Product details
Overview
ADCMP604BKSZ-REEL7 from Analog Devices is a rail-to-rail, single-supply LVDS comparator in 6-lead SC70 package, delivering 1.6 ns propagation delay, 600 ps rise/fall time, and 37 mW power dissipation at 2.5 V. It operates from 2.5 V to 5.5 V input supply, supports −0.2 V to VCCI + 0.2 V common-mode input range, and features shutdown control for low-power operation in high-speed instrumentation and clock restoration.
For engineers reviewing the ADCMP604BKSZ-REEL7 datasheet, ADCMP604BKSZ-REEL7 pinout, ADCMP604BKSZ-REEL7 application, or ADCMP604BKSZ-REEL7 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative comparators with documented functional distinctions.
Technical Context
The ADCMP604BKSZ-REEL7 uses a proprietary XFCB2 process to achieve 1.6 ns propagation delay with ≤70 ps output skew and <1.6 ns overdrive dispersion across 10–125 mV input overdrive. Its dual-front-end input stage enables rail-to-rail operation from −0.2 V to VCCI + 0.2 V while maintaining <5 mV offset voltage and >60 dB PSRR.
It integrates an LVDS-compatible differential output stage driving 100 Ω loads with 245–445 mV differential swing and 1.125–1.375 V common-mode level, plus a dedicated SDN pin enabling 1.4 ns sleep entry and 25 ns wake-up-critical for burst-mode timing systems requiring deterministic latency control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.6 ns typical at 50 mV overdrive - enables sub-2 ns timing resolution in pulse-width modulators and ATE trigger circuits. |
| Input Common-Mode Range | −0.2 V to VCCI + 0.2 V - supports direct interfacing with ±0.2 V referenced sensors or DAC outputs without level-shifting. |
| Supply Voltage Range | 2.5 V to 5.5 V - allows operation from single Li-ion battery (3.3 V) up to industrial 5 V rails without external regulators. |
| LVDS Output Swing | 245–445 mV differential into 100 Ω - meets ANSI/TIA/EIA-644-A LVDS standard for noise-immune inter-board signaling. |
| Power Dissipation | 37 mW at 2.5 V - enables dense placement in thermal-constrained FPGA timing modules without forced air cooling. |
| Shutdown Current | 0.92–1.1 mA - reduces standby power by >95% vs active mode, supporting energy-efficient duty-cycled measurement systems. |
| Input Offset Voltage | ±5.0 mV - ensures accurate threshold detection down to 10 mV signal margins in peak/zero-crossing detectors. |
Pinout & Package
ADCMP604BKSZ-REEL7 is housed in a 6-lead SC70 (KS-6) package with exposed pad connected to VEE. Thermal resistance θJA = 426°C/W in still air. Pin 1 is Q (noninverting output), Pin 2 is VEE (negative supply), Pin 3 is VP (noninverting input), Pin 4 is VN (inverting input), Pin 5 is VCCI/VCCO (shared input/output supply), and Pin 6 is Q (inverting output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q) | Noninverting LVDS Output | Drives LVDS receiver inputs directly; logic high when VP > VN; requires 100 Ω termination to VCCI/2 for proper common-mode bias. |
| 2 (VEE) | Negative Supply Reference | Must be connected to system ground or negative rail; EPAD electrically tied to VEE for thermal conduction and noise immunity. |
| 3 (VP) | Noninverting Analog Input | Accepts signals from −0.2 V to VCCI + 0.2 V; internal ESD protection prevents phase reversal beyond valid range. |
| 4 (VN) | Inverting Analog Input | Matches VP in bandwidth and offset; differential pair rejects common-mode noise up to 50 dB CMRR. |
| 5 (VCCI/VCCO) | Shared Input/Output Supply | Single-pin 2.5–5.5 V supply powers both input stage and LVDS driver; bypass with 0.01 µF capacitor near pin. |
| 6 (Q) | Inverting LVDS Output | Complementary to Pin 1; enables differential signaling for jitter reduction and EMI suppression in clock distribution paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with inputs as low as −0.2 V and as high as VCCI + 0.2 V - eliminates need for external clamping diodes in wide-dynamic-range sensor interfaces. |
