TL081CDR Texas Instruments Operational Amplifiers (SOIC-8) In Stock
The TL081CDR is a high-performance JFET-input general-purpose operational amplifier from Texas Instruments, offered in a compact SOIC-8 surface-mount package. It features a JFET input stage for very low input bias current (typically 30 pA), wide gain-bandwidth product of 3 MHz, and a high slew rate of 13 V/µs. With a supply voltage range of ±5 V to ±18 V and low input offset voltage, it is widely used in precision analog signal conditioning, active filters, sample-and-hold circuits, and audio applications. The 'C' grade specifies commercial temperature range (0°C to +70°C), and the 'D' suffix denotes the SOIC-8 package.

Alternate & Equivalent Parts
Compatible alternatives and drop-in replacements for TL081CDR:
Same JFET-input single op-amp family, lower noise (18 nV/√Hz vs 18 nV/√Hz), same SOIC-8 package — preferred for audio and noise-sensitive designs
Low-power variant of the TL08x family, ~200 µA supply current vs 1.4 mA, same SOIC-8 pinout — use for battery-powered applications
Classic BJT-input op-amp in same SOIC-8 package; lower slew rate and higher input bias current, but widely available as legacy replacement
High-performance BJT op-amp with lower noise (3.5 nV/√Hz), same SOIC-8 package, preferred for professional audio preamplifier stages
Frequently Asked Questions
What is the TL081CDR?
The TL081CDR is a JFET-input general-purpose operational amplifier from Texas Instruments in an SOIC-8 surface-mount package. It offers very low input bias current (30 pA), a 3 MHz gain-bandwidth product, and a 13 V/µs slew rate, making it suitable for precision analog and audio applications.
What does the 'C' suffix mean in TL081CDR?
The 'C' in TL081CDR indicates the commercial temperature grade, meaning the device is specified for operation from 0°C to +70°C ambient temperature.
What package does the TL081CDR use?
The TL081CDR uses the SOIC-8 (Small Outline IC, 8-pin) surface-mount package, designated by the 'D' suffix in the part number. It has a 1.27 mm pin pitch and is compatible with standard PCB reflow soldering.
What is the supply voltage range for TL081CDR?
The TL081CDR operates from a dual supply of ±5 V to ±18 V (total supply 10 V to 36 V). It does not support single-supply operation directly because the input common-mode range does not extend to the negative rail.
What are common applications for the TL081CDR?
Common applications include active filters, precision amplifiers, sample-and-hold circuits, audio signal conditioning, transimpedance amplifiers, integrators, and voltage followers where low input bias current and moderate bandwidth are required.
How does TL081CDR compare to TL071 and TL061?
The TL081, TL071, and TL061 are all JFET-input op-amps from Texas Instruments. The TL081 has the highest slew rate (13 V/µs) and highest supply current (~1.4 mA). The TL071 offers lower noise, while the TL061 prioritizes low power consumption (~200 µA). Choose TL081 for speed, TL071 for noise-sensitive designs, and TL061 for battery-powered applications.
Is the TL081CDR RoHS compliant?
Yes, the TL081CDR in SOIC-8 package is manufactured with lead-free, RoHS-compliant materials. Always verify the specific date code and packaging marking on the reel label or datasheet for the latest compliance status.
What is the input bias current of TL081CDR?
The TL081CDR has a typical input bias current of 30 pA at 25°C due to its JFET input stage. This is significantly lower than BJT-input op-amps, making it ideal for high-impedance sensor interfaces and charge amplifier circuits.
