4.5 MHz GBP with 900 µA supply — the power-budget sweet spot
The Renesas ISL28148FHZ-T7A is a single-channel general-purpose op-amp that balances a 4.5 MHz gain bandwidth product with a 900 µA supply current, making it a fit for signal conditioning in battery-powered or thermally constrained designs. Rail-to-rail output swing preserves dynamic range at low supply voltages, while the 4 V/µs slew rate handles fast pulse edges without excessive distortion. Input bias current sits at 1 pA, so high-impedance sensors like photodiodes or pH probes see negligible loading. Output can source or sink 75 mA, enough to drive an ADC input or a small analog multiplexer. Housed in a SOT-23-6, it fits tight PCB layouts common in portable instruments, sensor modules, and industrial control I/O.
Temperature range and environment
The wide temperature range also covers cold-crank and hot-soak conditions in automotive modules without needing a separate commercial-grade variant.
Lifecycle and sourcing posture
No official second-source or direct replacement is listed in the Renesas cross-reference, so dual-sourcing would require qualifying a functionally similar op-amp from another vendor.
