TL972IDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The TL972IDRG4 is a dual operational amplifier manufactured by Texas Instruments, featuring rail-to-rail output capability and very-low-noise performance. It operates within a supply voltage range of 2.7 V to 16 V and supports an extended industrial temperature range from -40°C to +125°C. The device integrates two independent amplifiers in an 8-pin SOIC (D) package with a tape-and-reel configuration. Key electrical characteristics include a gain-bandwidth product of 3 MHz, a slew rate of 2.4 V/µs, and an input offset voltage of 2 mV.

• Audio preamplifier circuits
• Battery-powered instrumentation systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm lead-free compliance and RoHS status. Ensure the package designation matches the required PCB footprint. Confirm that the tape-and-reel quantity aligns with assembly line requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both low noise and rail-to-rail output are critical requirements. Compare the 3 MHz bandwidth and 2.4 V/µs slew rate against application signal frequencies. Evaluate the 2 mV input offset voltage tolerance relative to system accuracy needs. Consider the 8-pin SOIC package dimensions for board space constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The TL972IDRG4 belongs to the TL97x family of operational amplifiers designed for high-performance analog signal processing. This series emphasizes low noise and wide output swing capabilities. The 'I' grade indicates industrial temperature rating, while 'DR' specifies the SOIC package and reel packaging. It serves as a dual-channel variant within the broader TL97x portfolio.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers include TL972IDRGR and TL972IPW. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any functional differences between the standard TL972 and automotive-grade variants like TL972QPWRQ1 if reliability standards differ.
