OPA4141AIPWR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4141AIPWR is a quad-channel, single-supply, low-noise JFET precision operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 10 MHz and a slew rate of 20 V/µs. The device operates within a supply voltage range of 4.5 V to 36 V and supports an output current of 36 mA per channel. Key electrical specifications include an input offset voltage of 3.5 mV, input bias current of 2 pA, power supply rejection ratio of 137 dB, and common-mode rejection ratio of 120 dB. It functions reliably across a temperature range of -40°C to 125°C in a 14-pin TSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing. Confirm the 'A' grade designation matches required offset voltage tolerances. Ensure the 14-TSSOP footprint aligns with PCB design constraints. Cross-reference the manufacturer part number against official TI databases to avoid counterfeit components. Check for RoHS compliance status if environmental regulations apply to the end product.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad-channel configuration is necessary to reduce board space compared to single-channel alternatives. The JFET input stage offers superior bias current characteristics compared to bipolar inputs, making it ideal for high-impedance sources. Consider the 10 MHz bandwidth as sufficient for most audio and general-purpose precision applications. Evaluate the 36 V maximum supply voltage against system power rails to ensure adequate headroom without exceeding limits.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPAx141 family of precision amplifiers from Texas Instruments. It shares architectural similarities with the OPA141 (single) and OPA2141 (dual) variants but integrates four channels into one package. The family is characterized by JFET inputs, low noise, and high speed, targeting applications where multiple precision amplification stages are required in a compact form factor.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same package include OPA4141AIDR. For different packaging requirements, consider OPA4141AIPW. Single-channel equivalents like OPA141AIDR can be used if pin count flexibility exists.
