Overview
The ADCMP553BRMZ is a single-supply, high-speed comparator fabricated on Analog Devices' proprietary XFCB process. It features a 500 ps typical propagation delay with less than 125 ps overdrive dispersion. The device provides differential PECL/LVPECL compatible outputs capable of driving 50 Ω transmission lines. It includes a latch input for track-and-hold or sample-and-hold modes and operates within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Differential latch control enables tracking, track-and-hold, or sample-and-hold operation modes.
- Outputs are fully compatible with PECL and 3.3 V LVPECL logic families.
- Internal latch pull-up resistors set the latch in tracking mode when inputs are left open.
Applications
- Automatic test equipment
- High speed instrumentation
- Window comparators
- Threshold detection
- Zero crossing detectors
Procurement Notes
Verify the specific ordering suffix 'BRMZ' corresponds to the 8-lead MSOP package variant. Confirm that the supply voltage requirements align with the specified dual supply configuration (VCCI/VCCO) rather than a single rail setup if applicable to the design. Ensure the component meets the required industrial temperature specifications for the intended environment.
Selection Notes
Select this component for applications requiring minimal propagation delay variation across different input overdrive levels. The differential output stage supports direct interfacing with standard high-speed logic families without additional buffering. Consider the 8-lead MSOP package constraints regarding thermal resistance and board layout space compared to larger QSOP packages available in the series.
Part Context
This part belongs to the ADCMP551/ADCMP552/ADCMP553 family of single-supply high-speed comparators. While the ADCMP551 uses a 16-lead QSOP and the ADCMP552 uses a 20-lead QSOP with programmable hysteresis, the ADCMP553 utilizes an 8-lead MSOP package. All variants share the same core high-speed performance characteristics and XFCB fabrication technology.
Replacement Considerations
Public confirmed substitute part numbers: None identified.
