The Renesas ISL28230CRZ is a dual-channel, general-purpose operational amplifier in an 8-DFN (3x3) package.
5 µV offset and 20 µA supply — the precision-per-power tradeoff
The headline numbers here are the 5 µV input offset voltage and the 20 µA supply per amplifier. For a general-purpose op-amp, that offset is unusually tight — it means you can amplify a 10 mV thermocouple signal without the op-amp's own error swamping the reading. The 20 µA per channel keeps the total quiescent draw at 40 µA for both amplifiers, which is low enough for a battery-powered data logger that runs for months on a CR2032. The tradeoff is bandwidth: 400 kHz gain-bandwidth and 0.2 V/µs slew rate limit this part to audio-frequency and low-speed control loops, not switching regulators or video buffers.
Package and footprint: 8-DFN with exposed pad
The ISL28230CRZ comes in an 8-VDFN exposed-pad package (3x3 mm body). The pad also carries the die's substrate, so leaving it floating can couple switching noise into the amplifier.
Temperature grade: commercial only
If the design needs to operate below freezing or above 70°C — outdoor telecom, automotive cabin, or engine-bay-adjacent — the ISL28230IRZ is the industrial-temperature (-40°C to 125°C) sibling. The two are otherwise pin-compatible and share the same core parametric table.
