Product details
Overview
ADCMP350YKSZ-REEL7 from Analog Devices is an ultra-low-power, open-drain active-low comparator with integrated 0.6 V reference, designed for voltage detection in space-constrained, high-temperature systems. It operates from 2.25 V to 5.5 V supply, tolerates up to 22 V on VIN and OUT pins, consumes only 10 µA typical supply current, and delivers 5 µs propagation delay across −40°C to +125°C - enabling use in automotive battery monitors and portable equipment.
For engineers reviewing the ADCMP350YKSZ-REEL7 datasheet, ADCMP350YKSZ-REEL7 pinout, ADCMP350YKSZ-REEL7 application, or ADCMP350YKSZ-REEL7 equivalent, key selection criteria include its inverting input configuration, open-drain active-low output stage, 15 mV hysteresis, 10 nA input bias current at 0.6 V, and SC70-4 package compatibility with thermally demanding PCB layouts.
Technical Context
The ADCMP350YKSZ-REEL7 implements a precision inverting comparator topology with an internal 0.6 V reference, where VIN connects to the inverting input and the reference is applied to the noninverting input. Its open-drain output requires an external pull-up resistor and sinks current when VIN exceeds the threshold, asserting logic low.
Designed for robust operation in harsh environments, it supports rail-to-rail input voltage (0–22 V) independent of VCC, maintains stable trip thresholds over temperature (30 ppm/°C), and exhibits low input leakage (≤170 µA at VIN = 22 V, TA = +125°C) - critical for high-impedance sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.25 V to 5.5 V - powers directly from 3.3 V or 5 V rails without regulation. |
| Input Voltage Range | 0 V to 22 V - enables direct monitoring of unregulated battery or bus voltages without attenuation. |
| Reference Voltage | 0.6 V ±21 mV (TA = −40°C to +125°C) - sets precise, factory-trimmed trip point for inverting configuration. |
| Propagation Delay | 5 µs (VIN = VTH to VTH − 100 mV) - ensures timely response in fast-acting fault detection circuits. |
| Supply Current | 10 µA typical - extends battery life in always-on voltage supervision applications. |
| Hysteresis | 15 mV - suppresses noise-induced chatter without requiring external feedback components. |
| Input Bias Current | 10 nA at VIN = 0.6 V - minimizes loading error in high-impedance divider networks. |
Pinout & Package
ADCMP350YKSZ-REEL7 is housed in a 4-lead SC70 (KS-4) package - 2.20 mm × 1.35 mm footprint, 0.95 mm height, lead pitch 0.65 mm - optimized for high-density PCBs and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Inverting Input | Accepts analog input signal; comparator trips when VIN rises above internal 0.6 V reference. |
| 2 - GND | Analog Ground | Reference node for internal circuitry and reference; must be low-impedance connection. |
| 3 - OUT | Open-Drain Active-Low Output | Sinks current when triggered; requires external pull-up to define logic-high level and voltage domain. |
| 4 - VCC | Positive Supply | Provides power for internal reference and comparator; tolerant to 22 V transient on other pins. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3011IDBVR | 0.2 V reference, 1.8–5.5 V supply, 1 µA supply current, SOT-23-5 package. | Lacks 22 V input tolerance; suited for low-voltage, ultra-low-power systems only. | Select when supply is ≤5.5 V and input signals stay within VCC range; not suitable for direct 12 V/24 V bus monitoring. |
| MAX9021AXK+T | 1.235 V reference, 2.5–5.5 V supply, 1.5 µA supply current, SC70-5 package. | Higher reference voltage requires different resistor scaling; no 22 V pin tolerance. | Choose for higher threshold accuracy in 3.3 V systems where external reference trimming is acceptable. |
Compared with TLV3011IDBVR and MAX9021AXK+T, ADCMP350YKSZ-REEL7 uniquely combines 22 V input tolerance, inverting configuration, and factory-trimmed 0.6 V reference in SC70-4 - making it the only option among the three qualified for direct high-voltage battery monitoring in automotive and industrial settings without external protection.

FAQ
What is the function of the VIN pin on the ADCMP350YKSZ-REEL7?
The VIN pin on the ADCMP350YKSZ-REEL7 serves as the inverting input terminal. It accepts the analog signal to be compared against the internal 0.6 V reference applied to the noninverting input. When the voltage at VIN rises above the reference, the open-drain output pulls low. This configuration enables direct high-side voltage monitoring using a simple resistor divider, and the pin tolerates up to 22 V regardless of VCC level - a key feature of the ADCMP350YKSZ-REEL7.
Does the ADCMP350YKSZ-REEL7 require an external pull-up resistor on the OUT pin?
Yes, the ADCMP350YKSZ-REEL7 features an open-drain active-low output, so an external pull-up resistor is mandatory to establish a defined logic-high voltage level. The value depends on rise time requirements and load capacitance, but typical values range from 10 kΩ to 100 kΩ. Without this resistor, the OUT pin remains floating when inactive, making the ADCMP350YKSZ-REEL7 nonfunctional in most digital interface scenarios.
What is the operating temperature range specified for the ADCMP350YKSZ-REEL7?
The ADCMP350YKSZ-REEL7 is fully specified from −40°C to +125°C ambient temperature, with all key parameters - including reference voltage accuracy, propagation delay, and supply current - guaranteed across this range. This extended grade qualifies the ADCMP350YKSZ-REEL7 for under-hood automotive, industrial motor control, and outdoor equipment applications where thermal resilience is critical.
Can the ADCMP350YKSZ-REEL7 be used to monitor voltages above 5.5 V?
Yes, the ADCMP350YKSZ-REEL7 can monitor voltages up to 22 V on the VIN pin, independent of its 2.25 V to 5.5 V supply range. This is achieved through internal high-voltage input structures - no external clamping or attenuation is required for inputs within that range. For example, a 12 V battery can be monitored directly using a 20:1 resistor divider to scale 12 V down to 0.6 V at VIN, preserving accuracy while leveraging the full 22 V tolerance of the ADCMP350YKSZ-REEL7.
How does hysteresis work in the ADCMP350YKSZ-REEL7?
The ADCMP350YKSZ-REEL7 includes fixed 15 mV internal hysteresis to prevent output oscillation caused by noise near the switching threshold. Unlike adjustable hysteresis schemes used in noninverting comparators, this hysteresis is built into the comparator core and requires no external components. It ensures clean, chatter-free transitions when VIN crosses the 0.6 V reference in either direction - a key reliability feature of the ADCMP350YKSZ-REEL7 in electrically noisy environments.
