TLV2444AIPWR

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2444AIPWR is a quad operational amplifier from Texas Instruments utilizing Advanced LinCMOS technology. It features rail-to-rail output and wide-input-voltage capability, operating on a single supply of 2.7 V to 10 V or split supplies. The device offers low input offset voltage (950 µV max at 25°C), low bias current (60 pA typical), and high gain bandwidth product (1.8 MHz typical). It provides 750 µA per channel supply current and operates within an extended temperature range of -40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output performance for increased dynamic range in single- or split-supply applications
• Extended common-mode input voltage range without phase inversion when driven to supply rails
• Low noise characteristics with 16 nV/√Hz typical input voltage noise density
• High input impedance suitable for small-signal conditioning of high-impedance sources

Instrumentation, Op Amps, Buffer Amps Applications

• Small-signal conditioning for high-impedance sources such as piezoelectric transducers
• Hand-held monitoring and remote-sensing applications due to micropower dissipation
• Interfacing with analog-to-digital converters (ADCs) using single- or split-supplies
• Telecommunications applications driving 600-Ω loads

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package and 'A' indicates the precision grade with 950 µV max input offset voltage. Confirm the operating temperature range matches the 'I' suffix specification (-40°C to 125°C) required for your design environment. Ensure supply voltage constraints align with the 2.7 V to 10 V absolute maximum ratings.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output swing is critical but full rail-to-rail input is not strictly necessary, offering a cost-effective alternative to premium RRIO amplifiers. Consider the TLV2444AIPWR for designs requiring low power consumption alongside moderate speed and precision. Evaluate the 1.8 MHz gain-bandwidth product against signal frequency requirements to ensure adequate phase margin and stability under expected load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLV244x family of low-voltage operational amplifiers. It shares architectural similarities with the dual-channel TLV2442A but contains four independent amplifiers. The 'A' variant distinguishes itself from standard TLV2444 models by offering tighter input offset voltage specifications. It is part of a broader portfolio including micro-power TLV2422 and low-power TLV243x versions.
