Product details
Overview
ADCMP602BRMZ-REEL7 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, programmable hysteresis via LE/HYS pin, and dedicated shutdown (SDN) control. It operates from −40°C to +125°C and delivers TTL/CMOS-compatible output drive up to 5 pF load in clock restoration and high-speed threshold detection.
For engineers reviewing the ADCMP602BRMZ-REEL7 datasheet, ADCMP602BRMZ-REEL7 pinout, ADCMP602BRMZ-REEL7 application, or ADCMP602BRMZ-REEL7 equivalent, this page provides verified pin functions, real-world timing behavior under overdrive and common-mode variation, MSOP-8 package thermal resistance (θJA = 130°C/W), and validated alternatives for latch-enabled, low-glitch comparator designs requiring split-supply flexibility.
Technical Context
The ADCMP602BRMZ-REEL7 implements a dual-supply architecture with separate VCCI (input section) and VCCO (output section) pins, enabling independent voltage control and eliminating supply sequencing constraints. Its input stage supports common-mode range from −0.2 V to VCCI + 0.2 V and differential input up to VCCI + 0.8 V.
It integrates a single-pin LE/HYS terminal that simultaneously enables latch mode (when driven low) and adjusts hysteresis (via external resistor or current source), with bias voltage ~1.25 V and series resistance ~7 kΩ. The SDN pin provides full shutdown with 20 ns sleep time and 50 ns wake-up time, reducing ICCI to 240–400 µA and ICCO to 30 µA at 2.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.5 ns at VOD = 50 mV, VCCI = VCCO = 2.5 V - enables sub-300 MHz signal sampling with minimal timing uncertainty. |
| Supply Range | VCCI: 2.5 V to 5.5 V; VCCO: 2.5 V to 5.5 V - supports split-supply operation (e.g., VCCI = 3.3 V, VCCO = 1.8 V) without sequencing. |
| Input Common-Mode Range | −0.2 V to VCCI + 0.2 V - allows direct interfacing with negative-going signals or ground-referenced sources. |
| Output Drive | TTL/CMOS-compatible, drives ≥5 pF with full timing specs - eliminates need for external buffers in logic-level translation. |
| Shutdown Current | ICCI ≤ 400 µA, ICCO ≤ 30 µA at 2.5 V - reduces system standby power while retaining fast wake-up (<50 ns). |
| Hysteresis Control | LE/HYS pin sets hysteresis from 0.1 mV (RHYS = ∞) to 160 mV (RHYS ≈ 10 kΩ) - replaces discrete feedback networks with predictable, stable adjustment. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood and industrial motor-control environments. |
Pinout & Package
The ADCMP602BRMZ-REEL7 is housed in an 8-lead MSOP package (3.0 mm × 3.0 mm, 0.65 mm pitch) with θJA = 130°C/W in still air. Thermal performance supports continuous operation at full speed in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCCI | Input Section Supply | Power domain for analog input stage only; may differ from VCCO to isolate noise-sensitive inputs. |
| 2 - VP | Noninverting Analog Input | Rail-to-rail capable input with −0.2 V to VCCI + 0.2 V common-mode range; no phase reversal on overdrive. |
| 3 - VN | Inverting Analog Input | Matches VP in voltage range and protection; differential input withstands ±(VCCI + 0.5 V). |
| 4 - SDN | Shutdown Control | Active-low enable: VIH ≥ 2.0 V, VIL ≤ 0.4 V; asserts shutdown within 20 ns, releases output within 50 ns. |
| 5 - LE/HYS | Latch Enable / Hysteresis Control | Drives low for latch mode; biased at ~1.25 V for hysteresis programming; logic threshold ~1.1 V independent of VCC. |
| 6 - GND | Analog Ground Reference | Common return for input and output sections; requires low-inductance connection to minimize switching noise coupling. |
| 7 - Q | Noninverting Output | CMOS/TTL-compatible push-pull output; VOH ≥ VCCO − 0.4 V, VOL ≤ 0.4 V at 8 mA load. |
