Frequently Asked Questions

What is the input bias current of the TL051CD?

The TL051CD features an extremely low maximum input bias current (IIB) of 0.0002µA (200pA) at 25°C, and a maximum input offset current (IIO) of 0.0001µA (100pA). These ultra-low values make it ideal for high-impedance signal sources such as photodiodes and pH electrodes where large bias currents would introduce significant measurement errors.

What applications is the TL051CD best suited for?

The TL051CD is best suited for precision instrumentation, active filters, signal conditioning, transimpedance amplifiers, data acquisition systems, and medical measurement equipment. Its JFET input provides high input impedance and low noise, while its 93dB typical CMRR and internal frequency compensation make it reliable for differential measurement and stable closed-loop designs in industrial and audio applications.

What package does the TL051CD come in and who manufactures it?

The TL051CD is manufactured by Texas Instruments and comes in an SOIC (Small Outline Integrated Circuit) surface-mount package, making it compatible with standard SMD assembly processes. The 'D' suffix in the part number designates the SOIC package. It is RoHS compliant (Pbfree Code: Yes) and widely available from authorized distributors with pricing starting around $0.59 per unit.

What is the common-mode rejection ratio (CMRR) of the TL051CD?

The TL051CD offers a minimum CMRR of 75dB and a typical CMRR of 93dB. This high rejection ratio ensures that common-mode noise and interference present on both input lines is effectively suppressed, making the amplifier well-suited for differential measurement applications in noisy industrial environments, motor drives, and precision bridge sensor readout circuits.
