TLV272IP

Instrumentation, Op Amps, Buffer Amps Overview

The TLV272IP is a dual-channel operational amplifier from Texas Instruments, housed in an 8-pin PDIP package. It operates on a supply voltage range of 2.7 V to 16 V (±1.35 V to ±8 V). Key electrical parameters include a gain-bandwidth product of 3 MHz and a slew rate of 2.4 V/µs at 5 V. The device draws 550 µA per channel. Input characteristics feature a bias current of 1 pA and offset voltage of 5 mV. Output swing is rail-to-rail. Operating temperature ranges are 0°C to 70°C for commercial grade and -40°C to 125°C for industrial grade.

• CMOS inputs enable high-impedance sensor interfaces with ultra-low input bias current
• Wide bandwidth and high slew rate support fast signal processing
• Compatible with single or split power supplies down to 2.7 V

Instrumentation, Op Amps, Buffer Amps Applications

• E-Bike systems
• Power banks
• Smoke detectors
• Solar inverters
• Battery-powered instruments

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix 'IP' corresponds to the PDIP package and Industrial temperature range (-40°C to 125°C) as specified in the datasheet. Confirm that the commercial grade variant uses the 'IC' suffix if a narrower temperature range is acceptable. Ensure the ordering information matches the latest revision of the datasheet to avoid discrepancies in package dimensions or electrical specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output is required alongside low power consumption. It serves as a direct upgrade for the TLC72x family where wider bandwidth is needed. Consider the 550 µA/ch quiescent current for battery life calculations. Verify capacitive load handling requirements, as series isolation resistors may be necessary for loads exceeding 10 pF to maintain stability.

Instrumentation, Op Amps, Buffer Amps Part Context

The TLV272IP belongs to the TLV27x family of low-power, wide-bandwidth operational amplifiers. This family includes single (TLV271), dual (TLV272), and quad (TLV274) variants. The devices are designed for portable and battery-powered applications due to their compatibility with Li-Ion systems and microcontrollers like the MSP430. They offer improved performance over the legacy TLC27x series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The TLV272ID is a surface-mount alternative in the SOIC-8 package with identical electrical characteristics. For automotive applications requiring AEC-Q100 qualification, the TLV272QDRQ1 is available. The TLC722 is a legacy replacement but lacks rail-to-rail output and has lower bandwidth.
