Replacement verdict
Compatible functional replacement candidate
The AD8052ARZ and AD8052LVISO8X are both dual high-speed voltage-feedback operational amplifiers from Analog Devices sharing the same core AD8052 architecture, making the LVISO8X a viable functional substitute for the ARZ in most designs. The primary distinction is package and grade: the ARZ is supplied in an 8-lead SOIC, while the LVISO8X is an automotive-qualified SOIC variant, so footprint compatibility and qualification requirements should be confirmed against the target application before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8052ARZ | AD8052LVISO8X | Why it matters |
|---|---|---|---|
| Supply Voltage Range | 3 V to 12 V (±1.5 V to ±6 V) | 2.5 V to 5.5 V (single supply) | The LV variant is optimized for low-voltage single-supply operation, so it cannot be used at the higher supply voltages supported by the standard AD8052ARZ. |
| -3 dB Bandwidth | 145 MHz (G = +1) | 80 MHz (G = +1) | Bandwidth determines the maximum signal frequency the amplifier can handle; the standard version offers roughly twice the small-signal bandwidth. |
| Slew Rate | 140 V/µs | 50 V/µs | Slew rate limits large-signal response and distortion at high frequencies; the LV part is significantly slower, affecting pulse and high-frequency performance. |
| Supply Current per Amplifier | 5.5 mA typ | 2.5 mA typ | Lower quiescent current in the LV version reduces power consumption, which is critical in portable and battery-powered designs. |
| Input Voltage Noise | 6 nV/√Hz | 10 nV/√Hz | Lower input noise improves signal-to-noise ratio in low-level signal applications; the standard version is quieter. |
| Output Voltage Swing | Rail-to-rail output | Rail-to-rail output | Both offer rail-to-rail output, but the achievable swing depends on the supply voltage, which differs between the two parts. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Identical package and pinout allow drop-in board compatibility, though electrical differences still require verification. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +85 °C | The narrower temperature range of the LV version may limit use in harsh or high-temperature environments. |

Frequently asked questions
What are the key differences between the AD8052ARZ and AD8052LVISO8X?
The AD8052ARZ is a dual, low-cost, high-speed voltage feedback operational amplifier in an 8-lead SOIC package, specified for operation on ±5 V or +5 V supplies with a typical −3 dB bandwidth of 145 MHz and 170 V/µs slew rate. The AD8052LVISO8X is a dual, low-power, high-speed voltage feedback amplifier in an 8-lead SOIC package optimized for single-supply operation from +3 V to +12 V, with a typical −3 dB bandwidth of 80 MHz and 140 V/µs slew rate. The AD8052LVISO8X is specified for lower supply voltage operation and lower quiescent current than the AD8052ARZ.
Are the AD8052ARZ and AD8052LVISO8X pin-compatible?
Yes. Both devices are dual operational amplifiers offered in the standard 8-lead SOIC (SOIC_N) package with the same industry-standard pinout: 1OUT, 1IN−, 1IN+, V−, 2IN+, 2IN−, 2OUT, and V+. This allows the AD8052LVISO8X to be placed on a PCB footprint designed for the AD8052ARZ, provided the supply voltage and performance requirements are validated for the target design.
What supply voltage ranges do the AD8052ARZ and AD8052LVISO8X support?
The AD8052ARZ is specified for dual supplies of ±5 V and single supply of +5 V, with an absolute maximum supply voltage of 12 V. The AD8052LVISO8X is specified for single-supply operation from +3 V to +12 V and is optimized for low-voltage single-supply applications. The AD8052LVISO8X should not be operated at the higher dual-supply voltages used with the AD8052ARZ without verifying against the manufacturer datasheet absolute maximum ratings.
How do the bandwidth and slew rate of the AD8052ARZ and AD8052LVISO8X compare?
The AD8052ARZ provides a typical −3 dB bandwidth of 145 MHz and a slew rate of 170 V/µs at ±5 V. The AD8052LVISO8X provides a typical −3 dB bandwidth of 80 MHz and a slew rate of 140 V/µs. The AD8052ARZ therefore offers higher small-signal bandwidth, while the AD8052LVISO8X trades bandwidth for lower supply voltage operation and reduced power consumption.
How does quiescent current compare between the AD8052ARZ and AD8052LVISO8X?
The AD8052ARZ typically draws approximately 5.5 mA per amplifier (about 11 mA total for the dual) at ±5 V. The AD8052LVISO8X is designed for lower power consumption, typically drawing approximately 2.5 mA per amplifier (about 5 mA total for the dual). The AD8052LVISO8X is therefore preferable for power-sensitive, single-supply designs.
Can the AD8052LVISO8X directly replace the AD8052ARZ in an existing ±5 V design?
Not without validation. Although the pinout and package are compatible, the AD8052LVISO8X is specified for single-supply operation from +3 V to +12 V and is not characterized for ±5 V dual-supply operation in the same manner as the AD8052ARZ. The designer must verify supply voltage limits, input common-mode range, output swing, bandwidth, and slew rate against the AD8052LVISO8X datasheet before substituting it in a ±5 V circuit.
Which device is better suited for low-voltage single-supply applications?
The AD8052LVISO8X is specifically optimized for low-voltage single-supply operation from +3 V to +12 V and features lower quiescent current, making it the more appropriate choice for portable and low-power single-supply systems. The AD8052ARZ is specified primarily for ±5 V and +5 V operation and is better suited to applications requiring higher bandwidth and slew rate at those supply levels.
Do both the AD8052ARZ and AD8052LVISO8X come in the same package type?
Yes. Both the AD8052ARZ and AD8052LVISO8X are supplied in the 8-lead SOIC (SOIC_N) package. The "ARZ" and "LVISO8X" suffixes denote the specific grade and packaging option from the manufacturer, but the physical package family and pin count are the same, enabling footprint reuse when electrical requirements are satisfied.
