What are the key features of TL034INE4?

  • Quad JFET-input op-amp with 0.0009 µA maximum average bias current per amplifier, enabling high-impedance signal conditioning across 4 channels in a single DIP-14 package
  • 75 dB minimum common-mode rejection ratio with ±15 V supply supports differential signal amplification in noisy industrial and audio environments
  • 14-pin PDIP (through-hole) package in tube packaging simplifies prototyping and socketed board assembly for industrial instrumentation and lab equipment

What is TL034INE4 used for?

The TL034INE4 is used in multi-channel analog front ends for industrial sensors, audio mixing boards, and active filter banks where four low-bias-current amplifiers in a single 14-pin DIP simplify board layout. Its JFET input stage makes it appropriate for buffering high-impedance sources such as piezoelectric sensors, capacitive microphones, and photodiode arrays. The device also suits summing amplifier networks and integrator circuits in signal-processing boards where through-hole assembly is preferred.

Frequently Asked Questions

How does the TL034INE4 quad configuration reduce component count in a 4-channel analog signal conditioning board?

Using the TL034INE4, all 4 amplifier channels share a single 14-pin PDIP footprint, reducing the PCB area and component count compared to four discrete single-channel op-amp packages each requiring their own decoupling capacitors and separate footprints. In a 4-channel strain-gauge bridge amplifier running from ±15 V rails, this saves roughly 3 package placements and 8 bypass capacitors from the BOM, and routing 4 channels through 1 package instead of 4 reduces trace interconnect length by 30% to 50%.

For high-impedance capacitive sensor interfaces, how does the 0.0009 µA bias current of the TL034INE4 compare to a standard bipolar quad op-amp?

The TL034INE4 JFET input stage limits the average bias current to 0.0009 µA, whereas a typical bipolar quad op-amp such as the LM324 draws up to 45 nA to 250 nA input bias current. When buffering a 100 MΩ source like a capacitive humidity sensor, the TL034INE4 error voltage is under 90 µV, while a 250 nA bipolar device would introduce up to 25 mV of offset — over 270 times larger — which would dominate the measurement error in a 16-bit system.

When designing a 4-channel active bandpass filter for audio frequencies, what CMRR performance does the TL034INE4 provide against 50 Hz hum?

The TL034INE4 provides a minimum CMRR of 75 dB and a typical CMRR of 87 dB at DC, meaning 50 Hz mains hum present equally on both inputs is attenuated by at least 5,600 times before reaching the differential output. In practice at 50 Hz with a ±15 V supply, the 87 dB typical rejection reduces a 1 V common-mode hum signal to under 45 µV at the output, keeping it well below the noise floor of most 16-bit audio ADCs with a 2 Vrms input range.
