Product details
Overview
ADCMP609BRMZ-REEL from Analog Devices is a rail-to-rail, single-supply comparator with 40 ns propagation delay, 1 mW power dissipation at 2.5 V, programmable hysteresis, and shutdown control - designed for high-speed threshold detection in instrumentation and clock restoration circuits.
For engineers reviewing the ADCMP609BRMZ-REEL datasheet, ADCMP609BRMZ-REEL pinout, ADCMP609BRMZ-REEL application, or ADCMP609BRMZ-REEL equivalent, key selection criteria include input common-mode range (−0.2 V to VCC + 0.2 V), TTL/CMOS-compatible dual outputs, 15 pF load timing compliance, and hysteresis programmability via external resistor on HYS pin.
Technical Context
The ADCMP609BRMZ-REEL uses a dual-front-end input stage enabling rail-to-rail operation across −0.2 V to VCC + 0.2 V, with crossover bias points at ~0.8 V and ~1.6 V. Its gain stage delivers 80 dB active gain and 50 dB CMRR over full temperature range.
Propagation delay dispersion is <12 ns across 10–125 mV overdrive, with skew ≤4 ns between Q and Q outputs. The TTL/CMOS output stage drives up to 15 pF while maintaining specified timing and degrades linearly with added capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 30–50 ns at VCC = 2.5 V, 10 mV overdrive - enables sub-25 MHz signal edge detection with deterministic timing. |
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct interface with 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Common-Mode Range | −0.2 V to VCC + 0.2 V - allows detection of signals below ground or above supply, critical for AC-coupled inputs. |
| Hysteresis Control | Programmable 0.1 mV to 160 mV via external resistor on HYS pin - eliminates noise-induced chatter without feedback network parasitics. |
| Shutdown Current | 150–260 µA - reduces system standby power while retaining fast wake-up time (150 ns). |
| Output Drive | TTL-/CMOS-compatible dual outputs (Q/Q) - directly interfaces with one Schottky TTL or three LSTTL loads without buffering. |
| Offset Voltage | ±3 mV typical - ensures accurate threshold detection within ±3 mV error at room temperature. |
Pinout & Package
ADCMP609BRMZ-REEL is housed in an 8-lead MSOP (RM-8) package per JEDEC MO-187-AA, with 0.65 mm pitch and 3.0 mm × 3.0 mm body size. Thermal resistance θJA = 130°C/W in still air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | Accepts 2.5 V to 5.5 V; bypassing with 0.1 µF capacitor near pin is mandatory for stable high-speed operation. |
| VP (Pin 2) | Noninverting analog input | Rail-to-rail capable (−0.2 V to VCC + 0.2 V); low 1 pF input capacitance minimizes signal loading. |
| VN (Pin 3) | Inverting analog input | Matches VP in voltage range and impedance; differential input voltage up to ±(VCC + 0.5 V) tolerated. |
| SDN (Pin 4) | Shutdown control | Logic-low (<0.4 V) disables comparator; sleep current drops to ≤260 µA with 300 ns disable latency. |
| HYS (Pin 5) | Hysteresis bias terminal | 1.25 V internal bias (±0.105 V) with 7 kΩ series resistance; sets hysteresis width via external pull-down resistor. |
| VEE (Pin 6) | Negative supply reference | Internally tied to ground in single-supply mode; must be connected to system ground for proper operation. |
| Q (Pin 7) | Noninverting output | Active-high TTL/CMOS output; VOH = VCC − 0.4 V at 0.8 mA sink, VOL = 0.4 V at 0.8 mA source. |
| Q (Pin 8) | Inverting output | Complementary to Q; enables latch-free differential signaling or OR/NOR logic without external inverters. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with inputs from −0.2 V to VCC + 0.2 V - eliminates need for external clamping or level-shifting in wide-dynamic-range systems. |
| Programmable hysteresis | HYS pin accepts external resistor (30–1200 kΩ) to set hysteresis from 0.1 mV to 160 mV - replaces unstable positive-feedback networks with predictable, layout-insensitive control. |
| Low-glitch TTL/CMOS output | Dual Q/Q outputs switch cleanly with <4.5 ns skew at 2.5 V - enables precise timing capture in dual-edge or differential sampling applications. |
| Fast wake-up from shutdown | 150 ns output-valid wake-up time after SDN transition - supports burst-mode sensing with minimal latency penalty. |
| High PSRR | 60 dB power supply rejection - maintains timing accuracy despite supply ripple up to 100 mVpp on VCC. |
Applications
| High-Speed Instrumentation | Clock/Data Signal Restoration |
|---|---|

IC Role / Device Role / Timing Role: Threshold comparator generating clean digital edges from noisy analog pulses with sub-50 ns timing uncertainty. Use Value: Propagation delay dispersion <12 ns ensures consistent trigger timing across 10–125 mV input overdrive, eliminating jitter in event-driven acquisition. |
