Overview
The TL072HIDDFR is a dual operational amplifier from Texas Instruments featuring JFET inputs and rail-to-rail output capability. It operates within a supply voltage range of 4.5 V to 40 V, with a gain-bandwidth product of 5.25 MHz and a slew rate of 20 V/us. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 120 pA, and input voltage noise density of 37 nV/sqrt Hz. The device supports a common-mode rejection ratio of 80 dB and delivers 10 mA per channel output current. It functions reliably across temperatures from -40 C to +125 C in an SOT-23-8 package.
Feature Summary
- Dual-channel architecture with JFET input stage for low bias current
- Rail-to-rail output swing capability for extended dynamic range
- High slew rate and gain-bandwidth product for signal integrity
Applications
- Precision analog signal conditioning circuits
- Audio pre-amplification stages requiring low noise
- Industrial sensor interface applications
Procurement Notes
Verify the specific suffix IDDFR indicates the SOT-23-8 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation as distributor listings may vary. Ensure the component matches the required operating temperature range of -40 C to +125 C for your specific application environment before finalizing procurement.
Selection Notes
Select this component when rail-to-rail output is necessary alongside JFET input characteristics. Compare against standard TL072 variants if higher bandwidth or lower offset voltage is required. Consider the SOT-23-8 footprint constraints versus traditional DIP packages for PCB layout optimization.
Part Context
This part belongs to the TL072H series, representing an enhanced version of the classic TL072 family. It updates the legacy design with modern packaging and improved electrical specifications such as increased bandwidth and rail-to-rail output capabilities while maintaining the low-noise JFET input structure.
Replacement Considerations
Direct substitutes include other dual JFET op-amps with rail-to-rail outputs like the OPA2134 or LM833, provided pin compatibility and electrical specs align. Verify package dimensions for SOT-23-8 alternatives.
