ADCMP580BCPZ-R2

Overview

The ADCMP580BCPZ-R2 is an ultrafast voltage comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features a CML output driver designed to directly drive 400 mV into 50 Ω transmission lines terminated to ground. The device operates with ±5 V power supplies, providing a wide −2 V to +3 V input range. Key performance specifications include a propagation delay of 180 ps, 100 ps minimum pulse width, and 8 GHz equivalent input rise time bandwidth.

Feature Summary

• Ultrafast SiGe construction enabling high-speed signal processing
• Integrated 50 Ω on-chip termination resistors at both input pins
• Resistor-programmable hysteresis for noise immunity control
• Differential latch control inputs for signal acquisition

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 current documentation to confirm package type and reel specifications. Ensure that the required supply voltages and termination potentials match the system design requirements before procurement. Cross-reference the datasheet revision to confirm all electrical parameters are consistent with the intended application environment.

Selection Notes

Select this component when ultrafast propagation delay and low jitter are critical. The ADCMP580 variant specifically provides CML outputs suitable for direct connection to standard transmission lines. Consider the ADCMP581 or ADCMP582 if NECL or PECL logic levels are preferred instead. Verify that the operating temperature range meets the environmental constraints of the deployment site.

Part Context

This part belongs to the ADCMP580/ADCMP581/ADCMP582 family of ultrafast SiGe voltage comparators. While sharing identical core comparator characteristics, the family members differ in their output driver types: CML, reduced swing ECL, and reduced swing PECL respectively. All variants utilize the same 16-lead LFCSP package and share the same internal architecture.

Replacement Considerations

Direct functional replacements within the same family include the ADCMP581BCPZ-R2 and ADCMP582BCPZ-R2, provided the output logic level differences are accommodated by the downstream circuitry.
