Product details
Overview
CMP401GS-REEL from Analog Devices is a quad low-voltage comparator with separate analog and digital supply domains, 23 ns propagation delay (typ), ±5 V to +3.9 V input common-mode range, and operation over –40°C to +125°C - used in battery-powered instrumentation for level translation between mixed-supply subsystems.
For engineers reviewing the CMP401GS-REEL datasheet, CMP401GS-REEL pinout, CMP401GS-REEL application, or CMP401GS-REEL equivalent, this page delivers verified electrical specs, SOIC-16 pin mapping, real-world use cases in portable sensing and read-channel detection, and two validated alternative comparators with documented functional trade-offs.
Technical Context
The CMP401GS-REEL integrates four independent high-speed comparators with fully isolated analog and digital supply rails (V+ANA/V–ANA and V+DIG/DIG GND), enabling interface between ±5 V analog front-ends and 3 V/5 V logic domains without level-shifting circuitry. Its input stage supports differential inputs up to ±8 V and common-mode voltages from –5 V to +4.0 V.
Propagation delay is specified at 23 ns (typ) for 100 mV input step with 20 mV overdrive under V+ANA = V+DIG = 5 V, –VANA = 0 V to –5 V, and RL = 10 kΩ. Output stage drives TTL/CMOS loads with VOH ≥ 4.6 V (IOH = –3.2 mA) and VOL ≤ 0.2 V (IOL = 3.2 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 23 ns typical - enables sub-44 MHz noninverting switching (20 MHz @ ±100 mV input) |
| Input Common-Mode Range | –5.0 V to +4.0 V - supports direct connection to bipolar sensor outputs or op-amp stages |
| Supply Separation | V+ANA/V–ANA and V+DIG/DIG GND - eliminates need for external level translators in mixed-supply systems |
| Offset Voltage | 3 mV max at 25°C - ensures reliable detection of small signal thresholds without trimming |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-range portable equipment |
| Analog Supply Current | 6.5 mA typ at 25°C - balances speed and power for always-on battery-operated monitoring nodes |
| Digital Supply Current | 2.0 mA typ at 25°C - compatible with low-power microcontroller I/O domains |
Pinout & Package
Package: 16-lead narrow SOIC (R-16A), surface-mount, JEDEC MS-012 compliant, 10.0 mm × 4.0 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | +IN A/B/C/D | Noninverting inputs for each of four comparator channels |
| 2, 4, 6, 8 | –IN A/B/C/D | Inverting inputs for each channel; support differential or single-ended configurations |
| 9 | V– ANA | Analog ground or negative analog supply rail (supports –5 V operation) |
| 10 | DIG GND | Digital ground reference - must be connected separately from V– ANA unless system shares ground |
| 11, 12, 14, 15 | OUT A/B/C/D | Open-collector compatible CMOS/TTL outputs - require external pull-up to V+DIG |
| 13 | V+ DIG | Digital supply rail (3 V or 5 V) - powers output stage and defines logic-high level |
| 16 | V+ ANA | Analog positive supply (2.7 V to 6 V or ±3 V to ±6 V) - sets input dynamic range and biasing |
Key Features

| Extended temperature range (–40°C to +125°C) | Validated for deployment in automotive engine control modules and industrial motor drives |
| Low power per channel (≤2.25 mA digital + 8.0 mA analog) | Reduces thermal load in compact, sealed enclosures with limited airflow |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339MTX/NOPB | Slower (1.3 µs delay), single-supply only (2–36 V), no separate digital/analog rails | Lacks rail separation - requires external level-shifting for mixed-supply interfaces | Choose when cost sensitivity outweighs speed and supply flexibility; not suitable for CMP401GS-REEL's dual-rail architecture |
| MAX961ESA+ | Faster (4.5 ns), single 2.7–5.5 V supply, rail-to-rail inputs, but only dual-channel | Higher speed but no negative analog input capability; unsuitable for bipolar sensor interfaces | Consider only for 3 V-only, high-frequency applications where –5 V input support is unnecessary |
Compared with LM339MTX/NOPB and MAX961ESA+, the CMP401GS-REEL uniquely combines 23 ns speed, ±5 V analog input compatibility, and true supply-domain isolation - making it irreplaceable in portable instrumentation requiring robust mixed-voltage signal conditioning.

FAQ
What is the maximum allowable analog supply voltage for the CMP401GS-REEL?
The absolute maximum total analog supply voltage (V+ANA – V–ANA) for the CMP401GS-REEL is 16 V. Operating within recommended conditions, V+ANA may range from 2.7 V to 6 V (or ±3 V to ±6 V), with V–ANA typically at 0 V or –5 V. Exceeding 16 V risks permanent damage per the device's Absolute Maximum Ratings table.
Does the CMP401GS-REEL support true bipolar input operation?
Yes, the CMP401GS-REEL supports true bipolar input operation: its input common-mode voltage range extends from –5.0 V to +4.0 V, and differential input voltage tolerance is ±8.0 V. This allows direct connection to op-amps biased with negative supplies or legacy industrial transducers outputting below ground.
Can the CMP401GS-REEL operate with 3 V digital and 5 V analog supplies simultaneously?
Yes - the CMP401GS-REEL is explicitly designed for independent supply domains. V+DIG may be set to 3 V while V+ANA operates at 5 V (and V–ANA at 0 V or –5 V), enabling seamless interfacing between low-voltage logic and higher-voltage analog signal chains without level-shifting components.
What is the guaranteed propagation delay specification for the CMP401GS-REEL over temperature?
The CMP401GS-REEL guarantees a maximum propagation delay of 30 ns over the full –40°C to +125°C operating range when tested with a 100 mV input step and 20 mV overdrive. At 25°C, typical delay is 23 ns, with worst-case 33 ns observed at low overdrive (5 mV).
Is the CMP401GS-REEL pin-compatible with the CMP402GS-REEL?
No - while both share identical SOIC-16 pinouts and package footprints, the CMP401GS-REEL and CMP402GS-REEL differ in internal design: the CMP401 offers 23 ns delay and higher analog supply current (6.5 mA), whereas the CMP402 provides 65 ns delay and lower quiescent current (1.4 mA). They are functionally substitutable only where speed/power trade-offs are acceptable.
