Active production, low-power quad op-amp
The Texas Instruments TLC25L4CDR is a CMOS quad operational amplifier from the LinCMOS™ series, packaged in a 14-SOIC. It draws 2.7 mA total supply current across all four channels, making it a fit for multi-channel battery-powered or thermally constrained analog front-ends. The open-drain output stage means it is not rail-to-rail — plan for external pull-up resistors if you need a logic-level output swing.
Package and mounting
It is designed for DC-precise or low-frequency signal conditioning — thermocouple amplifiers, strain-gauge bridges, or battery-voltage monitoring — where speed would trade off against noise or power. The 0.6 pA input bias current preserves accuracy when the source impedance is high, like a photodiode or pH probe.
Supply range from 1.4 V to 16 V
The supply span covers 1.4 V minimum to 16 V maximum, so a single Li-ion cell (down to its end-of-discharge voltage) or a standard 12 V industrial rail both work without a secondary regulator.
