AD8057ARZ

Instrumentation, Op Amps, Buffer Amps Overview

The AD8057ARZ is a single-channel, low-cost, high-performance voltage feedback operational amplifier manufactured by Analog Devices Inc. It features a -3 dB bandwidth of 325 MHz at a gain of +1 and a typical slew rate of 1000 V/µs. The device operates on a wide supply range from 3 V to 12 V with a typical quiescent current of 5.4 mA per amplifier at 5 V. It provides an input voltage noise density of 7 nV/√Hz and maintains total harmonic distortion of -85 dBc at 5 MHz with a 1 kΩ load. The component is housed in an 8-lead SOIC package and supports an industrial operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the procurement channel sources components directly from authorized distributors or verified suppliers to guarantee authenticity. Confirm RoHS compliance status if required by environmental regulations. Validate that the received part matches the AD8057ARZ designation before integration into production lines.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between high speed and low cost is required for video or imaging signal chains. Consider its voltage feedback topology for applications needing predictable gain-bandwidth characteristics. Evaluate the 8-lead SOIC package constraints regarding board space and thermal dissipation. Compare its 5.4 mA supply current against other amplifiers if power efficiency is a critical design parameter.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8057ARZ belongs to the AD8057/AD8058 family of high-speed operational amplifiers designed to reduce the need for qualifying specialty devices. While the AD8058 offers dual channels, the AD8057 provides a single-channel solution in the same compact form factor. This family targets applications requiring high bandwidth and low distortion without the premium cost associated with specialized high-end amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the manufacturer's ordering guide for alternative packaging options such as tape-and-reel variants (e.g., AD8057ARZ-REEL7). Verify pinout compatibility and electrical specifications before substituting with other single-channel high-speed amplifiers.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the maximum capacitive load the AD8057ARZ can drive stably?

The device is stable driving up to 30 pF of capacitive load with 30% overshoot under standard test conditions.

How does the AD8057ARZ handle differential gain and phase errors?

It exhibits very low differential gain error (0.01% to 0.02%) and differential phase error (0.01 to 0.15 degrees) when configured for a gain of +2 with appropriate termination loads.
