TL972IPG4

Instrumentation, Op Amps, Buffer Amps Overview

The TL972IPG4 is a dual-channel operational amplifier manufactured by Texas Instruments, featuring rail-to-rail output and very low noise characteristics. It operates within a supply voltage range of 1.35 V to 6 V for dual supplies or 2.7 V to 12 V for single supplies. Key electrical parameters include an input offset voltage of 4 mV, input bias current of 750 nA, and a quiescent current of 2 mA per channel. The device delivers an output current of 80 mA per channel with a common-mode rejection ratio of 85 dB. It is housed in an 8-TSSOP package and supports operating temperatures from -40°C to +125°C.

• Very-low-noise design ensures high signal integrity for sensitive circuits.
• Wide single-supply operation allows flexibility in power system design.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered portable instrumentation
• Low-voltage signal conditioning
• Audio preamplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IPG4 against the official Texas Instruments datasheet to confirm the TSSOP-8 package and industrial temperature grade. Confirm end-of-life status as distributor listings may indicate obsolescence for this specific revision. Ensure compatibility with your PCB footprint for the 8-pin thin-shrink small-outline package before ordering.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TL972IPG4 when rail-to-rail output swing is required alongside low noise performance in single-supply systems. Compare input offset voltage and bias current requirements against other family members like the TL971 (single) or TL974 (quad). Verify that the 80 mA output current meets load drive needs and that the 12 MHz gain-bandwidth product suits the application frequency.

Instrumentation, Op Amps, Buffer Amps Part Context

The TL972IPG4 belongs to the TL97x family of operational amplifiers designed for low-voltage, low-noise applications. This family emphasizes efficiency and signal fidelity in portable devices. The 'IPG4' designation indicates a lead-free, green compound (RoHS compliant) version in the TSSOP-8 package, aligning with environmental standards while maintaining the core electrical specifications of the standard TL972 series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for TL972IDRGR or TL972IDRG4 for tape-and-reel packaging alternatives. Single-channel equivalents include TL971 variants, while quad-channel needs may be met by TL974 counterparts. Verify pinout compatibility and thermal performance when substituting.
