ADCMP607BCPZ-R2

Overview

The ADCMP607BCPZ-R2 is a single-supply, rail-to-rail comparator fabricated on the XFCB2 process. It features a CML-compatible output stage with a propagation delay of 1.25 ns and 2 ps rms random jitter. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V, with an input common-mode range extending from −0.2 V to VCCI + 0.2 V. It includes a shutdown pin and a dedicated LE/HYS pin for programmable hysteresis and latch control. Power dissipation is typically 50 mW at 2.5 V.

Feature Summary

• Features a CML-compatible output stage designed for high-speed transmission line driving.
• Includes a dedicated LE/HYS pin enabling programmable hysteresis and latch functionality via a single control interface.
• Incorporates a shutdown pin for low-power standby operation.
• Supports split input/output supplies (VCCI and VCCO) without sequencing restrictions.

Applications

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

Procurement Notes

Verify the specific suffix R2 indicates tape and reel packaging when sourcing. Confirm that the LE/HYS and SDN pins are utilized correctly for hysteresis adjustment and power management respectively. Ensure supply voltages remain within the specified 2.5 V to 5.5 V range to maintain electrical characteristics. Check thermal resistance specifications for the LFCSP package during layout planning.

Selection Notes

Select this component for applications requiring very fast response times and low jitter in a compact surface-mount package. The ADCMP607 is distinct from the ADCMP606 due to its additional latch and hysteresis control capabilities. Consider the CML output requirements for termination networks. Evaluate the need for split supplies if independent output swing control is necessary for the target logic family.

Part Context

This part belongs to the ADCMP606/ADCMP607 series of very fast comparators manufactured by Analog Devices Inc. These devices utilize a proprietary XFCB2 process to achieve high performance in small packages. The ADCMP607 variant specifically adds latch and hysteresis features not present in the ADCMP606 model.

Replacement Considerations

The ADCMP607BCPZ-R7 is a direct substitute with identical electrical specifications but different packaging format.

FAQ

How is hysteresis controlled on the ADCMP607?

Hysteresis is controlled via the LE/HYS pin. Connecting an external pull-down resistor or current source to this pin varies the hysteresis amount predictably.

What is the function of the VEE pin?

The VEE pin serves as the negative supply voltage connection for the input stage, allowing for rail-to-rail input operation.
