Quad CMOS op-amp for micropower signal conditioning
The Texas Instruments TLC27L4CDR is a quad CMOS op-amp from the LinCMOS series, packing four independent amplifiers into a 14-SOIC package. Supply current is 57 µA per channel.
What the key ratings mean for your BOM
The 0.7 pA input bias current means you can use megohm-range feedback resistors without adding offset errors — a real advantage for precision DC circuits. The 1.1 mV input offset voltage is typical for a general-purpose CMOS stage; if your application demands sub-millivolt accuracy, plan for a trim or select a zero-drift amplifier. Output current is rated at 30 mA per channel, enough to drive a reference input or a small relay coil, but not a power load. The 0°C to 70°C temperature range limits this part to commercial indoor environments — not for automotive or industrial enclosures without climate control.
Lifecycle and sourcing posture
The TLC27L4CDR carries an Active product status with ROHS3 compliance. No NRND or EOL flags appear in the record — it remains a current-production part suitable for new designs. Sourcing is through independent distribution; availability and pricing are confirmed at quote time. The 14-SOIC footprint is common across TI's quad op-amp family.
