Overview
The ADCMP607BCPZ-R7 is a single-supply, rail-to-rail CML comparator from Analog Devices. It operates on a 2.5 V to 5.5 V supply with a 1.25 ns propagation delay and 2 ps RMS random jitter. The device features split input/output supplies (VCCI/VCCO) for independent swing control. Key specifications include a ±5 mV offset voltage, 50 dB CMRR, and a 12-lead LFCSP package. It includes a shutdown pin and a single-pin LE/HYS control for programmable hysteresis or latch functionality.
Feature Summary
- Features a fully back-matched CML-compatible output stage designed for superior transmission line matching.
- Includes a dedicated shutdown pin for low-power sleep mode operation.
- Provides a single-pin LE/HYS control interface for adjustable hysteresis or high-speed latch acquisition.
- Supports split input and output power supplies without sequencing restrictions.
Applications
- High speed instrumentation
- Clock and data signal restoration
- Logic level shifting or translation
- Pulse spectroscopy
- Automatic test equipment
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the B-grade temperature range covers -40°C to +125°C requirements. Ensure the 12-lead LFCSP footprint matches the design layout. Check for RoHS compliance status in current distributor listings.
Selection Notes
Select this component for applications requiring very fast response times and low jitter. The ADCMP607 is distinct from the ADCMP606 due to its additional latch and hysteresis controls. Verify that the CML output format aligns with downstream receiver inputs. Consider the split supply capability if independent input and output voltage levels are necessary.
Part Context
This part belongs to the ADCMP606/ADCMP607 family of very fast comparators fabricated on Analog Devices' proprietary XFCB2 process. The ADCMP607 variant specifically adds latch and hysteresis capabilities compared to the base ADCMP606 model. Both share similar electrical characteristics but differ in package options and control features.
Replacement Considerations
The ADCMP606BCPZ-R7 serves as a functional substitute if latch and hysteresis features are not required. Ensure the replacement maintains the same 12-lead LFCSP package dimensions for board compatibility.
FAQ
How is hysteresis controlled on the ADCMP607?
Hysteresis is adjusted via the LE/HYS pin using an external pull-down resistor or current source. Leaving the pin floating or driving it high removes hysteresis.
What is the purpose of the split supplies VCCI and VCCO?
Split supplies allow independent control of the input common-mode range and the output voltage swing, providing flexibility for different signal levels without sequencing restrictions.
