TL064 / TL074 / TL084 Quad JFET Op-Amp IC — DIP-14, ±2.25–18V, 3MHz GBW (5-Pack)

TL064 / TL074 / TL084 Quad JFET Op-Amp IC — DIP-14, ±2.25–18V (5-Pack)

The TL06x/TL07x/TL08x series are quad JFET-input operational amplifiers in DIP-14 package — four independent op-amps per IC. The JFET input stage provides ultra-low input bias current (~65pA), making them ideal for high-impedance sensor interfaces, sample-and-hold circuits, and audio applications where bipolar op-amps (like the LM741) would cause excessive loading. Pack of 5 (select variant).

Variant Comparison

• TL064CN (low-power): ~200μA per amp, 1MHz GBW, 3.5V/μs slew rate — for battery-powered audio and sensor circuits
• TL074CN (standard): ~1.4mA per amp, 3MHz GBW, 13V/μs slew rate — most popular, for audio filters and signal processing
• TL084CN (wide-bandwidth): ~1.4mA per amp, 3MHz GBW, 13V/μs slew rate — equivalent to TL074, different manufacturer designation

Common Specifications

• Package: DIP-14 (through-hole, 2.54mm pitch)
• Op-Amps: 4 independent channels
• Input Type: JFET (input bias current ~65pA)
• Supply Voltage: ±2.25V to ±18V (dual supply)
• Input Offset Voltage: 3mV typical
• Output Short-Circuit Protected: Yes
• Operating Temperature: 0°C to +70°C (commercial)
• Pack Quantity: 5 ICs (20 op-amp channels total)

TL074 vs LM324 vs UA741

• TL074 JFET (this IC): 65pA bias, 3MHz GBW, 13V/μs — for audio and high-impedance applications
• LM324: Single supply, 1MHz GBW, 0.5V/μs, bipolar — for single-supply sensor circuits
• UA741: Single amp, 1MHz GBW, 0.5V/μs, bipolar — classic teaching op-amp only

Typical Applications

• Active audio filter (Sallen-Key, MFB topology)
• Audio preamplifier and mixer
• Sample-and-hold circuit
• High-impedance sensor interface (pH, piezo)
• Waveform generator (Wien bridge oscillator)
