The BrownDog™ 140901 is an HA1457 or HA12017 upgrade adapter that integrates one single channel SO8 or 8 pin DIP op amp into a HA1457 pinout in an 8 pin single-inline SIP footprint. The 140901 adapter is designed with a provision for a 5mm radial capacitor between the voltage rail supply pins. With the unique pinout and package of the HA1457, the 140901 adapter provides options when upgrading or replacing HA1457 op amps by allowing a modern, standard single op amp as a viable alternative. When paired with the 140901 adapter, a HA1457 op amp can be replaced with a single channel SO8 or 8 pin DIP-package op amp.

The 140901 is made with contemporary PCB design techniques, software, and manufacturing. With electroless nickel immersion gold (ENIG) surface finish for conductivity and flat surface planarity, any single SO8 or 8 pin DIP op amp mounted to the 140901 will perform within its manufacturer-specified ranges. We provide you the option of buying the 140901 adapter either with an 8 pin DIP socket installed, or with your choice of optional audio op amps installed. If you need a different op amp mounted to this adapter, contact us for a quote. We can source manufacturer-authorized components for your requirements, or install your customer-supplied parts to this adapter.