Use Scenario: Reconstructing degraded clock or data signals in high-speed serial links, especially after long PCB traces or connectors. IC Role / Device Role / Timing Role: High-speed signal regenerator restoring logic levels and edge integrity before retiming or serialization. Use Value: 40 ns propagation delay and 15 pF load drive capability enable reliable regeneration of >10 MHz square waves without added buffer stages. |
| Logic Level Translation | Peak/Zero-Crossing Detection |
Use Scenario: Interfacing mixed-voltage subsystems (e.g., 2.5 V FPGA I/O driving 5 V actuator control logic). IC Role / Device Role / Timing Role: Bidirectional level shifter using VP/VN as reference inputs and Q/Q as translated outputs. Use Value: Input common-mode range spanning −0.2 V to VCC + 0.2 V allows direct connection to both 2.5 V and 5 V domains without external resistors. |
Use Scenario: Identifying zero crossings in motor phase currents or audio signals for synchronous switching or envelope tracking. IC Role / Device Role / Timing Role: Precision zero-crossing detector with user-adjustable hysteresis to reject noise near threshold. Use Value: Programmable hysteresis (0.1–160 mV) prevents false triggering on EMI-coupled offsets while preserving <50 ns response to true zero crossings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH7220MK/NOPB | 35 ns propagation delay, no shutdown pin, fixed hysteresis only via external feedback; 2.7–12 V supply range. | Lacks integrated shutdown and programmable hysteresis - requires additional components for power gating and noise immunity. | Choose when wider supply range (up to 12 V) is required and shutdown/hysteresis flexibility is not needed. |
| MAX999ESA+ | 4.5 ns propagation delay, rail-to-rail inputs, no hysteresis pin - hysteresis implemented via external resistor network; 2.7–5.5 V supply. | Higher speed but higher power (3.5 mW at 3 V); hysteresis design adds layout sensitivity and parasitic risk. | Choose for ultra-fast (<5 ns) applications where hysteresis can be externally managed and power budget allows. |
Compared with LMH7220MK/NOPB and MAX999ESA+, the ADCMP609BRMZ-REEL uniquely integrates shutdown control, programmable hysteresis via dedicated pin, and guaranteed 40 ns timing at 2.5 V - simplifying board design for battery-powered or noise-sensitive instrumentation.

FAQ
What is the minimum input overdrive required for guaranteed 40 ns propagation delay in ADCMP609BRMZ-REEL?
The ADCMP609BRMZ-REEL achieves its specified 40 ns propagation delay with ≥10 mV input overdrive at VCC = 2.5 V. At lower overdrive levels (e.g., 1–5 mV), delay increases nonlinearly and dispersion rises - so 10 mV is the practical minimum for timing-critical designs using ADCMP609BRMZ-REEL.
Can ADCMP609BRMZ-REEL operate with VEE floating in single-supply mode?
No - Pin 6 (VEE) must be connected to system ground in all single-supply configurations of ADCMP609BRMZ-REEL. Leaving VEE floating violates Absolute Maximum Ratings and risks latch-up or undefined output behavior; grounding VEE establishes the reference for internal biasing and ensures rail-to-rail input functionality.
How does the HYS pin on ADCMP609BRMZ-REEL differ from conventional hysteresis implementation?
Unlike traditional comparators requiring external positive feedback, the ADCMP609BRMZ-REEL's HYS pin provides a 1.25 V internal bias through 7 kΩ series resistance - allowing hysteresis width to be set predictably with a single external resistor. This eliminates feedback loop instability, reduces PCB parasitics, and avoids skew between rising/falling thresholds that plague resistor-divider hysteresis networks.
Is ADCMP609BRMZ-REEL pin-compatible with other devices in the ADCMP60x family?
Yes - ADCMP609BRMZ-REEL shares identical 8-lead MSOP (RM-8) pinout and footprint with ADCMP600, ADCMP601, ADCMP602, ADCMP603, ADCMP604, ADCMP605, ADCMP606, ADCMP607, ADCMP608, and ADCMP609 variants. All support same VCC, VP, VN, SDN, HYS, VEE, Q, Q pin assignments and electrical compatibility within their respective speed/power envelopes.
What is the maximum capacitive load ADCMP609BRMZ-REEL can drive while maintaining 40 ns propagation delay?
The ADCMP609BRMZ-REEL is characterized for 40 ns propagation delay with a 15 pF capacitive load. Driving >15 pF increases delay linearly - e.g., 30 pF adds ~10–15 ns - due to output stage slew limitation. For loads >20 pF, a buffer stage is recommended to preserve ADCMP609BRMZ-REEL's timing performance.
