Alternate & Equivalent Parts
Compatible alternatives and drop-in replacements for OPA698ID:
Same current-feedback wideband op-amp family, no disable pin; drop-in for non-gated signal paths
1GHz current-feedback op-amp with comparable slew rate; alternative for high-speed buffer applications
800MHz unity-gain stable op-amp, similar supply range, suitable replacement where lower GBP is acceptable
Frequently Asked Questions
How does the OPA698ID disable function work?
The OPA698ID features a dedicated DISABLE pin. Pulling it low shuts down the amplifier output and reduces supply current to under 1mA, enabling efficient power management in multiplexed or duty-cycled signal chains without removing supply voltage.
Can OPA698ID drive 50-ohm loads directly?
Yes. With a 60mA output current capability and a slew rate of 3500V/µs, the OPA698ID can drive 50Ω back-terminated loads in video or RF applications while maintaining flat frequency response up to hundreds of MHz.
What are the key differences between OPA698ID and OPA695?
OPA698ID includes a hardware disable pin for power gating, making it suitable for multiplexed paths, while OPA695 does not have this feature. Both share current-feedback architecture but OPA698 targets applications requiring controlled enable/disable functionality.
What supply voltage does OPA698ID require?
OPA698ID operates from ±5V to ±15V dual supplies (10V to 30V total). It is optimized at ±5V for low-power systems and at ±15V for maximum output swing, offering flexibility across industrial and telecom designs.
Which package options are available for OPA698?
The OPA698ID comes in an 8-pin SOIC (D) package. TI also offers the OPA698IDBV in a 5-pin SOT-23 for space-constrained layouts, though the SOT-23 variant omits the disable pin.
