What are the key features of TL032AIDG4?
- Dual op-amp with 70 dB minimum / 87 dB typical CMRR, providing strong common-mode noise rejection for precision analog front-ends
- 200 pA maximum input bias current at 25°C enables accurate signal conditioning from high-impedance sources without significant loading error
- Internally compensated voltage-feedback architecture in a compact SOIC-8 package, simplifying PCB design for dual-channel amplifier circuits
What is TL032AIDG4 used for?
The TL032AIDG4 is suited for dual-channel signal conditioning, active filter stages, and instrumentation amplifier building blocks in industrial sensors, medical monitoring equipment, and test-and-measurement instruments. Its 200 pA bias current and 87 dB typical CMRR make it effective in bridge amplifiers and precision voltage followers where source impedances exceed 1 MΩ and common-mode interference must be rejected.

Frequently Asked Questions
How does TL032AIDG4's 200 pA bias current compare to standard general-purpose op-amps in high-impedance bridge sensor circuits?
Standard bipolar op-amps such as the LM358 can have input bias currents of 20 nA to 100 nA, which across a 1 MΩ source resistance generate 20 mV to 100 mV of offset error. The TL032AIDG4's 200 pA maximum bias current reduces this error to only 0.2 mV across the same 1 MΩ source, improving DC accuracy by 2 to 3 orders of magnitude and eliminating the need for bias-current compensation resistors in most bridge amplifier designs.
For a dual-channel active low-pass filter in an industrial sensor module, what CMRR performance does TL032AIDG4 provide?
The TL032AIDG4 provides a minimum CMRR of 70 dB and a typical CMRR of 87 dB, meaning a 1 V common-mode signal at the input appears as no more than 316 µV at the output in the worst case (70 dB), and typically only 45 µV (87 dB). In a 4–20 mA industrial sensor module where supply and ground bounce can reach hundreds of millivolts, this 70 dB minimum CMRR suppresses interference to below the noise floor of most 12-bit ADCs.
When is TL032AIDG4 preferred over a single-supply rail-to-rail op-amp in a split ±5 V instrumentation design?
In split-supply ±5 V designs, the output swing requirement is typically from –4 V to +4 V, which a standard op-amp like TL032AIDG4 can achieve without the overhead of a rail-to-rail output stage. The absence of a rail-to-rail output stage in TL032AIDG4 avoids the crossover distortion artifacts that some rail-to-rail output stages introduce near the supply rails, resulting in lower THD at signal amplitudes up to ±3.5 V — an advantage in precision DC measurement circuits and low-distortion audio signal paths.
What are the key electrical differences between TL032AIDG4 and TL072 that guide part selection?
The TL032AIDG4 and TL072 are both dual JFET-input op-amps in SOIC-8 packages, but TL032AIDG4 specifies a 200 pA maximum input bias current at 25°C and 4.6 mV maximum input offset voltage, while TL072 typically specifies 200 pA bias current and 3 mV to 5 mV offset. The TL032AIDG4 offers a 70 dB minimum CMRR versus TL072's 80 dB typical, so for designs requiring guaranteed CMRR at temperature extremes, reviewing both datasheets against the specific operating conditions — supply voltage, temperature range, and frequency — is recommended.
