Quad general-purpose op-amp with CMOS inputs — 2.2 MHz, 14-SOIC
The Texas Instruments TLC274BCDR is a quad-channel general-purpose op-amp in a 14-SOIC package, built on a CMOS process that delivers 0.6 pA input bias current — low enough to interface directly with high-impedance sensors without a separate buffer. Each of the four amplifiers provides a 2.2 MHz gain-bandwidth product and a 3.6V/µs slew rate, adequate for audio-band signal conditioning, active filters below 200 kHz, and multi-channel data acquisition front-ends. The supply range spans 3 V to 16 V, allowing single-rail operation at 5 V or split supplies up to ±8 V. Output current is rated 30 mA per channel, sufficient to drive a 2 kΩ load to within a few hundred millivolts of the rails.
It is suited for benchtop instruments, office equipment, appliance control boards, and indoor industrial panels where ambient temperature stays within that window. If the design must survive −40°C cold starts or 85°C+ enclosures, a different grade — such as the TLV9362IDDFR rated −40°C to 125°C — would be the correct choice.
Supply voltage range: 3 V to 16 V — single 5 V operation confirmed
The TLC274BCDR operates from a minimum supply of 3 V up to a maximum of 16 V. This covers the common 5 V single-supply rail (the part runs fine on a single 5 V supply) as well as ±5 V split supplies. At 5 V the input common-mode range extends from the negative rail to about 1.5 V below the positive rail — not rail-to-rail on the input side. The output can swing within about 100 mV of the rails under light load, but at 30 mA output the swing is reduced. For rail-to-rail input/output, a newer CMOS part like the OPA4374 would be needed.
