Product details
Overview
ADCMP602BRMZ-REEL from Analog Devices is a rail-to-rail, single-supply high-speed comparator with independent input (VCCI) and output (VCCO) supplies, 3.5 ns propagation delay at 2.5 V, 10 mW power dissipation, shutdown control (SDN), and programmable hysteresis/latch via LE/HYS pin - used in clock/data restoration, high-speed trigger circuitry, and ATE systems.
For engineers reviewing the ADCMP602BRMZ-REEL datasheet, ADCMP602BRMZ-REEL pinout, ADCMP602BRMZ-REEL application, or ADCMP602BRMZ-REEL equivalent, key selection considerations include dual-supply flexibility (VCCI/VCCO ±3.0 V differential), −40°C to +125°C operation, TTL/CMOS-compatible output driving up to 5 pF, and verified shutdown wake-up time of 50 ns.
Technical Context
The ADCMP602BRMZ-REEL implements a proprietary XFCB2 process-based comparator core with split supply architecture: VCCI powers the input stage (2.5 V–5.5 V), VCCO powers the output stage (2.5 V–5.5 V), enabling independent signal range and logic swing control. Its input common-mode range extends from −0.2 V to VCCI + 0.2 V, and it features robust overdrive tolerance without phase reversal.
It integrates two distinct control functions on dedicated pins: SDN (Pin 4) enables full device shutdown with 20 ns sleep time and 50 ns wake-up, while LE/HYS (Pin 5) supports either latch mode (low-active) or programmable hysteresis (bias current-controlled, 0.1–120 mV range). Output timing is specified for 10%–90% transitions with ≤500 ps skew between rising/falling edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.5 ns at VCCI = VCCO = 2.5 V, 50 mV overdrive - enables sub-300 MHz timing-critical decision circuits. |
| Supply Range | VCCI: 2.5 V–5.5 V; VCCO: 2.5 V–5.5 V; differential max ±3.0 V - supports mixed-voltage system interfacing without level shifters. |
| Input Common-Mode Range | −0.2 V to VCCI + 0.2 V - allows ground-referenced or negative-going inputs even with single positive supply. |
| Shutdown Current | 400 µA ICCI + 30 µA ICCO at 2.5 V - reduces total system standby power below 500 µA with no external biasing. |
| Hysteresis Range | 0.1 mV to 120 mV (programmable via LE/HYS pin current) - provides noise immunity tunable per signal SNR without external feedback. |
| Output Drive | CMOS/TTL-compatible, drives ≥5 pF with full timing spec - interfaces directly to FPGA I/O, microcontroller GPIO, or logic gates without buffers. |
| Operating Temperature | −40°C to +125°C - qualified for industrial, automotive under-hood, and high-reliability instrumentation environments. |
Pinout & Package
ADCMP602BRMZ-REEL is housed in an 8-lead MSOP package (3.0 mm × 4.9 mm, 0.65 mm pitch) with exposed pad for thermal enhancement. Pin 6 is GND; Pin 1 is VCCI; Pin 8 is VCCO; Pin 4 is SDN (active-low shutdown); Pin 5 is LE/HYS (dual-function latch/hysteresis control).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCCI | Input section supply | Provides bias for analog input stage only; decoupling required separately from VCCO. |
| 2 - VP | Noninverting analog input | Rail-to-rail capable (−0.2 V to VCCI + 0.2 V); 1 pF input capacitance minimizes loading on high-Z sources. |
| 3 - VN | Inverting analog input | Matches VP in voltage range and impedance; differential input voltage up to VCCI + 0.8 V supported. |
| 4 - SDN | Active-low shutdown control | Pulls internal bias currents to near-zero; wake-up valid within 50 ns; VIH ≥ 2.0 V, VIL ≤ 0.6 V. |
| 5 - LE/HYS | Latch enable / hysteresis control | Drives low → latch mode; biased at ~1.25 V → programmable hysteresis; 7 kΩ series resistance enables DAC or resistor control. |
| 6 - GND | Analog/digital ground reference | Single ground pin shared by input/output sections; requires low-inductance PCB return path. |
| 7 - Q | CMOS/TTL-compatible output | Push-pull, rail-to-rail swing; VOH ≥ VCCO − 0.4 V, VOL ≤ 0.4 V @ 8 mA load; degrades gracefully beyond 5 pF. |
| 8 - VCCO | Output section supply | Sets output logic levels independently; allows 2.5 V logic interfacing while input runs at 5 V for dynamic range. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supplies (VCCI/VCCO) | Enables wide input signal range (e.g., −0.5 V to +5.8 V) while maintaining clean 2.5 V CMOS output swing - eliminates level-shifter ICs. |
