OPA2890IDGST

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2890IDGST is a dual low-power wideband voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 120 MHz and a slew rate of 400 V/us. The device operates on a supply voltage range of 3 V to 12 V with a typical quiescent current of 1.1 mA per channel. Key electrical specifications include an input voltage noise density of 8.1 nV/sqrt Hz, an output current capability of 40 mA per channel, and a voltage gain of 62 dB. It is housed in a 10-pin MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDGST corresponds to the MSOP-10 package and tape-and-reel or cut-tape availability as listed by distributors. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference ordering part numbers with authorized suppliers to avoid counterfeit components.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between moderate bandwidth and low power consumption is required. The 120 MHz gain-bandwidth product supports applications needing faster response than standard op-amps but less speed than ultra-high-speed variants. Consider the 40 mA output drive capability for driving moderate loads. Evaluate the 8.1 nV/sqrt Hz noise density against system noise budgets. Compare pinout compatibility if replacing legacy devices in existing designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA2890 series of dual wideband operational amplifiers from Texas Instruments. It is designed for applications requiring good speed-performance trade-offs. The family typically includes variants with different packaging options such as SOIC or QFN, though the IDGST specifically denotes the MSOP-10 form factor. It serves as a solution for space-constrained designs needing dual-channel functionality.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible alternatives within the TI portfolio that offer similar bandwidth and power specs. Verify if upgraded packages like the OPA2890IDGSR (tape and reel) meet logistical needs. Ensure any substitute maintains the same MSOP-10 footprint if board space is fixed.
