Dual voltage-feedback amp with 110 MHz bandwidth and rail-to-rail output
The AD8092ARMZ from Analog Devices is a dual voltage-feedback operational amplifier in an 8-MSOP surface-mount package. It delivers a -3dB bandwidth of 110 MHz and a slew rate of 170 V/µs, making it suited for high-speed signal conditioning, video amplification, and ADC driver stages where fast settling and wide dynamic range are required. The rail-to-rail output stage maximizes headroom in single-supply designs operating from 3 V to 12 V. Each channel draws 4.8 mA supply current, a moderate figure for this speed class. The part is rated over the industrial temperature range of -40°C to 85°C.
Slew rate and bandwidth — what they mean for signal fidelity
The 170 V/µs slew rate determines the maximum large-signal frequency before slew-rate limiting sets in. The 110 MHz small-signal bandwidth applies at lower amplitudes.
Supply range and output drive
The amplifier operates from a single 3 V supply up to 12 V. The rail-to-rail output preserves dynamic range in low-voltage systems.
