AD8056AR

Instrumentation, Op Amps, Buffer Amps Overview

The AD8056AR is a dual-channel, low-cost voltage feedback amplifier manufactured by Analog Devices. It provides high-speed performance with a 300 MHz gain bandwidth product and a 1400 V/µs slew rate at unity gain. The device operates on supply voltages ranging from ±4.0 V to ±6.0 V, drawing a typical quiescent current of 10 mA per channel. It features a maximum input offset voltage of 5 mV and an input bias current of 1.2 µA. The amplifier delivers over 60 mA of output drive current and is housed in an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The AD8056AR designation indicates an 8-lead SOIC package with an operating temperature range of -40°C to +125°C. Confirm RoHS compliance status if required, as indicated by potential 'Z' suffixes in related part numbers. Ensure the selected variant matches the required reel or tube packaging configuration for manufacturing integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution is required alongside the single-channel AD8055. The AD8056AR is appropriate for designs needing two independent high-speed amplifiers in a compact surface-mount package. Consider the 10 mA quiescent current per channel for total power budget calculations. Verify that the 8-lead MSOP (AD8056ARM) is not preferred over the standard SOIC for space constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8056AR belongs to the AD8055/AD8056 family of low-cost, high-speed voltage feedback amplifiers. While the AD8055 provides a single channel, the AD8056 integrates two identical channels within a single package. Both devices share similar electrical characteristics, including 300 MHz bandwidth and 1400 V/µs slew rate, designed to compete with current feedback amplifiers while maintaining the stability and ease of use associated with voltage feedback topologies.
