective for medium-volume production of cabin control modules and powertrain sensor nodes.
