AD8063ARZ

Instrumentation, Op Amps, Buffer Amps Overview

The AD8063ARZ is a single-channel, rail-to-rail output voltage feedback amplifier from Analog Devices. It operates on supply voltages ranging from 2.7 V to 8 V and features a typical quiescent current of 6.8 mA per amplifier. The device includes a power-down disable function that reduces the supply current to 400 µA when activated. Key performance specifications include a small-signal bandwidth of up to 320 MHz at a gain of 1, a slew rate of 650 V/µs, and an input offset voltage of 6 mV. It provides excellent video specifications with differential gain error of 0.01% and phase error of 0.04° into a 150 Ω load.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type and ordering suffix against the manufacturer's official documentation before procurement. Confirm that the disabled state logic levels match the system requirements. Ensure thermal management adheres to the absolute maximum ratings provided in the datasheet to prevent permanent damage during operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high speed and low cost in a single-supply environment. The AD8063 is distinct from the AD8061 due to its integrated disable pin. Consider the input common-mode voltage limitations near the positive rail when designing unity-gain circuits. Verify that the capacitive load drive capabilities meet the specific application requirements without additional isolation resistors.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8063ARZ belongs to the AD8061/AD8062/AD8063 family of low-cost, high-speed amplifiers. While the AD8061 offers a single channel and the AD8062 provides dual channels, the AD8063 specifically integrates a disable control pin. All members share similar electrical characteristics, including rail-to-rail outputs and comparable bandwidth, but differ in channel count and power management features.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8061ARZ serves as a functional substitute if the disable pin is not required. The AD8062ARMZ is a dual-channel alternative within the same family. Verify pin compatibility and ensure the absence of the disable feature does not impact system power management strategies.
