Product details
Overview
ADCMP600BKSZ-R2 from Analog Devices is a rail-to-rail, single-supply TTL/CMOS comparator in SC70-5 package, delivering 3.5 ns propagation delay at 2.5 V supply, ±2 mV input offset voltage, and −0.2 V to VCC + 0.2 V input common-mode range. It operates from 2.5 V to 5.5 V, features low-glitch CMOS/TTL output, and supports high-speed threshold detection in instrumentation and clock restoration.
For engineers reviewing the ADCMP600BKSZ-R2 datasheet, ADCMP600BKSZ-R2 pinout, ADCMP600BKSZ-R2 application, or ADCMP600BKSZ-R2 equivalent, key selection considerations include propagation delay dispersion (<1.2 ns over 10–125 mV overdrive), latch-free hysteresis control (2 mV fixed), shutdown absence (vs. ADCMP602), and SC70-5 thermal resistance (426°C/W).
Technical Context
The ADCMP600BKSZ-R2 uses Analog Devices' XFCB2 process for high-speed analog comparison with robust input overdrive tolerance and no phase reversal beyond valid input range. Its input stage supports GND −0.5 V to VCC + 0.2 V common-mode voltage and exhibits 85 dB active gain with 50 dB PSRR and CMRR.
Unlike ADCMP601/602, it lacks LE/HYS and SDN pins-hysteresis is fixed at 2 mV and no shutdown capability exists. The shared VCCI/VCCO supply pin simplifies single-rail operation but eliminates independent input/output supply control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.5 ns at 50 mV overdrive, 2.5 V supply - enables sub-300 MHz timing-critical decisions. |
| Input Offset Voltage | ±2 mV typical - ensures accurate threshold detection down to ~10 mV signal margins. |
| Supply Range | 2.5 V to 5.5 V single supply - compatible with modern low-voltage logic and mixed-signal systems. |
| Input Common-Mode Range | −0.2 V to VCC + 0.2 V - supports rail-to-rail sensing including below-GND signals. |
| Output Drive | TTL/CMOS-compatible, drives ≥5 pF - interfaces directly with FPGA I/O, microcontroller inputs, and logic families without buffering. |
| Power Dissipation | 7–9 mW at 2.5 V - enables dense placement in thermally constrained high-speed PCBs. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
ADCMP600BKSZ-R2 is housed in a 5-lead SC70 package (JEDEC MO-203AA), with θJA = 426°C/W in still air. Pin 1 is Q (noninverting output), Pin 2 is GND, Pin 3 is VP (noninverting input), Pin 4 is VN (inverting input), and Pin 5 is VCCI/VCCO (shared input/output supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q) | Noninverting Output | Active-high CMOS/TTL output; logic high when VP > VN; drives loads up to 5 pF with full timing spec. |
| 2 (GND) | Negative Supply Reference | Return path for both input and output sections; must be low-inductance plane for <3.5 ns timing integrity. |
| 3 (VP) | Noninverting Analog Input | Accepts −0.5 V to VCC + 0.2 V; differential input voltage up to VCC + 0.8 V; no phase reversal on overdrive. |
| 4 (VN) | Inverting Analog Input | Same voltage range as VP; matched bias current (±2 µA) enables precision differential sensing. |
| 5 (VCCI/VCCO) | Shared Supply Pin | Single-pin power for both input and output stages; eliminates need for dual supplies but couples noise between sections. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Operates with inputs from −0.2 V to VCC + 0.2 V - enables direct interface with sensors and DACs without level-shifting. |
| Low-glitch output stage | Minimizes false triggering in high-speed clock/data recovery - critical for pulse spectroscopy and ATE. |
| Fixed 2 mV hysteresis | Eliminates external feedback components while suppressing noise-induced chatter near threshold. |
| 50 dB PSRR/CMRR | Rejects supply and common-mode noise - maintains timing accuracy in noisy mixed-signal PCBs. |
