Quad op-amp with low power and rail-to-rail swing
The TLC2264CD is a quad-channel general-purpose operational amplifier from Texas Instruments' LinCMOS™ series, packaged in a 14-SOIC (0.154", 3.90 mm width) surface-mount package. It draws 850 µA total across all four amplifiers — roughly 212 µA per channel — making it a fit for multi-channel signal conditioning where the power budget is tight. The 730 kHz gain-bandwidth product and 0.55 V/µs slew rate place it in the general-purpose band: adequate for audio-frequency filtering, sensor buffering, and control-loop conditioning, but not for video-rate or fast-switching paths.
Input characteristics and output drive
Input bias current is 1 pA typical — the CMOS input stage keeps the error negligible for high-impedance sources like photodiode or pH probe front-ends. Input offset voltage is 300 µV, which sets the DC accuracy floor for the signal chain; a gain-of-100 stage amplifies this to 30 mV at the output before any sensor signal. Rail-to-rail output stage delivers up to 50 mA per channel, enough to drive a 100-ohm load to within a few hundred millivolts of the supply rails. Supply range spans 4.4 V to 16 V, so it runs from a single 5 V or 12 V rail without needing a split supply — check the common-mode input range against the rail at the lower end.
Package, temperature grade, and compliance
Supplier device package is 14-SOIC, a standard footprint shared with many quad op-amps — layout reuse across alternate parts is straightforward. Rated for 0°C to 70°C commercial temperature range, so it is suited for indoor equipment, bench instruments, and controlled-environment control panels, not for under-hood or outdoor exposed enclosures.
