Overview
The ADCMP603BCPZ-R2 is a single-channel, rail-to-rail analog comparator from Analog Devices. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device features a propagation delay of 3.5 ns with 50 mV overdrive and consumes 12 mW at 3.3 V. It includes complementary CMOS/TTL-compatible outputs, a shutdown pin, and a latch/hysteresis control pin. The input common-mode range extends from −0.2 V to VCC + 0.2 V. It is housed in a 12-lead LFCSP package and supports operation between −40°C and +125°C.
Feature Summary
- Features fully specified rail-to-rail inputs and outputs for wide signal compatibility.
- Includes a dedicated shutdown pin for low-power sleep mode control.
- Offers programmable hysteresis and latch functionality via a single LE/HYS pin.
- Provides complementary TTL/CMOS-compatible output drivers.
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 reel packaging when sourcing. Confirm RoHS compliance status as Z denotes compliant parts. Ensure the LFCSP-12 footprint matches the PCB design. Check for moisture sensitivity levels if storage conditions are critical. Validate that the operating temperature range meets environmental requirements.
Selection Notes
Select this component for applications requiring fast response times and low power consumption. The split supply architecture allows independent control of input and output voltages. Consider the latch feature for holding signal states. Evaluate the programmable hysteresis for noise immunity. Ensure the load capacitance remains within limits to maintain timing specifications.
Part Context
This part belongs to the ADCMP603 series of very fast comparators. It utilizes XFCB2 proprietary process technology. The series includes variants like ADCMP603BCPZ-R7. It is designed for high-speed time-critical applications. The device offers robust protection against input overdrive.
Replacement Considerations
ADCMP603BCPZ-R7 is a verified alternative with identical electrical characteristics but different reel packaging. Both share the same LFCSP-12 footprint and performance metrics. Verify pinout compatibility before substitution.
