Product Overview
Burr Brown OPA244PA - a precision MicroPower operational amplifier in an 8-pin plastic DIP through-hole package. Part of Burr Brown's MicroAmplifier series, the OPA244PA draws only 50µA quiescent current per channel while supporting supply voltages from 2.2V to 36V single-supply or ±1.1V to ±18V dual-supply. Rail-to-rail output. This part is End-of-Life and no longer in active production - NOS stock is the primary sourcing path for legacy repairs and new low-power designs.

Frequently Asked Questions
What is the difference between the OPA244PA and OPA244UA?
The OPA244PA is an 8-pin through-hole plastic DIP package. The OPA244UA is the surface-mount SO-8 version. Same electrical specifications, different package. Verify your PCB footprint before ordering.
Is this compatible with a single 5V or 3.3V supply?
Yes. The OPA244PA operates on single-supply voltages from 2.2V to 36V, covering both 3.3V and 5V systems directly.
Can this be used in audio or high-speed switching applications?
Not recommended. Bandwidth is 430 kHz and slew rate is 0.1V/µs. This part is optimized for low-power DC and low-frequency signal conditioning, not high-fidelity audio or fast switching circuits.
Is the OPA244PA still in production?
No. This part is End-of-Life and no longer manufactured. New Old Stock is the primary supply path for this through-hole variant.
The OPA244PA is a genuine Burr Brown part. Burr Brown is a prestige analog brand with a history of counterfeits in the secondary market - NOS stock from a verified distributor source is the reliable path for this chip.
