HA3-2605-5 is listed in the Instrumentation, Op Amps, Buffer Amps range at ChipApex. The manufacturer field lists Intersil. Its product description is IC OPAMP GP 1 CIRCUIT 8DIP. Review the specifications below when checking this part for your BOM.
The HA3-2605-5 is an internally compensated bipolar operational amplifier manufactured by Intersil. It features a bandwidth of 12MHz and high input impedance characteristics. The device is configured as a single general-purpose operational amplifier circuit housed in an 8-pin PDIP package.
Verify the manufacturer designation, specifically checking for Intersil or Harris branding on the component marking. Confirm the package type is 8-PDIP and ensure the part number suffix matches the specific variant requirements. Cross-reference with official Intersil documentation to validate authenticity before procurement.
Select this component when a bipolar op-amp with high input impedance and 12MHz bandwidth is required. Ensure the application supports the 8-PDIP form factor. Verify that the internal compensation meets the stability needs of the target circuit without requiring external components.
This part belongs to the HA-2600/2605 series of internally compensated bipolar operational amplifiers. The series is characterized by coupling very high input impedance with wideband AC performance, designed for precision analog signal processing tasks within the operational amplifier category.
Direct substitutes are not explicitly confirmed in available public data. Evaluate other parts from the HA-2600 series or equivalent bipolar op-amps with similar 12MHz bandwidth and high input impedance specifications if replacement is necessary.
The HA3-2605-5 features very high input impedance, which is a key characteristic of the HA-2600/2605 series.
