Product details

What this part is and where it fits

The Texas Instruments PGA2320IDW is a two-channel volume control IC controlled via an SPI interface. It accepts a dual supply from ±4.5 V to ±15.5 V.

Supply and temperature — what the ratings mean for the BOM

The ±4.5 V to ±15.5 V supply range means this part runs on the same rails as most op-amp-based analog stages.

Lifecycle and sourcing reality

The PGA2320IDW carries an Active lifecycle status with ROHS3 compliance. No end-of-life notification or last-time-buy windows are in effect.

Frequently asked questions

Is the PGA2320IDW obsolete or still active?

The PGA2320IDW is Active per its lifecycle status. No discontinuation or last-time-buy has been announced. It remains a viable production part.

Can the PGA2320IDW be used with 5 V microcontrollers?

Yes. The SPI logic interface is compatible with 5 V logic levels when the negative supply is at least -4.5 V. A 5 V microcontroller can drive the SPI lines directly without level shifting.

What is the closest pin-compatible alternative to the PGA2320IDW?

The PGA2320IDW is a standalone two-channel SPI volume control. Within the same family, the PGA2311 is a similar dual-channel part but in a DIP-16 package — not pin-compatible with the SOIC-16 footprint. No direct pin-compatible drop-in exists; the PCB layout is specific to the wide-body SOIC.
