Product details
Overview
ADCMP604BKSZ-R2 from Analog Devices is a rail-to-rail, single-supply LVDS comparator in a 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 supply, supports −0.2 V to VCCI + 0.2 V input common-mode range, and features a shutdown pin for low-power operation in high-speed instrumentation and clock restoration systems.
For engineers reviewing the ADCMP604BKSZ-R2 datasheet, ADCMP604BKSZ-R2 pinout, ADCMP604BKSZ-R2 application, or ADCMP604BKSZ-R2 equivalent, key selection criteria include propagation delay dispersion (<1.6 ns over 10–125 mV overdrive), LVDS-compatible differential output (245–445 mV swing), input offset voltage (±5 mV), power supply rejection (>60 dB), and −40°C to +125°C operating temperature range.
Technical Context
The ADCMP604BKSZ-R2 uses Analog Devices' proprietary XFCB2 process to achieve sub-ns timing precision with 1 ps rms random jitter. Its dual-front-end input stage enables true rail-to-rail operation across −0.5 V to VCCI + 0.2 V, while robust input overdrive protection prevents phase reversal beyond valid common-mode range.
The LVDS output stage drives standard LVDS inputs directly without external termination, maintaining 1.125–1.375 V common-mode voltage and <50 mV peak-to-peak common-mode noise. A dedicated SDN pin enables fast shutdown (1.4 ns sleep time) and wake-up (25 ns), supporting dynamic power management in burst-mode systems.

Pinout & Package
ADCMP604BKSZ-R2 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 |
|---|---|---|
| Q (Pin 1) | Noninverting LVDS output | Asserts logic high when VP > VN; drives standard LVDS receiver with 245–445 mV differential swing. |
| VEE (Pin 2) | Negative supply reference | Must be connected to system ground or negative rail; EPAD electrically tied to this node. |
| VP (Pin 3) | Noninverting analog input | Accepts signals from −0.5 V to VCCI + 0.2 V; supports rail-to-rail common-mode range. |
| VN (Pin 4) | Inverting analog input | Matches VP in voltage range and bias current; differential pair enables precise threshold comparison. |
| VCCI/VCCO (Pin 5) | Shared input/output supply | Simplifies layout by eliminating separate VCCI/VCCO routing; sets both input stage bias and LVDS driver voltage. |
| Q (Pin 6) | Inverting LVDS output | Complementary to Pin 1; provides full differential signaling for noise immunity and EMI reduction. |
Key Features

FAQ
What is the maximum input overdrive the ADCMP604BKSZ-R2 can handle without performance degradation?
The ADCMP604BKSZ-R2 supports differential input voltages up to ±(VCCI + 0.5 V) per Absolute Maximum Ratings, and its input stage remains linear and non-phase-reversing up to VCCI + 0.2 V common-mode voltage. Propagation delay dispersion stays below 1.6 ns for overdrives from 10 mV to 125 mV, confirming stable timing behavior across this range. The device's robust front-end design tolerates large transient overdrives without latch-up or parameter shift, making ADCMP604BKSZ-R2 suitable for pulse spectroscopy and ATE environments with unpredictable signal excursions.
Does the ADCMP604BKSZ-R2 require external termination resistors for LVDS output drive?
No, the ADCMP604BKSZ-R2 does not require external termination resistors for LVDS output drive. Its internal LVDS output stage is designed to directly drive standard 100 Ω differential LVDS inputs, delivering 245–445 mV differential swing and maintaining 1.125–1.375 V common-mode voltage. The datasheet specifies performance with RLOAD = 100 Ω, confirming that the output impedance and drive strength are matched to the LVDS standard. Adding external termination would mismatch the output network and degrade signal integrity, so ADCMP604BKSZ-R2 should be connected directly to the LVDS receiver's 100 Ω differential input.
Can the ADCMP604BKSZ-R2 operate with VCCI and VCCO supplied from different voltage rails?
No, the ADCMP604BKSZ-R2 cannot operate with separate VCCI and VCCO rails because it uses a single shared supply pin (Pin 5) for both input and output sections. Unlike the ADCMP605, which has dedicated VCCI and VCCO pins, ADCMP604BKSZ-R2 integrates these functions onto one terminal. Attempting to apply different voltages risks damaging the device due to internal connection between input and output supply domains. For split-supply operation, the ADCMP605BCPZ-R2 is the appropriate variant; ADCMP604BKSZ-R2 is optimized for simplified single-supply designs where VCCI = VCCO.
What is the function of the VEE pin on the ADCMP604BKSZ-R2, and must it be connected to ground?
The VEE pin (Pin 2) on ADCMP604BKSZ-R2 serves as the negative supply reference and substrate connection point. It must be connected to the system ground or lowest potential rail in the application. The exposed pad (EPAD) is electrically tied to VEE, and the datasheet explicitly states "IF CONNECTED, THE EPAD MUST BE CONNECTED TO VEE." Leaving VEE floating violates Absolute Maximum Ratings and risks latch-up or parametric shift. In single-supply configurations, VEE = GND establishes the reference for rail-to-rail input operation and ensures proper biasing of the internal differential pair. Therefore, reliable operation of ADCMP604BKSZ-R2 requires a solid, low-impedance connection from Pin 2 to system ground.
How does the shutdown feature of the ADCMP604BKSZ-R2 affect propagation delay and output state?
When the shutdown pin (SDN) of ADCMP604BKSZ-R2 is driven low, the device enters low-power mode with ICCI reduced to 0.92–1.1 mA. During shutdown, the LVDS outputs go to a high-impedance (Hi-Z) state - neither Q nor Q asserts a defined logic level. Wake-up time is 25 ns (from SDN high to valid output), and sleep time is 1.4 ns (from SDN low to output invalid). Propagation delay is undefined during shutdown, as the internal amplifier stages are disabled. This behavior allows ADCMP604BKSZ-R2 to be rapidly gated in burst-mode systems without affecting downstream timing; however, outputs must be externally terminated or buffered if Hi-Z state is incompatible with receiving logic.