| −40°C to +125°C operation | Validated performance across full industrial temperature range - no derating required for embedded control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP601BKSZ-REEL7 | 6-lead SC70; adds LE/HYS pin for programmable hysteresis (0.1–160 mV) and latch mode; same 3.5 ns delay. | Required where adaptive hysteresis or sample-and-hold functionality is needed - e.g., variable-threshold ATE fixtures. | Select ADCMP601BKSZ-REEL7 only if hysteresis tuning or latching is mandatory; ADCMP600BKSZ-R2 offers lower cost and smaller footprint when fixed 2 mV suffices. |
| MAX999EXT+T | 3.5 ns delay, 2.7 V to 5.5 V supply, but no rail-to-rail input (−0.2 V to VCC − 1.2 V); higher 5.5 mV offset; no hysteresis. | Suitable for legacy designs where input swing stays above 1.2 V below VCC - not viable for sub-rail sensing or precision low-VOS apps. | Choose MAX999EXT+T only for drop-in replacement in existing MAX999 layouts; ADCMP600BKSZ-R2 provides superior input range, lower offset, and integrated hysteresis. |
Compared with ADCMP601BKSZ-REEL7, ADCMP600BKSZ-R2 trades hysteresis programmability and latch capability for reduced pin count, smaller SC70-5 footprint, and lower system-level EMI from fewer control traces. Against MAX999EXT+T, it delivers wider input range, tighter offset, and built-in noise immunity - making it preferable for new designs demanding rail-to-rail sensing and deterministic timing.

FAQ
What is the maximum input overdrive the ADCMP600BKSZ-R2 can tolerate without damage or phase reversal?
The ADCMP600BKSZ-R2 tolerates differential input voltages up to ±(VCCI + 0.5 V) and common-mode voltages from −0.5 V to VCCI + 0.5 V per Absolute Maximum Ratings. Crucially, its outputs do not phase reverse when inputs exceed the valid common-mode range (−0.2 V to VCC + 0.2 V), preserving signal integrity during transient overdrive events. This behavior is confirmed in the General Description section of the datasheet.
Does the ADCMP600BKSZ-R2 support dual supplies (separate VCCI and VCCO)?
No, the ADCMP600BKSZ-R2 does not support independent input and output supplies. It uses a single shared supply pin (Pin 5, labeled VCCI/VCCO) for both input and output sections. Dual-supply operation with split rails is exclusive to the ADCMP602 variant; ADCMP600BKSZ-R2 is optimized for simplicity in single-rail systems.
Can the hysteresis of the ADCMP600BKSZ-R2 be adjusted externally?
No, the ADCMP600BKSZ-R2 has fixed internal hysteresis of approximately 2 mV and no LE/HYS control pin. Unlike ADCMP601/602, it lacks the ability to adjust hysteresis via external resistor or current source. This fixed value is specified in Table 1 under "Hysteresis (ADCMP600)" and is designed to suppress noise without requiring external components.
What is the minimum load capacitance the ADCMP600BKSZ-R2 output can drive while maintaining 3.5 ns propagation delay?
The ADCMP600BKSZ-R2 is fully characterized for 5 pF load capacitance - the maximum load at which the 3.5 ns propagation delay (at 50 mV overdrive, 2.5 V supply) is guaranteed. Driving larger capacitive loads increases slew-limited delay and may degrade timing dispersion; for >5 pF, a buffer stage is recommended to preserve sub-4 ns performance.
Is the ADCMP600BKSZ-R2 RoHS compliant and lead-free?
Yes, the ADCMP600BKSZ-R2 is RoHS compliant and lead-free. The "-R2" suffix denotes tape-and-reel packaging per JEDEC standard, and the SC70 package construction meets EU RoHS Directive 2011/65/EU requirements. Full compliance documentation, including material declarations, is available through Analog Devices' product page and Aetrix Electronics' quality portal.
