ADCMP580BCPZ-WP

Overview

The ADCMP580BCPZ-WP is an ultrafast voltage comparator fabricated on the Analog Devices proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features a CML output driver, 180 ps propagation delay, and 100 ps minimum pulse width. The device operates with ±5 V supplies, supporting a −2 V to +3 V input range. It includes on-chip 50 Ω input terminations, resistor-programmable hysteresis, differential latch control, and >70 dB power supply rejection.

Feature Summary

• Ultrafast SiGe performance with 180 ps propagation delay
• CML output stage designed for direct driving of 50 Ω transmission lines
• Integrated 50 Ω input termination resistors with open-pin capability
• Differential latch control and resistor-programmable hysteresis

Applications

• Automatic test equipment (ATE)
• High speed instrumentation
• Medical imaging and diagnostics
• Clock and data signal restoration

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and supply voltages before procurement. Confirm that the component meets all necessary regulatory standards for the intended application environment.

Selection Notes

Select this comparator for applications requiring high-speed threshold detection and low jitter. The CML output is suitable for direct interfacing with standard transmission lines. Consider the integrated latch feature for sampling applications. Verify that the ±5 V supply requirement aligns with the system power architecture.

Part Context

This component belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast voltage comparators. While the ADCMP580 provides CML outputs, the ADCMP581 offers reduced swing ECL outputs, and the ADCMP582 provides reduced swing PECL outputs. All share the same core SiGe technology and pinout structure within the 16-lead LFCSP package.

Replacement Considerations

Direct functional substitutes within the same family include the ADCMP581BCPZ-WP and ADCMP582BCPZ-WP. These variants differ primarily in their output logic families (NECL and PECL, respectively) while maintaining identical input characteristics and package dimensions.
