ADCMP604BKSZ-R2

Overview

The ADCMP604BKSZ-R2 is a single-channel, very fast analog comparator from Analog Devices Inc., housed in a 6-lead SC-70 package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features rail-to-rail input common-mode capability extending from −0.2 V to VCCI + 0.2 V. The device utilizes an LVDS-compatible output stage with a typical propagation delay of 1.6 ns at 50 mV overdrive. Key electrical specifications include a maximum offset voltage of ±5 mV, a bias current of ±2 µA, and a power supply rejection ratio exceeding 60 dB. It supports operation across an ambient temperature range of −40°C to +125°C.

Feature Summary

• Features a low-glitch LVDS-compatible output stage designed for high-speed signal integrity.
• Provides fully specified rail-to-rail input common-mode voltage range relative to the supply rails.
• Includes a dedicated shutdown pin for controlling device power consumption states.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the datasheet lists multiple options including Reel, Cut Tape, and MouseReel variants for this component family. Confirm the lead frame chip scale package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-supply operation between 2.5 V and 5.5 V is required alongside LVDS interface compatibility. Consider the ADCMP604BKSZ-R2 for applications needing rail-to-rail inputs without external biasing networks. Evaluate the 1.6 ns propagation delay against system timing constraints to ensure it satisfies the necessary response speeds for your specific circuit design.

Part Context

This part belongs to the ADCMP604/ADCMP605 series of comparators fabricated on Analog Devices' proprietary XFCB2 process. While the ADCMP605 offers additional latch and hysteresis control pins in a 12-lead LFCSP package, the ADCMP604 provides a simplified single-channel solution in a compact 6-lead SC-70 package. Both share similar core performance characteristics regarding speed and input ranges.

Replacement Considerations

The ADCMP604BKSZ-REEL7 is a confirmed substitute offering identical electrical specifications but packaged in a reel format instead of cut tape.

FAQ

Does the ADCMP604 support programmable hysteresis?

No, the ADCMP604 does not have a latch/hysteresis control pin; this feature is available only on the ADCMP605 variant.

What is the input common-mode voltage range?

The input common-mode voltage range extends from −0.2 V to VCCI + 0.2 V, allowing for rail-to-rail operation.
