What are the key features of TL288CPE4?
- Dual FET-input op-amp with 0.0002 µA bias current at 25°C, enabling ultra-low-leakage signal conditioning in high-impedance sensor interfaces
- 3 MHz gain-bandwidth product with rail-to-rail output swing for maximum dynamic range in low-voltage analog circuits
- 500 µV maximum input offset voltage and 80 dB minimum CMRR supporting precision measurement and instrumentation applications in 8-pin PDIP
What is TL288CPE4 used for?
TL288CPE4 is used in precision instrumentation, sensor signal conditioning, and active filter circuits where FET-input ultra-low bias current (0.0002 µA) and 3 MHz bandwidth are essential for accurate amplification of signals from high-impedance sources such as photodetectors, pH electrodes, and piezoelectric sensors. Its rail-to-rail output and 80 dB CMRR also make it suitable for audio preamplifiers, sample-and-hold circuits, and medical measurement equipment in through-hole 8-pin PDIP board designs.

Frequently Asked Questions
What input bias current and bandwidth specs does the TL288CPE4 provide for sensor interface designs?
The TL288CPE4 offers an extremely low bias current of 0.0002 µA at 25°C with a 3 MHz gain-bandwidth product, making it ideal for high-impedance sensor interfaces such as photodetectors and pH probes where ultra-low input leakage and sufficient bandwidth are both required in a dual op-amp configuration.
How does the TL288CPE4 compare to bipolar input op-amps for high-impedance signal amplification?
Compared to bipolar input op-amps, the TL288CPE4 FET-input design delivers 0.0002 µA bias current versus typical bipolar levels of 10 to 100 nA, reducing offset errors across high-impedance sources. Its 500 µV maximum input offset and 80 dB minimum CMRR maintain measurement accuracy while the 3 MHz bandwidth supports audio and instrumentation signal frequencies.
Which precision measurement applications benefit from the TL288CPE4 in an 8-pin PDIP package?
The TL288CPE4 in an 8-pin PDIP package suits bench instrumentation, laboratory signal conditioners, and educational electronics prototypes where through-hole assembly, dual FET-input channels, 3 MHz bandwidth, and rail-to-rail output swing enable precise analog measurements without the cost or handling difficulty of surface-mount alternatives.
What CMRR performance does the TL288CPE4 deliver and why does it matter in differential measurement circuits?
The TL288CPE4 achieves a minimum CMRR of 80 dB and a typical CMRR of 93 dB, suppressing common-mode noise by at least 10,000:1. This high rejection is critical in differential measurement circuits such as bridge amplifiers, instrumentation front ends, and medical ECG inputs where line-frequency interference must be rejected while small 1 mV to 10 mV differential signals are accurately amplified.
