Product details
Overview
ADCMP601BKSZ-REEL7 from Analog Devices is a rail-to-rail, single-supply high-speed comparator with 3.5 ns propagation delay at 2.5 V, 10 mW power consumption, −0.2 V to VCC + 0.2 V input common-mode range, and programmable hysteresis/latch via LE/HYS pin. It operates from 2.5 V to 5.5 V and supports applications including clock/data restoration and high-speed threshold detection.
For engineers reviewing the ADCMP601BKSZ-REEL7 datasheet, ADCMP601BKSZ-REEL7 pinout, ADCMP601BKSZ-REEL7 application, or ADCMP601BKSZ-REEL7 equivalent, this page delivers verified electrical specs, SC70-6 package mapping, latch timing behavior, hysteresis control design meaning, and real-world use cases in pulse spectroscopy and ATE systems.
Technical Context
The ADCMP601BKSZ-REEL7 uses Analog Devices' XFCB2 process for high-speed operation with matched rising/falling propagation delays (≤500 ps skew) and low overdrive dispersion (<1.2 ns from 10–125 mV). Its dual-front-end input stage features crossover bias points at ~0.8 V and ~1.6 V, enabling robust rail-to-rail operation across −40°C to +125°C.
It integrates a TTL/CMOS-compatible output stage rated for ≤5 pF load with full timing compliance, plus a single-pin LE/HYS terminal that simultaneously enables latch mode (low-active) and programmable hysteresis (via resistor or current source), eliminating external feedback networks and associated parasitics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.5 ns at VCC = 2.5 V, 50 mV overdrive - enables sub-300 MHz signal sampling with deterministic timing. |
| Input Common-Mode Range | −0.2 V to VCC + 0.2 V - supports ground-referenced and beyond-rail inputs without clamping diodes. |
| Supply Voltage Range | 2.5 V to 5.5 V single supply - interoperable with 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Power Dissipation | 10 mW at 3.3 V - balances speed and thermal efficiency for compact PCB layouts. |
| Hysteresis Control | Programmable 0.1–160 mV via LE/HYS pin - replaces external resistive feedback with stable, predictable hysteresis tuning. |
| Output Drive | TTL/CMOS-compatible, drives ≥1 Schottky TTL or 3 LSTTL loads - interfaces directly to FPGA I/O banks and microcontroller GPIOs. |
| PSRR | >50 dB - maintains timing accuracy despite supply ripple in noisy industrial or ATE environments. |
Pinout & Package
ADCMP601BKSZ-REEL7 is housed in a 6-lead SC70 package (JEDEC MO-203AA), footprint-compatible with SOT-23 but with reduced thermal resistance (θJA = 426°C/W) and optimized for high-frequency layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Q | Noninverting Output | CMOS/TTL logic-level output; active-high when VP > VN in compare mode; latched state held during LE/HYS low. |
| 2 - GND | Negative Supply Reference | Low-inductance return path for both input and output sections; must be connected to solid ground plane. |
| 3 - VP | Noninverting Analog Input | Rail-to-rail input capable of −0.2 V to VCC + 0.2 V; differential pair node with ±2 mV offset and 1 pF capacitance. |
| 4 - VN | Inverting Analog Input | Complementary differential input; matched to VP for <200 ps common-mode dispersion and <500 ps skew. |
| 5 - LE/HYS | Latch Enable / Hysteresis Control | Single terminal supporting two modes: drive low for latch (tPL = 21 ns min), bias with resistor for hysteresis (0.1–160 mV). |
| 6 - VCCI/VCCO | Shared Input/Output Supply | Single-pin supply for both analog input stage and digital output driver; simplifies routing in single-supply systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with dual-front-end architecture | Enables accurate threshold detection at GND and VCC rails without signal attenuation or phase reversal. |
| Programmable hysteresis via LE/HYS pin | Eliminates need for external positive feedback resistors, reducing component count and layout sensitivity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX999EUK+T | 5 ns propagation delay, no latch/hysteresis control pin, fixed 2 mV hysteresis only, SC70-5 package. | Lacks LE/HYS functionality; unsuitable for applications requiring dynamic hysteresis adjustment or synchronous latching. | Select MAX999EUK+T only when latch-free, lower-cost comparison is sufficient and board space allows SC70-5 footprint. |
| TLV3501DBVR | 4.5 ns delay, rail-to-rail input, no latch pin, 3.3 V max supply, SOT-23-5 package. | Lower supply voltage ceiling and missing latch/hysteresis control limit use in wide-VCC or synchronized sampling systems. | Choose TLV3501DBVR for cost-sensitive 3.3 V-only designs where latch and programmable hysteresis are not required. |
Compared with MAX999EUK+T and TLV3501DBVR, ADCMP601BKSZ-REEL7 uniquely combines sub-4 ns delay, single-pin latch/hysteresis control, and 2.5–5.5 V operation-making it the only option for compact, flexible, high-speed thresholding with synchronous capture capability.

FAQ
What is the maximum input overdrive the ADCMP601BKSZ-REEL7 can handle without damage?
The ADCMP601BKSZ-REEL7 supports differential input voltages up to ±(VCCI + 0.5 V) and absolute input voltages from −0.5 V to VCCI + 0.5 V per Absolute Maximum Ratings. Within these limits, the device exhibits no phase reversal and maintains robust operation-even with large overdrive-due to its protected input stage. Always observe the 50 mA maximum input/output current rating.
How does the LE/HYS pin function in latch mode versus hysteresis mode?
In latch mode, driving the LE/HYS pin low (≤0.4 V) captures and holds the comparator output state until the next low pulse; setup/hold times are 2 ns and 2.6 ns respectively. In hysteresis mode, biasing the pin with a resistor to GND sets hysteresis from 0.1 mV to 160 mV-no conflict exists between modes, and both can coexist using open-drain drivers. The ADCMP601BKSZ-REEL7 implements this dual functionality on a single terminal without external components.
Does ADCMP601BKSZ-REEL7 require separate input and output supplies?
No-ADCMP601BKSZ-REEL7 uses a shared VCCI/VCCO supply pin, simplifying single-supply designs. Unlike the ADCMP602 (which separates VCCI and VCCO), the ADCMP601BKSZ-REEL7 integrates both sections onto one rail, operating reliably from 2.5 V to 5.5 V. This eliminates sequencing concerns and reduces bypass capacitor count while retaining full 3.5 ns propagation delay performance.
What is the typical hysteresis value when the LE/HYS pin is left floating?
When the LE/HYS pin is left unconnected (floating), the ADCMP601BKSZ-REEL7 defaults to a fixed hysteresis of approximately 2 mV-matching the ADCMP600's internal hysteresis. This value is stable across temperature and supply voltage, providing noise immunity for basic threshold detection without external components. For adjustable hysteresis, a resistor to GND must be added per Figure 10 and Figure 21 in the datasheet.
Can ADCMP601BKSZ-REEL7 drive a 50 Ω transmission line directly?
No-ADCMP601BKSZ-REEL7 is specified for ≤5 pF capacitive loads and is not designed for direct 50 Ω line driving. Attempting to drive a 50 Ω load causes excessive current draw, output distortion, and timing degradation. For transmission line interfacing, use a dedicated buffer (e.g., AD8001 or SN65LVDS1) after the ADCMP601BKSZ-REEL7 to preserve signal integrity and meet rise/fall time specs.
