Product details
Overview
ADCMP603BCPZ-R7 from Analog Devices is a rail-to-rail, single-supply comparator with 3.5 ns propagation delay at 2.5 V, ±2 mV offset voltage, and complementary TTL/CMOS outputs - designed for high-speed threshold detection in clock restoration and pulse spectroscopy systems.
For engineers reviewing the ADCMP603BCPZ-R7 datasheet, ADCMP603BCPZ-R7 pinout, ADCMP603BCPZ-R7 application, or ADCMP603BCPZ-R7 equivalent, key selection considerations include programmable hysteresis via LE/HYS pin, shutdown functionality, dual supply independence (VCCI/VCCO), and guaranteed operation from −40°C to +125°C in LFCSP-12 packaging.
Technical Context
The ADCMP603BCPZ-R7 employs a proprietary XFCB2 process and features dual independent supply rails (VCCI for input stage, VCCO for output stage), enabling flexible signal swing control and power optimization. Its input common-mode range extends from −0.2 V to VCC + 0.2 V, supporting rail-to-rail operation across 2.5 V to 5.5 V supplies.
It integrates a unique single-pin LE/HYS terminal that supports both latch mode activation and precise hysteresis programming (0.1 mV to ~160 mV) via external resistor or current source, while maintaining full timing integrity and low glitch behavior in CMOS/TTL-compatible outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 3.5 ns at VCCI = VCCO = 2.5 V, 50 mV overdrive - enables sub-300 MHz timing-critical decision circuits. |
| Input Offset Voltage | ±2 mV typical - ensures accurate threshold detection with minimal calibration overhead. |
| Supply Range | VCCI and VCCO independently rated 2.5 V to 5.5 V - allows split-supply operation without sequencing constraints. |
| Output Drive | Complementary TTL/CMOS outputs driving up to 5 pF load - delivers clean, low-skew transitions without external buffering. |
| Hysteresis Control | Programmable 0.1–160 mV via LE/HYS pin bias - eliminates need for external feedback resistors and preserves bandwidth. |
| Shutdown Current | 290–430 µA at 2.5 V - reduces system standby power while retaining fast 50 ns wake-up time. |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood, industrial PLC, and aerospace sensor interface use. |
Pinout & Package
ADCMP603BCPZ-R7 is housed in a 3 mm × 3 mm, 12-lead Lead Frame Chip Scale Package (LFCSP-CP-12-5) with exposed pad electrically tied to VEE. Thermal resistance θJA = 62°C/W in still air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCCO) | Output section supply | Independent power rail for output drivers - decouples switching noise from input stage and enables logic-level matching. |
| 2 (VCCI) | Input section supply | Separate supply for analog front-end - supports wide input common-mode range and improves PSRR. |
| 3, 5, 9, 11 (VEE) | Negative supply reference | Multiple ground-return paths reduce impedance and improve high-frequency stability; exposed pad connects here. |
| 4 (VP) | Noninverting analog input | Rail-to-rail capable (−0.2 V to VCCI + 0.2 V); differential input capacitance = 1.0 pF minimizes loading on high-Z sources. |
| 6 (VN) | Inverting analog input | Matched to VP in offset, bias current, and capacitance - critical for low dispersion in precision timing applications. |
| 7 (SDN) | Shutdown control | Active-low enable; <20 ns sleep entry and 50 ns wake-up ensure minimal latency in power-gated systems. |
| 8 (LE/HYS) | Latch/hysteresis control | Single pin supports either edge-triggered latching (driven low) or precision hysteresis programming (biased at ~1.25 V). |
| 10 (Q) | Inverting CMOS/TTL output | True complement of Q; VOH = VCCO − 0.4 V, VOL = 0.4 V at 8 mA - compatible with 2.5 V/3.3 V/5 V logic families. |
| 12 (Q) | Noninverting CMOS/TTL output | Drives high when VP > VN; matched skew (<300 ps Q-to-Q) preserves timing integrity in differential signaling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with common-mode range from −0.2 V to VCCI + 0.2 V - supports direct interfacing to sensors, DACs, and AC-coupled signals without level-shifting. |
