What the key ratings mean for the BOM
The 1 pA typical input bias current and 300 µV input offset voltage are the specs that matter for high-impedance sensor front-ends — think piezo film, pyroelectric detectors, or high-value resistive bridges where bias current drift would swamp the signal. The 50 mA per-channel output current is enough to drive the analog input of a typical automotive ADC or a moderate-length shielded cable, but not a relay coil or solenoid. Supply current of 2.4 mA per amplifier keeps the thermal budget manageable in a densely populated ECU board.
Lifecycle and sourcing
The TLC2272AQPWRQ1 carries an Active product status with no NRND or EOL flags. ROHS3 compliant. For a BOM freeze on an automotive program, this part is a safe line item — no last-time-buy clock ticking. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time. The AEC-Q100 qualification is documented, so no additional PPAP paperwork should be needed for Tier-1 submissions.
