AD8372ACPZ-WP

Overview

The AD8372ACPZ-WP is a dual, digitally controlled variable gain amplifier from Analog Devices Inc., housed in a 32-lead LFCSP package. It provides precise gain control with a maximum gain of 32 dB and a minimum gain of -9 dB. The device operates on a supply voltage range of 4.5 V to 5.5 V, drawing a typical operating current of 212 mA. It features a 3 dB bandwidth of 130 MHz, an input bias current of 400 nA, and a common-mode rejection ratio of 55 dB. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual channel architecture for simultaneous signal processing
• Digital control interface for precise gain adjustment
• High linearity performance characterized by high IP3
• Low noise figure operation suitable for video applications

Applications

• Dual VGA systems for Cisco equipment
• CATV signal processing
• Video amplifier circuits requiring digital gain control

Procurement Notes

Verify the specific suffix 'WP' against official Analog Devices documentation to confirm it denotes a waffle pack or special packaging variant rather than a functional difference. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the 32-QFN/LFCSP pinout matches the target PCB footprint exactly before procurement.

Selection Notes

Select this component when dual-channel digital variable gain amplification is required for video signals. Compare the 130 MHz bandwidth and 212 mA current consumption against system power budgets. Verify that the digital control interface compatibility aligns with the host controller. Consider the LFCSP-32 package size constraints during mechanical design.

Part Context

This part belongs to the AD8372 series of dual variable gain amplifiers. It is functionally similar to the AD8372ACPZ-R7 but differs in packaging and reel specifications. The 'WP' suffix typically indicates a waffle pack configuration, distinct from the standard tape-and-reel format found in other variants like the -R7 suffix parts.

Replacement Considerations

The AD8372ACPZ-R7 is a direct functional equivalent differing primarily in packaging format (reel vs. waffle). Verify pin compatibility and thermal characteristics when substituting.
