Product details
Overview
ADCMP354YKSZ-REEL7 from Analog Devices is a precision voltage comparator with integrated 0.6 V reference, noninverting input configuration, and open-drain active-high output. It operates from 2.25 V to 5.5 V supply, draws only 10 µA quiescent current, features 15 mV hysteresis, and delivers 5 µs propagation delay across −40°C to +125°C - enabling robust voltage detection in automotive battery monitors.
For engineers reviewing the ADCMP354YKSZ-REEL7 datasheet, ADCMP354YKSZ-REEL7 pinout, ADCMP354YKSZ-REEL7 application, or ADCMP354YKSZ-REEL7 equivalent, key selection criteria include its noninverting topology, 22 V input/output voltage tolerance, SC70-4 package footprint, low-leakage input (10 nA at VIN = 0.6 V), and compatibility with high-voltage rail monitoring without external level-shifting.
Technical Context
The ADCMP354YKSZ-REEL7 implements a noninverting comparator architecture with an internal 0.6 V reference, where VIN connects directly to the noninverting input. Its open-drain output requires an external pull-up resistor and sinks up to 1.2 mA while maintaining ≤0.4 V low-level output voltage at that load.
Designed for high-voltage resilience, it supports up to 22 V on VIN and OUT pins independent of VCC, and exhibits stable threshold accuracy (±21 mV over temperature) and low temperature coefficient (30 ppm/°C) - critical for reliable trip-point behavior in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.25 V to 5.5 V - compatible with 3.3 V and 5 V logic rails without regulation |
| Input Threshold Voltage | 0.6 V ±21 mV (−40°C to +125°C) - fixed internal reference eliminates external resistor divider |
| Propagation Delay | 5 µs (VIN = VTH to VTH − 100 mV) - enables fast response in supply fault detection |
| Quiescent Current | 10 µA typical - supports ultra-low-power operation in battery-backed systems |
| Input Bias Current | 10 nA at VIN = 0.6 V - minimizes loading error on high-impedance voltage dividers |
| Hysteresis | 15 mV typical - suppresses noise-induced oscillation without external feedback components |
| VIN/VOUT Voltage Tolerance | Up to 22 V - allows direct monitoring of 12 V/24 V automotive rails without attenuation |
Pinout & Package
ADCMP354YKSZ-REEL7 uses a 4-lead SC70 (KS-4) package: 2.0 mm × 1.25 mm footprint, 0.65 mm lead pitch, and thin profile (0.9 mm max height). Pin 1 = VIN, Pin 2 = GND, Pin 3 = OUT, Pin 4 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Noninverting Input | Accepts analog input up to 22 V; referenced internally to 0.6 V threshold |
| GND (Pin 2) | Analog Ground | Reference node for internal circuitry and output stage; must be low-impedance |
| OUT (Pin 3) | Open-Drain Output | Active-high logic when pulled up externally; sinks ≥1.2 mA with <0.4 V drop |
| VCC (Pin 4) | Positive Supply | Powers internal reference and comparator; range 2.25 V–5.5 V, independent of VIN/OUT voltage |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 0.6 V Reference | Eliminates need for external reference IC or resistor divider, reducing BOM count and layout area |
| 22 V Input/Output Tolerance | Enables direct connection to unregulated 12 V/24 V automotive or industrial rails without clamping or scaling |
| 10 µA Quiescent Current | Extends battery life in portable equipment and enables always-on monitoring in low-power wake-up circuits |
| 15 mV Internal Hysteresis | Prevents chatter on noisy or slowly ramping signals without requiring external positive feedback resistors |
| −40°C to +125°C Operation | Validated performance across full automotive AEC-Q100 temperature range without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3011IDBVR | 0.2 V internal reference; 1.8 V to 5.5 V supply; push-pull output; no hysteresis | Lacks built-in hysteresis and 22 V tolerance; requires external hysteresis network for noise immunity | Choose TLV3011IDBVR only if lower reference voltage and push-pull output are required, and high-voltage monitoring is not needed. |
| MAX9022AESA+ | 1.235 V reference; 2.7 V to 5.5 V supply; open-drain output; 2 mV hysteresis | Higher reference voltage necessitates different resistor scaling; lower hysteresis may require external feedback in noisy environments | Choose MAX9022AESA+ when higher trip thresholds are preferred and tighter reference accuracy (±0.5%) is prioritized over wide input voltage range. |
Compared with TLV3011IDBVR and MAX9022AESA+, ADCMP354YKSZ-REEL7 uniquely combines 0.6 V reference, 22 V input tolerance, and 15 mV hysteresis in SC70-4 - making it optimal for compact, high-voltage, low-power voltage detection where minimal external components are critical.

FAQ
What is the reference voltage accuracy of ADCMP354YKSZ-REEL7 over temperature?
The ADCMP354YKSZ-REEL7 features a 0.6 V internal reference with ±21 mV total variation across −40°C to +125°C (±3.5% of 0.6 V). At 25°C, the typical threshold is 0.6 V with ±21 mV min/max limits over the full temperature range, and the temperature coefficient is specified at 30 ppm/°C - ensuring predictable drift behavior in thermal cycling applications.
Can ADCMP354YKSZ-REEL7 monitor a 12 V automotive battery directly?
Yes, ADCMP354YKSZ-REEL7 can monitor a 12 V automotive battery directly on its VIN pin because it supports input voltages up to 22 V - well above 12 V nominal and 14.5 V alternator charging peaks. No external attenuation or clamping is required, though a resistor divider is needed to scale the battery voltage down to match the 0.6 V reference threshold.
What is the maximum sink current capability of the ADCMP354YKSZ-REEL7 output?
The ADCMP354YKSZ-REEL7 open-drain output can sink up to 1.2 mA while maintaining an output low voltage ≤0.4 V (at TA = −40°C to +125°C). This allows direct driving of LEDs, optocouplers, or logic inputs with appropriate pull-up resistors - for example, a 4.7 kΩ pull-up to 5 V yields ~1 mA sink current with <0.4 V dropout.
Does ADCMP354YKSZ-REEL7 require external hysteresis components?
No, ADCMP354YKSZ-REEL7 includes 15 mV of internal hysteresis, which is sufficient to suppress noise-induced oscillation in most voltage detection applications. External hysteresis is optional and only recommended when higher hysteresis (e.g., >30 mV) is required for extremely noisy environments or slow-ramping signals.
What package type and dimensions does ADCMP354YKSZ-REEL7 use?
ADCMP354YKSZ-REEL7 uses the SC70-4 (KS-4) package: 2.0 mm × 1.25 mm body size, 0.65 mm lead pitch, and 0.9 mm maximum height. It is RoHS-compliant (Z suffix), tape-and-reel packaged (REEL7), and pin-compatible with other ADCMP35x variants in the same family - simplifying design reuse across threshold polarity and output topology variants.
