Product details

The 5 V to 12 V supply span gives flexibility: run it on a single 5 V rail for a 2 Vpp output swing, or go to ±5 V for a wider dynamic range. No compensation pin is needed; current-feedback amps are inherently stable at the gain set by the feedback resistor value, which the datasheet recommends for a given bandwidth target.

For a high-speed op-amp in a small SOT-23-6, that means the design is not locked to a surplus channel; standard distribution handles it.

Package and mounting — SOT-23-6 footprint

Surface-mount in a SOT-23-6 package (supplier device package same as the case code).

Where it is used

Typical applications include high-speed ADC driver stages, video distribution amplifiers, cable drivers, pulse generators, and IF amplifier chains in communications receivers. The industrial temperature range suits outdoor telecom cabinets, factory automation sensor interfaces, and test equipment that sees ambient swings.

Frequently asked questions

What is the OPA691IDBVT bandwidth and slew rate?

The OPA691IDBVT has a -3 dB bandwidth of 280 MHz and a slew rate of 2100 V/µs.

What is the OPA691IDBVT pinout and package?

The OPA691IDBVT comes in a SOT-23-6 surface-mount package (supplier device package SOT-23-6). The pinout is standard for a single current-feedback op-amp in that footprint.

Does OPA691IDBVT require external compensation?

No. As a current-feedback amplifier, the OPA691IDBVT is inherently stable at the gain set by the feedback resistor value; no external compensation capacitor is needed.

What is the difference between OPA691 and OPA691IDBVT?

The OPA691IDBVT is the SOT-23-6 tape-and-reel variant of the OPA691. The electrical specifications (280 MHz bandwidth, 2100 V/µs slew rate, 5.1 mA supply) are identical; the difference is packaging and reel format.
