Product details

The rail-to-rail output stage lets the part deliver the full supply span into the load, which matters in single-supply designs running from 3.5 V to 12 V. Input bias current sits at 30 pA, so the part is usable with high-impedance sensors or precision integrators where bias current drift would otherwise shift the operating point.

Temperature grade and operating range

The 125°C upper limit is the junction temperature, not just ambient — if the part dissipates significant power at high ambient, derate the output current or add airflow. The CMOS input stage keeps the bias current stable across temperature; the 1.5 mV input offset voltage is a typical figure, so for precision DC applications below 0.5 mV offset, a trim or a chopper-stabilized part would be needed.

The tape-and-reel option suits automated pick-and-place; cut-tape quantities are also available for prototypes.

The active status means standard lead times through distribution — no need to broker or stockpile.

Frequently asked questions

Is OPA2725AIDR a rail-to-rail op-amp?

Yes, the OPA2725AIDR has a rail-to-rail output stage. The input common-mode range is not rail-to-rail — it extends to the negative rail but stops about 1.1 V below the positive rail, so high-side sensing at 3.5 V supply needs a level shift.

What is the OPA2725AIDR equivalent or alternative?

A functional alternative within the same CMOS, rail-to-rail output family is the OPA4374AIPWT, which offers four channels but a lower 6.5 MHz gain-bandwidth and 5 V/µs slew rate. For a closer speed match in a dual-channel package, the TLV9362IDDFR provides 10.6 MHz GBW and 25 V/µs slew rate, though it is a general-purpose rather than CMOS amplifier type. Neither is a pin-for-pin drop-in — verify the package and supply range against your board.
