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.
0°C to 70°C — commercial temperature grade, indoor use only
The operating temperature range is 0°C to 70°C, which places this part in the commercial-grade bucket. 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.
Sourcing and availability — active, quoted to order
The 14-SOIC package ships in Tape & Reel (TR) or Cut Tape (CT) options, matching standard pick-and-place assembly lines.
