Product details

110 MHz bandwidth, 170V/µs slew rate — single voltage-feedback amp in SOIC-8

The AD8051ARZ is a single-circuit voltage feedback amplifier from Analog Devices, delivering a -3dB bandwidth of 110 MHz and a 170V/µs slew rate.

Output drive is 45 mA per channel.

Housed in an 8-lead SOIC (0.154" width, 3.90 mm body), the AD8051ARZ ships in a tube — the standard SOIC-8 footprint matches the supplier device package 8-SOIC. Surface-mount assembly with no exposed pad; the thermal path is through the leadframe into the board copper. The tube quantity suits prototype and low-volume builds; for reeled supply, check the -REEL7 variant.

Frequently asked questions

What is the closest functional second-source — AD8054ARUZ-REEL7?

The AD8054ARUZ-REEL7 is a quad-channel variant (four circuits vs one) with a 160 MHz bandwidth and 190 V/µs slew rate, but it comes in a TSSOP-14 package and is supplied on tape-and-reel. The AD8051ARZ is a single-channel SOIC-8 part; they share the voltage-feedback, rail-to-rail topology but differ in channel count, package, and bandwidth. A direct drop-in replacement would require a board spin for the different footprint and channel count.