| LVDS-compatible output | Delivers 245–445 mV differential swing into 100 Ω load - interoperable with standard LVDS receivers without level translators or resistive dividers. |
| Programmable shutdown | SDN pin enables 1.4 ns sleep entry and 25 ns wake-up - supports microsecond-scale power gating in time-of-flight or pulsed laser systems. |
| Low propagation delay dispersion | <1.6 ns variation across 10–125 mV overdrive - preserves timing fidelity in multi-channel ATE where input amplitudes vary between DUTs. |
| High PSRR (>60 dB) | Maintains stable switching thresholds despite supply ripple - critical for clock recovery in noisy switch-mode power supply environments. |
Applications
| High-Speed Clock Restoration | Threshold Detection in Pulse Spectroscopy |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP605BCPZ-REEL7 | 12-lead LFCSP with separate VCCI/VCCO pins, LE/HYS pin for hysteresis/latch, no shared supply pin | Supports split-supply operation and programmable hysteresis - suited for systems requiring adjustable decision thresholds or latch functionality | Select ADCMP605BCPZ-REEL7 when hysteresis control or independent input/output supplies are needed; not pin-compatible with ADCMP604BKSZ-REEL7. |
| TLV3501DBVR | 6-lead SOT-23, 4.5 ns propagation delay, CMOS output, no LVDS driver, 2.7–5.5 V supply | Lacks LVDS output and rail-to-rail input - requires external level-shifting for differential signaling and cannot accept sub-ground inputs | Choose TLV3501DBVR only for cost-sensitive, lower-speed (<200 MHz) applications where LVDS compliance and extended input range are unnecessary. |
Compared with ADCMP604BKSZ-REEL7, ADCMP605BCPZ-REEL7 adds hysteresis control and split-supply capability at the cost of larger footprint and non-interchangeable pinout, while TLV3501DBVR trades speed, interface compatibility, and input range for lower unit cost and simpler layout in non-LVDS systems.

FAQ
What is the maximum input frequency the ADCMP604BKSZ-REEL7 can reliably process?
The ADCMP604BKSZ-REEL7 has a specified input bandwidth of 500 MHz and supports minimum input pulse widths of 1.3 ns. It maintains stable operation with input slew rates up to 10 V/ns and delivers consistent 1.6 ns propagation delay across overdrive ranges from 10 mV to 125 mV - making it suitable for signals up to 500 MHz in well-bypassed, low-inductance layouts.
Does the ADCMP604BKSZ-REEL7 support true rail-to-rail input operation down to ground or below?
Yes, the ADCMP604BKSZ-REEL7 supports input voltages from −0.2 V to VCCI + 0.2 V across its full 2.5 V to 5.5 V supply range. This includes operation 0.2 V below ground (VEE), enabling direct interfacing with bipolar sensor outputs or DACs that swing below GND without external level-shifting circuitry.
Can the ADCMP604BKSZ-REEL7 be used with separate input and output supplies?
No - the ADCMP604BKSZ-REEL7 uses a single shared VCCI/VCCO pin (Pin 5) for both input and output sections. For split-supply operation with independent VCCI and VCCO, the pin-compatible ADCMP605BCPZ-REEL7 (12-lead LFCSP) must be used instead, as it provides dedicated VCCI and VCCO pins plus LE/HYS functionality.
What is the purpose of the exposed pad on the ADCMP604BKSZ-REEL7 SC70 package?
The exposed pad on the ADCMP604BKSZ-REEL7 is electrically connected to VEE (Pin 2) and serves as a thermal and electrical reference plane. It must be soldered to a PCB copper pour tied to system ground or negative supply to achieve rated θJA = 426°C/W and reduce high-frequency noise coupling into the sensitive input stage.
How does the shutdown feature affect timing performance of the ADCMP604BKSZ-REEL7?
When the SDN pin is driven low, the ADCMP604BKSZ-REEL7 enters shutdown mode with 0.92–1.1 mA supply current, 1.4 ns sleep entry time, and 25 ns wake-up time to full output validity. During wake-up, propagation delay remains stable at 1.6 ns - ensuring deterministic latency recovery for burst-mode applications like time-of-flight sensing or gated oscilloscope front-ends.
