Product details

Dual rail-to-rail op-amp for industrial and automotive signal chains

The Texas Instruments OPA2991IPWR is a dual-channel, general-purpose operational amplifier with rail-to-rail output, 4.5 MHz gain-bandwidth product, and a 21 V/µs slew rate. It operates from a 2.7 V to 40 V supply span and is rated over the -40°C to 125°C temperature range.

Lifecycle and sourcing posture

The OPA2991IPWR carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. For dual-sourcing resilience, the TLV9362IDDFR is a close functional peer — same dual-channel count, 10.6 MHz GBW, 25 V/µs slew, and 2.7-40 V supply — but verify pin-compatibility against your layout before substituting. The part is sourced to order through independent distribution.

Frequently asked questions

What is the equivalent of OPA2991IPWR?

A close functional equivalent is the TLV9362IDDFR, also a dual-channel general-purpose op-amp with rail-to-rail output, 10.6 MHz GBW, 25 V/µs slew, and 2.7-40 V supply. Verify pin-compatibility before substituting.

What is the difference between OPA2991 and OPA2990?

The OPA2991 offers a 4.5 MHz gain-bandwidth product and 21 V/µs slew rate, while the OPA2990 is a lower-speed variant typically specified at 1 MHz GBW and 0.5 V/µs slew. The OPA2991 is the higher-bandwidth choice for faster signal chains.
