AD8330ACPZ-R2

Instrumentation, Op Amps, Buffer Amps Overview

The AD8330ACPZ-R2 is a low-cost, wideband variable gain amplifier from Analog Devices Inc. It features a fully differential signal path with rail-to-rail outputs and operates on a single supply voltage ranging from 2.7 V to 6 V. The device provides a linear-in-dB gain range of 0 dB to 50 dB controlled by the VDBS pin, or a linear-in-magnitude mode via the VMAG pin. It maintains a constant bandwidth of 150 MHz across all gain settings. Key electrical parameters include a typical quiescent current of 20 mA, an input offset voltage of 1 mV, and a slew rate of 1500 V/µs. It is housed in a space-saving 16-lead LFCSP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides a fully differential signal path suitable for driving ADCs or cable drivers while supporting single-ended inputs.
• Features a constant bandwidth of 150 MHz that remains stable regardless of the selected gain setting.
• Offers dual control interfaces allowing users to select between linear-in-dB gain scaling and linear-in-magnitude amplification.
• Includes an optional automatic offset compensation loop to minimize DC errors in precision applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Pre-ADC signal conditioning
• Automatic Gain Control (AGC) amplifiers
• 75 Ω cable driving adjust

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix R2 indicates reel packaging when sourcing. Confirm the LFCSP-16 footprint matches your PCB layout requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system environment. Check for RoHS compliance documentation if required by your manufacturing standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a wide dynamic range and consistent high-frequency response are critical. It is ideal for applications requiring precise gain control without bandwidth variation. Consider the differential output architecture if noise immunity is a priority over single-ended simplicity.

Instrumentation, Op Amps, Buffer Amps Part Context
