OPA4820IPWT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4820IPWT is a quad low-noise voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 250 MHz and a slew rate of 240 V/us. The device delivers a voltage gain of 66 dB with an input voltage noise density of 2.5 nV/sqrt Hz. Each channel provides an output current of 85 mA, while the input bias current is 26 uA and the input offset voltage is 250 uV. It operates on a supply voltage ranging from 4 V to 12.6 V, consuming 5.7 mA per channel. The unit is housed in a TSSOP-14 package and functions within a temperature range of -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IPWT corresponds to the TSSOP-14 surface-mount package configuration. Confirm that the component meets RoHS compliance requirements as indicated in official specifications. Ensure compatibility with standard SMD/SMT assembly processes. Check humidity sensitivity levels prior to storage and handling to prevent moisture-related damage during reflow soldering.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels of low-noise amplification are required alongside high bandwidth. The quad configuration reduces board space compared to single-channel alternatives. Consider the 85 mA output current for driving moderate loads without external buffers. Evaluate the 2.5 nV/sqrt Hz noise density against system sensitivity requirements to ensure adequate signal-to-noise ratio.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA4820 series of high-speed operational amplifiers. It shares core electrical characteristics with variants such as OPA4820ID but differs in packaging. The IPWT designation specifically identifies the TSSOP-14 form factor, distinguishing it from SOIC or other package types within the same functional family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes include OPA4820ID for SOIC-14 applications where package changes are acceptable. Verify electrical parameters match exactly if substituting with other quad op-amps.