| Programmable hysteresis via LE/HYS pin | 0.1–120 mV hysteresis set by external current source or resistor - replaces discrete feedback networks and improves jitter stability. |
| Sub-4 ns propagation delay with low dispersion | 3.5 ns typical at 2.5 V, <1.2 ns overdrive dispersion (10–125 mV) - ensures deterministic timing in pulse spectroscopy and ATE sampling. |
| Robust input protection & no phase reversal | Withstands −0.5 V to VCCI + 0.5 V input voltage; output remains valid even when inputs exceed common-mode range - simplifies front-end design. |
| Integrated shutdown with fast wake-up | 20 ns sleep entry, 50 ns wake-up to full output validity - supports burst-mode operation in battery-powered or thermally managed systems. |
Applications
| High-Speed Clock Restoration | Automatic Test Equipment (ATE) |

Use Value: 0.1–120 mV hysteresis range enables wide frequency tuning (kHz to >100 MHz) using simple RC networks and low-drift DACs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX999EXT+T | No independent VCCI/VCCO; single supply only (2.7 V–5.5 V); no shutdown pin; fixed 2 mV hysteresis. | Lacks dual-supply flexibility and power-gating capability - unsuitable for mixed-voltage or low-power burst-mode designs. | Select MAX999EXT+T only when board space is constrained (SOT23-6) and shutdown/hysteresis programmability is unnecessary. |
| TLV3501IDBVR | 3.5 ns delay at 5 V; rail-to-rail input; no shutdown; no latch/hysteresis pin; 2.7 V–5.5 V supply; 1.5 mV offset. | Lower quiescent current (3.5 mA vs. 3.5–4.0 mA), but no hysteresis control or shutdown - requires external circuitry for noise immunity or power management. | Choose TLV3501IDBVR for cost-sensitive, always-on applications where hysteresis is implemented externally and dual supplies are not needed. |
Compared with MAX999EXT+T and TLV3501IDBVR, ADCMP602BRMZ-REEL uniquely delivers independent input/output supplies, active shutdown with 50 ns wake-up, and single-pin programmable hysteresis - enabling higher integration, lower system power, and adaptive noise rejection in compact high-speed designs.

FAQ
What is the minimum recommended bypass capacitance for ADCMP602BRMZ-REEL?
Each supply pin (VCCI and VCCO) requires at least one 0.01 µF high-quality ceramic capacitor placed as close as possible to the pin and connected to GND with redundant vias. A physically short return path for output switching current is essential. ADCMP602BRMZ-REEL performance degrades significantly without proper high-frequency bypassing due to its 3.5 ns propagation delay and sensitivity to supply noise.
Does ADCMP602BRMZ-REEL support true rail-to-rail input operation?
Yes. ADCMP602BRMZ-REEL supports an input common-mode voltage range from −0.2 V to VCCI + 0.2 V, enabling operation with inputs at or slightly below ground and up to 0.2 V above the input supply. This rail-to-rail capability is confirmed across −40°C to +125°C and is process-verified on Analog Devices' XFCB2 technology.
How does the LE/HYS pin function in latch mode versus hysteresis mode on ADCMP602BRMZ-REEL?
When LE/HYS is driven low (≤0.6 V), ADCMP602BRMZ-REEL enters latch mode: the output holds its state until the next valid input transition. When biased at ~1.25 V (e.g., via resistor to VCCO), it enables programmable hysteresis (0.1–120 mV). Both modes coexist - e.g., an open-drain driver can toggle latch while preserving hysteresis bias - as documented in the ADCMP602BRMZ-REEL functional description.
What is the maximum allowable differential supply voltage between VCCI and VCCO for ADCMP602BRMZ-REEL?
The absolute maximum differential voltage between VCCI and VCCO is ±3.0 V during normal operation, and ±5.5 V in nonoperating conditions. Exceeding ±3.0 V during operation risks violating internal bias constraints and may cause timing inconsistency or increased propagation delay dispersion. ADCMP602BRMZ-REEL is explicitly rated for this split-supply margin in its Absolute Maximum Ratings table.
Can ADCMP602BRMZ-REEL drive standard TTL or CMOS logic loads directly?
Yes. ADCMP602BRMZ-REEL features a low-glitch CMOS-/TTL-compatible output stage rated to drive one Schottky TTL or three low-power Schottky TTL loads (or equivalent) with full timing specification. It maintains 3.5 ns propagation delay driving up to 5 pF; larger capacitive loads degrade timing predictably without oscillation, making it suitable for direct interface to FPGAs, microcontrollers, and logic families.
