Product details
Overview
ADCMP553BRMZ from Analog Devices is a single-supply, high-speed PECL/LVPECL comparator in an 8-lead MSOP package, delivering 500 ps propagation delay, 125 ps overdrive dispersion, and differential latch control for precision timing applications such as high-speed instrumentation front ends and disk drive read channel detection.
For engineers reviewing the ADCMP553BRMZ datasheet, ADCMP553BRMZ pinout, ADCMP553BRMZ application, or ADCMP553BRMZ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative comparators with documented functional and packaging differences.
Technical Context
The ADCMP553BRMZ features a differential input stage with −0.2 V to VCCI − 2.0 V common-mode range and complementary PECL/LVPECL outputs capable of driving 50 Ω loads terminated to VCC − 2 V. Its latch enable inputs include internal pull-ups, enabling transparent operation when left open.
It operates across −40°C to +85°C with dual supply support (VCC = 3.135 V to 5.25 V), achieves >750 MHz equivalent input rise time bandwidth, and delivers 440 ps rise / 410 ps fall times-optimized for sub-nanosecond timing integrity in ATE and logic analyzer signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 500 ps at 1 V overdrive - enables precise edge alignment in <1 ns timing windows |
| Overdrive Dispersion | 75 ps (20 mV–1 V) - ensures consistent timing across varying input amplitudes |
| Rise/Fall Time | 440 ps / 410 ps - supports clean 800 MHz toggle rate without output ringing |
| Input Common-Mode Range | −0.2 V to VCC − 2.0 V - accommodates ground-referenced and negative-biased analog signals |
| Supply Voltage Range | 3.135 V to 5.25 V - compatible with both 3.3 V LVPECL and 5 V PECL systems |
| Power Dissipation | 60–75 mW (with load) - manageable thermal load in dense MSOP layouts |
| Equivalent Input Bandwidth | >750 MHz - preserves fast edge fidelity from source to comparator decision point |
Pinout & Package
ADCMP553BRMZ uses an 8-lead MSOP package (3.0 mm × 3.0 mm, 0.65 mm pitch) with exposed pad for thermal enhancement. Pin assignments are validated per Analog Devices Rev. B datasheet Figure 4 and Table 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | LEA, LEA | Complementary latch enable inputs - active-low latching; internal pull-ups set tracking mode when open |
| 3 | +INA | Noninverting analog input - referenced against −INA for differential comparison |
| 4 | −INA | Inverting analog input - forms matched pair with +INA for low-offset decision |
| 5 | AGND | Analog ground - dedicated return path to minimize noise coupling into sensitive inputs |
| 6 | VCC | Positive supply - powers both input and output stages; supports 3.3 V or 5 V operation |
| 7, 8 | QA, QA | Complementary PECL/LVPECL outputs - drive 50 Ω transmission lines directly to VCC − 2 V |
Key Features
| Feature | Design Value |
|---|---|
| Differential latch control | Enables track-and-hold or sample-and-hold operation without external logic; setup/hold times ≤100 ps |
| Programmable hysteresis | Not applicable - ADCMP553 lacks HYS pin; only ADCMP552 supports programmable hysteresis |
| PECL/LVPECL output compatibility | Direct interface to 3.3 V LVPECL and 5 V PECL logic families with no level-shifting circuitry |
| High PSRR | 70 dB power supply rejection - maintains timing accuracy despite supply ripple up to 100 mV |
| Low overdrive dispersion | 75 ps variation across 20 mV–1 V overdrive - critical for jitter-sensitive ATE trigger paths |
Applications
| Automatic Test Equipment (ATE) | Logic Analyzer Front Ends |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP572BCPZ-REEL7 | Single-channel, 2.5 V supply only; 300 ps propagation delay; 10-pin LFCSP package | Better suited for ultra-low-jitter clock recovery but lacks latch function and dual-supply flexibility | Select when lowest possible propagation delay is required and latch functionality is unnecessary |
| TLV3501CDR | 3.3 V single supply; 4.5 ns propagation delay; SOIC-8 package; CMOS outputs | Lower speed, lower power, no PECL compatibility - suitable for cost-sensitive industrial sensing, not high-speed digital | Select only for non-PECL systems where nanosecond-level timing is sufficient and layout space allows larger SOIC footprint |
Compared with ADCMP553BRMZ, ADCMP572 offers faster propagation but no latch control or dual-supply operation, while TLV3501 trades speed and interface compatibility for cost and power efficiency - making ADCMP553BRMZ the only choice for PECL-based, latch-enabled, sub-ns timing-critical designs in compact MSOP form.

FAQ
What is the maximum operating temperature range for the ADCMP553BRMZ?
The ADCMP553BRMZ is specified for industrial operation from −40°C to +85°C ambient temperature. Junction temperature must not exceed 125°C under continuous operation. Thermal resistance (θJA) is 130°C/W in still air, requiring attention to PCB copper area and airflow in high-power-density layouts. This rating applies to the ADCMP553BRMZ in its 8-lead MSOP package as documented in the Rev. B datasheet Absolute Maximum Ratings table.
Does the ADCMP553BRMZ support programmable hysteresis like the ADCMP552?
No, the ADCMP553BRMZ does not support programmable hysteresis. The HYS pin is present only on the ADCMP552 (20-lead QSOP); the ADCMP553BRMZ omits this feature entirely. Its hysteresis is fixed at ±0.5 mV (typical) per the Rev. B datasheet Table 1. Designers requiring adjustable hysteresis must select ADCMP552 or alternative comparators with dedicated hysteresis control - the ADCMP553BRMZ is optimized for speed and minimal pin count, not adaptive thresholding.
Can the ADCMP553BRMZ operate with separate input and output supply voltages?
No - the ADCMP553BRMZ uses a single positive supply (VCC) for both input and output stages, unlike the dual-supply ADCMP551/ADCMP552 (VCCI/VCCO). Its Rev. B datasheet specifies one supply rail (3.135 V to 5.25 V) powering all circuitry. Attempting independent input/output supplies violates absolute maximum ratings and risks latch-up or parametric failure. The ADCMP553BRMZ simplifies power design by eliminating supply sequencing concerns inherent in dual-rail high-speed comparators.
What is the minimum input pulse width the ADCMP553BRMZ can reliably detect?
The ADCMP553BRMZ guarantees reliable operation down to 700 ps minimum pulse width, as specified in Table 1 under "Minimum Pulse Width" (PWMIN). This value is measured under conditions where propagation delay variation remains below 25 ps. At shorter widths, timing uncertainty increases significantly due to slew-rate-dependent response and input capacitance effects. For robust detection of 700 ps pulses, input slew rate should exceed 1 V/μs per the Applications Information section to avoid oscillation near threshold crossing.
How are the complementary latch enable pins (LEA/LEA) used in the ADCMP553BRMZ?
The ADCMP553BRMZ uses pins 1 and 2 as complementary latch enable inputs (LEA and LEA). When driven differentially - one high, one low - they control transparent vs. latched operation. With internal pull-ups, leaving both pins open defaults to tracking (transparent) mode. Driving them to valid PECL logic levels (VCC − 1.8 V to VCC − 0.8 V) enables precise edge-aligned sampling. Setup and hold times are each ≤100 ps, supporting synchronization with sub-nanosecond clocks. This dual-pin scheme eliminates external inverters needed in single-input latch designs.
