AD8465WBCPZ-R7

Overview

The AD8465WBCPZ-R7 is a single-channel, very fast analog comparator fabricated on the Analog Devices XFCB2 process. It operates with a supply voltage range of 2.5 V to 5.5 V and features rail-to-rail input common-mode capability from −0.2 V to VCCI + 0.2 V. The device provides LVDS-compatible outputs with a propagation delay of 1.6 ns and low jitter. Key electrical parameters include an offset voltage of ±5 mV, bias current of ±2 µA, and power dissipation of 37 mW at 2.5 V. It includes dedicated pins for shutdown control and programmable hysteresis/latch functionality.

Feature Summary

• Features a low glitch LVDS-compatible output stage designed to drive standard LVDS inputs directly.
• Includes a flexible power supply scheme allowing split input/output supplies or single-supply operation without sequencing restrictions.
• Offers a unique single-pin control option for both programmable hysteresis and latch functions.
• Provides robust protection against large input overdrive with no phase reversal when valid input ranges are exceeded.

Applications

• High speed instrumentation
• Clock and data signal restoration
• Logic level shifting or translation
• Automatic test equipment (ATE)
• Pulse-width modulators

Procurement Notes

Verify that the specific part number suffix matches the required automotive qualification status, as indicated by the 'W' designation in the ordering guide. Confirm package type consistency with the 12-lead LFCSP specification. Ensure environmental operating temperature requirements align with the specified -40°C to +125°C range before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring sub-nanosecond propagation delay and low jitter performance. Consider the separate VCCI and VCCO supply pins if split supply operation is needed to optimize power consumption or accommodate specific input signal ranges. Evaluate the need for the integrated latch and hysteresis features to simplify external circuit design compared to standard comparators lacking these controls.

Part Context

This device belongs to the AD8465 series of high-speed comparators manufactured by Analog Devices Inc. It utilizes proprietary XFCB2 technology to achieve its performance metrics. The product line includes variants qualified for automotive applications, distinguished by specific ordering suffixes. The family focuses on providing versatile signal conditioning with integrated control features for high-frequency digital interfaces.

Replacement Considerations

The AD8465WBCPZ-WP is a verified substitute within the same series offering identical specifications and automotive qualification. Both parts utilize the 12-lead LFCSP package. Designers should verify that any replacement maintains the specific LVDS output characteristics and supply voltage compatibility required by the existing circuit topology.