| 8 - VCCO | Output Section Supply | Defines output logic swing and drive strength; decoupled separately from VCCI for optimal noise isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Independent VCCI/VCCO supplies | Enables flexible I/O voltage translation (e.g., 3.3 V input → 1.8 V logic output) without level shifters or sequencing delays. |
| Single-pin LE/HYS control | Eliminates separate latch and hysteresis pins-reduces PCB routing complexity and supports dynamic hysteresis tuning in ATE systems. |
| Low-glitch CMOS/TTL output | Guarantees monotonic transitions even under heavy capacitive loading, preventing false triggering in clock recovery circuits. |
| Robust input overdrive tolerance | Withstands −0.5 V to VCCI + 0.5 V at inputs without damage or phase reversal-simplifies front-end protection design. |
| Sub-2 ns overdrive dispersion | Propagation delay varies <1.2 ns across 10–125 mV overdrive-critical for time-of-flight and pulse-width measurement accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP601BRJZ-REEL7 | 6-lead SC70; lacks SDN pin; shares same LE/HYS functionality and 3.5 ns delay. | No shutdown capability; unsuitable for power-gated systems requiring rapid sleep/wake cycles. | Select when board space is constrained and shutdown is unnecessary. |
| MAX999EXT+T | 5-lead SOT23; no independent VCCI/VCCO; fixed 2 mV hysteresis; 4.5 ns typical delay. | Cannot support split-supply operation or programmable hysteresis; lower temperature grade (−40°C to +85°C). | Select only for cost-sensitive, single-supply legacy designs where latch/hysteresis flexibility is not required. |
Compared with ADCMP601BRJZ-REEL7, the ADCMP602BRMZ-REEL7 adds shutdown control and MSOP-8 layout flexibility; compared with MAX999EXT+T, it delivers superior timing precision, wider temperature range, and configurable hysteresis-making it the preferred choice for next-generation ATE and instrumentation platforms.

FAQ
What is the minimum recommended bypass capacitance for ADCMP602BRMZ-REEL7?
ADCMP602BRMZ-REEL7 requires at least one 0.01 µF high-quality ceramic capacitor placed as close as possible to each of the VCCI and VCCO pins, connected to GND with redundant vias. This minimizes high-frequency supply impedance and ensures stable 3.5 ns propagation delay performance. Additional bulk capacitance (e.g., 1 µF) may be added nearby but does not replace the critical high-frequency bypassing.
Does ADCMP602BRMZ-REEL7 support true rail-to-rail input operation?
Yes, ADCMP602BRMZ-REEL7 supports rail-to-rail input operation with a common-mode range from −0.2 V to VCCI + 0.2 V. This allows direct interface with signals referenced below ground or exceeding VCCI, such as AC-coupled sources or negative-going transients, without external level shifting.
How does the LE/HYS pin function in latch mode versus hysteresis mode?
In latch mode, driving the LE/HYS pin low captures and holds the comparator output state until the next valid input transition. In hysteresis mode, applying a bias current or resistor to LE/HYS sets hysteresis from 0.1 mV to 160 mV. Both modes coexist: a three-state driver can toggle latch while preserving hysteresis programming, as confirmed in the ADCMP602BRMZ-REEL7 datasheet Figure 26.
Can ADCMP602BRMZ-REEL7 operate with VCCI = 3.3 V and VCCO = 1.8 V?
Yes, ADCMP602BRMZ-REEL7 explicitly supports independent VCCI and VCCO supplies ranging from 2.5 V to 5.5 V each, with a maximum differential of ±3.0 V during operation. A configuration of VCCI = 3.3 V and VCCO = 1.8 V is fully compliant and enables direct interfacing with 3.3 V sensors and 1.8 V logic domains without level shifters.
What is the guaranteed propagation delay variation across temperature for ADCMP602BRMZ-REEL7?
ADCMP602BRMZ-REEL7 guarantees propagation delay of 3.5 ns (typical) at 25°C with 50 mV overdrive and VCCI = VCCO = 2.5 V. Over the full −40°C to +125°C range, delay increases by ≤0.8 ns, remaining ≤4.3 ns at 5.5 V supply and worst-case conditions-verified in Table 1 and Figure 14 of the official datasheet.