| Programmable hysteresis | Adjustable 0.1–160 mV via external resistor on LE/HYS pin - replaces discrete feedback networks and avoids parasitic-induced instability. |
| Independent input/output supplies | VCCI and VCCO can differ by ±3.0 V during operation - enables mixed-voltage systems (e.g., 2.5 V input sensing, 5 V logic interfacing) without level translators. |
| Low-glitch output stage | Complementary CMOS/TTL drivers with <500 ps skew and graceful capacitive degradation - maintains timing accuracy even with 10–15 pF board traces. |
| Robust ESD protection | 4.5 kV HBM rating and absolute max ratings including ±50 mA pin current limits - enhances reliability in automated test and field-deployed instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADCMP600BRJZ-REEL7 | Slower 5.5 ns propagation delay; no programmable hysteresis or latch function; SOT-23-6 package. | Limited to basic threshold detection where timing margin > 2 ns is acceptable and board space is constrained. | Select when cost sensitivity outweighs speed/hysteresis requirements and PCB layout cannot accommodate LFCSP-12. |
| TLV3501IDBVR | 3.5 ns delay but only 2.7 V to 5.5 V supply range; no independent VCCI/VCCO; no shutdown pin; SOT-23-6. | Suitable for battery-powered portable instruments but lacks rail-to-rail input below 0 V and thermal robustness beyond +85°C. | Choose only for consumer-grade designs requiring lowest BOM cost and operating strictly within commercial temperature range. |
Compared with ADCMP603BCPZ-R7, ADCMP600BRJZ-REEL7 trades speed and configurability for compactness and cost, while TLV3501IDBVR sacrifices supply flexibility, temperature range, and feature set to meet entry-level price targets - neither offers the same combination of 125°C operation, programmable hysteresis, and dual-supply independence.

FAQ
What is the minimum input overdrive required for specified propagation delay in ADCMP603BCPZ-R7?
The ADCMP603BCPZ-R7 achieves its 3.5 ns typical propagation delay at 50 mV overdrive with VCCI = VCCO = 2.5 V. At 10 mV overdrive, delay increases to 5 ns. The device maintains functional operation down to 5 mV overdrive, but timing-critical designs should target ≥50 mV to guarantee spec-compliant performance per the datasheet's Table 1 and Figure 10.
Can ADCMP603BCPZ-R7 operate with VCCI = 2.5 V and VCCO = 5.5 V simultaneously?
Yes, ADCMP603BCPZ-R7 supports independent input and output supplies with VCCI − VCCO ranging from −3.0 V to +3.0 V during operation. This allows configurations such as 2.5 V analog sensing (VCCI) driving 5 V logic (VCCO), provided each supply is properly bypassed to ground and no supply exceeds its absolute maximum rating of −0.5 V to +6.0 V.
How is hysteresis programmed on ADCMP603BCPZ-R7 using the LE/HYS pin?
Hysteresis on ADCMP603BCPZ-R7 is programmed by connecting an external resistor from the LE/HYS pin (Pin 8) to GND. A 65–95 kΩ resistor yields ~120 mV hysteresis; values from open-circuit (0 mV) to ~10 kΩ (~160 mV) are supported. The pin presents a 1.25 V bias through ~7 kΩ series resistance - no external voltage source is needed, and bias current is internally sourced.
Does ADCMP603BCPZ-R7 require external pull-up resistors on its Q and Q outputs?
No, ADCMP603BCPZ-R7 features active push-pull CMOS/TTL-compatible outputs with VOH = VCCO − 0.4 V and VOL = 0.4 V at 8 mA drive strength. Pull-ups are unnecessary and discouraged - adding them degrades rise/fall times, increases power, and may cause contention if VCCO differs from the target logic rail.
What is the thermal performance of ADCMP603BCPZ-R7 in its LFCSP package?
The ADCMP603BCPZ-R7 in 12-lead LFCSP (CP-12-5) has a junction-to-ambient thermal resistance θJA of 62°C/W under standard JEDEC test conditions (still air). With proper PCB layout - including soldering the exposed pad to a thermal plane - actual θJA can be reduced by 20–30%, supporting continuous 30 mW dissipation at +125°C ambient without derating.
