What are the key features of TLC2254AQPWRG4Q1?
- AEC-Q100 automotive-qualified quad op-amp with rail-to-rail input and output enabling maximum signal swing in 3.3 V and 5 V vehicle systems
- Ultra-low 60 nA typical input bias current and 1 nA input offset current for precision measurement in high-impedance sensor interfaces
- Wide supply range of 1.4 V to 6 V single-supply with 83 dB typical CMRR, covering both 3.3 V microcontroller and 5 V automotive analog domains
What is TLC2254AQPWRG4Q1 used for?
TLC2254AQPWRG4Q1 is designed for automotive sensor signal conditioning, including throttle position, pressure sensor amplification, and current sensing in body control modules that require AEC-Q100 Grade 1 reliability. Its quad-channel rail-to-rail architecture allows four independent amplifier stages in a single 14-pin TSSOP, reducing PCB area in ADAS sensor front-ends and dashboard instrumentation circuits. The low 60 nA bias current is particularly valuable in capacitive sensor and pH electrode measurement applications within automotive environmental monitoring systems.

Frequently Asked Questions
What AEC-Q100 grade does TLC2254AQPWRG4Q1 carry and what does that mean for automotive designs?
TLC2254AQPWRG4Q1 is AEC-Q100 Grade 1 qualified, covering operation from -40°C to +125°C junction temperature with full electrical screening and reliability testing. This qualification is required by Tier 1 automotive suppliers for powertrain, chassis, and body control module applications where component failures have safety implications.
How does the 60 nA input bias current of TLC2254AQPWRG4Q1 benefit high-impedance sensor interfaces?
At 60 nA typical and 1 nA maximum input offset current at 25°C, TLC2254AQPWRG4Q1 introduces negligible loading error when connected to sensors with source impedances above 1 MΩ, such as pH electrodes, piezoelectric elements, or capacitive pressure sensors. This translates to less than 100 µV of input-referred offset error from bias current effects.
Can TLC2254AQPWRG4Q1 operate reliably from a 3.3 V microcontroller supply in automotive body electronics?
Yes. TLC2254AQPWRG4Q1 operates from 1.4 V to 6 V single supply, making it compatible with 3.3 V MCU analog domains. Its rail-to-rail output swings to within millivolts of both supply rails at 3.3 V, providing full signal range to ADC inputs in body control modules and ADAS sensor front-ends across -40°C to +125°C.
How many independent op-amp channels does TLC2254AQPWRG4Q1 provide and what package does it use?
TLC2254AQPWRG4Q1 integrates 4 independent op-amp channels in a 14-pin TSSOP package with 0.65 mm pitch, saving board space compared to using four single-channel op-amps. Each of the 4 channels supports rail-to-rail input and output with 83 dB typical CMRR and 70 dB minimum, supporting multi-channel sensor conditioning in a single small package.
