Product details

What this single op-amp brings to a BOM

The ADA4098-1BUJZ-R5 is a single-channel general-purpose op-amp. Its 3 V to 50 V supply span covers both low-voltage and industrial rails. The rail-to-rail output preserves dynamic range, and the 195 µA supply current suits loop-powered or battery-operated designs.

Gain bandwidth product of 1.05 MHz and slew rate of 0.85 V/µs are sufficient for audio-band filtering, sensor conditioning up to a few tens of kHz, and slow ADC drivers. The 15 µV typical input offset voltage eliminates the need for external trimming in most precision DC measurements — a real BOM simplification for weigh-scale or thermocouple inputs. Input bias current of 350 pA keeps errors negligible when driving from high-impedance sources like pH probes or photodiodes. Output current capability of 50 mA per channel lets the op-amp directly drive a modest load — a reference input, a small relay coil, or an LED indicator — without a separate buffer transistor.

Housed in a TSOT-6 (SOT-23-6 Thin) surface-mount package, the ADA4098-1BUJZ-R5 fits dense PCB layouts.

Frequently asked questions

Is ADA4098-1BUJZ-R5 obsolete or EOL?

No, the part is listed as Active and ROHS3 compliant. No end-of-life notice has been issued, so it remains suitable for new designs.

Does ADA4098-1BUJZ-R5 have a rail-to-rail output?

Yes, the output type is rail-to-rail, which allows the output to swing close to both supply rails — important for single-supply ADC interfaces and low-voltage signal chains.

What is the equivalent of ADA4098-1BUJZ-R5?

There is no direct pin-compatible second source listed. The ADA4077-1ARZ-R7 is a single op-amp with similar offset (15 µV) and wider bandwidth (3.6 MHz), but it uses a different package (SOIC-8) and lacks rail-to-rail output. The AD8622ARZ-REEL is a dual op-amp with lower supply current (200 µA) and a 560 kHz GBW, also in a different package. Evaluate the specific footprint and feature requirements before substituting.
