FastFET™ voltage-feedback op-amp for high-speed signal chains
The AD8065ARZ-REEL7 is a single voltage-feedback op-amp from Analog Devices' FastFET™ series, built for applications that demand wide bandwidth and fast settling. Its 145 MHz -3 dB bandwidth and 180 V/µs slew rate suit it for ADC drivers, video distribution, active filters, and high-speed instrumentation front-ends. The rail-to-rail output stage preserves dynamic range in single-supply designs from 5 V to 24 V. Input bias current is just 3 pA, which minimises offset errors in high-impedance sensor interfaces. The part is specified over the industrial temperature range of -40°C to 85°C and comes in an 8-SOIC package — a common footprint that fits existing PCB layouts without re-spin.
Active production — no LTB risk
The AD8065ARZ-REEL7 carries an active product status. There is no last-time-buy notice or end-of-life risk for new designs. The part is ROHS3 compliant, so it meets current environmental regulations for commercial and industrial equipment. For designs that require automotive qualification, the AD8065WARTZ-R7 variant is the AEC-Q100 graded counterpart — same core amplifier, extended temperature range to 105°C, and available in the same 8-SOIC footprint. That alternate shares the same 145 MHz bandwidth and 180 V/µs slew rate, making it a drop-in for automotive sensor conditioning or under-hood signal processing.
