TLV272IDGKG4

Instrumentation, Op Amps, Buffer Amps Overview

The TLV272IDGKG4 is a dual-channel operational amplifier from the Texas Instruments TLV27x family, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 2.7 V to 16 V or split supplies of ±1.35 V to ±8 V. The device features rail-to-rail output capability and consumes 550 µA per channel. Key electrical specifications include a gain-bandwidth product of 3 MHz, a slew rate of 2.4 V/µs, an input offset voltage of 5 mV, and an input bias current of 1 pA. It supports an industrial temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output stage enables full dynamic range operation in low-voltage systems.
• CMOS inputs provide ultra-low input bias current for high-impedance sensor interfaces.
• Wide bandwidth and high slew rate support fast signal processing with minimal power consumption.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instruments
• Low-power motor controls
• Building automation systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific DGKG4 suffix indicates the VSSOP-8 package variant. Confirm the 'I' suffix corresponds to the extended industrial temperature range (-40°C to +125°C). Ensure the component matches the original datasheet revision E specifications for DC and AC performance parameters before integration into production designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output swing is required alongside low quiescent current consumption. It serves as a direct upgrade path for legacy TLC72x family applications requiring improved bandwidth and lower noise. Suitable for designs operating from single 2.7 V sources or standard 5 V logic levels.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLV27x family of low-power, wide-bandwidth operational amplifiers. The family includes single (TLV271), dual (TLV272), and quad (TLV274) variants. The TLV272 specifically integrates two independent amplifiers in compact packaging options including SOIC, PDIP, and VSSOP, designed for portable and battery-operated electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The TLV272CDR is a commercial grade alternative in an SOIC-8 package. The TLV272DR2G is listed as an available substitute from onsemi. Verify pin compatibility and thermal characteristics when substituting packages.
