Product details
Overview
CMP401GRUZ-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 rail-to-rail output swing under 3 V/5 V logic-compatible operation - deployed in battery-powered instrumentation for high-speed level translation and read channel detection.
For engineers reviewing the CMP401GRUZ-REEL datasheet, CMP401GRUZ-REEL pinout, CMP401GRUZ-REEL application, or CMP401GRUZ-REEL equivalent, this page delivers verified electrical specs, TSSOP-16 package details, temperature-stable performance across –40°C to +125°C, and direct alternatives for portable interface design where dual-supply flexibility and sub-30 ns response are critical.
Technical Context
The CMP401GRUZ-REEL implements four independent comparators with fully isolated analog and digital supply rails (V+ANA/V–ANA and V+DIG/DIG GND), enabling analog inputs to operate from –5 V to +3.9 V while outputs swing cleanly between 0 V and 3 V or 5 V. Its architecture supports single-supply analog operation down to +3 V or bipolar ±5 V configurations without level-shifting circuitry.
Propagation delay is specified at 23 ns (typ) for 100 mV overdrive with 20 mV overdrive margin, stable across –40°C to +125°C, and exhibits <5 µV/°C offset drift. Input hysteresis is 2 mV (typ), CMRR is 60 dB over 0.1 V to 3.9 V common-mode range, and PSRR is 60 dB for both analog and digital supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 23 ns typical at 100 mV step with 20 mV overdrive - enables real-time signal edge detection in high-speed read channels. |
| Input Common-Mode Range | –5.0 V to +3.9 V - supports direct interfacing to bipolar sensor outputs or legacy industrial signals without external biasing. |
| Supply Configuration | Separate V+ANA/V–ANA and V+DIG/DIG GND - allows analog section to run at ±5 V while digital output drives 3 V logic, eliminating level translators. |
| Offset Voltage | 3 mV max at 25°C - ensures accurate threshold detection in precision battery monitoring and line receiver applications. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-range portable equipment. |
| Output Drive | VOH = 4.6 V min at IOH = –3.2 mA; VOL = 0.2 V max at IOL = 3.2 mA - provides robust TTL/CMOS-compatible switching into 10 kΩ loads. |
| Power Consumption | IANA = 6.5 mA typ, IDIG = 2.0 mA typ at 25°C - balances speed and efficiency for always-on portable instrumentation. |
Pinout & Package
Package: 16-lead TSSOP (RU-16), RoHS-compliant, 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, JEDEC MO-153-AB compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | +IN A, –IN A, +IN B, –IN B | Noninverting/inverting inputs for Comparator A and B - differential pairs accept wide common-mode range including negative voltages. |
| 5, 6, 7, 8 | +IN C, –IN D, +IN D, –IN C | Inputs for Comparators C and D - pin-swapped layout supports differential signaling with matched trace routing. |
| 9, 10 | V– ANA, DIG GND | Analog ground reference and digital ground - kept separate to prevent noise coupling between analog sensing and digital output switching. |
| 11, 12 | V+ DIG, V+ ANA | Digital supply (3 V or 5 V) and analog supply (±3 V to ±6 V) - independent rails enable mixed-voltage system integration. |
| 13–16 | OUT A, OUT B, OUT C, OUT D | Open-collector compatible outputs - each sinks ≥3.2 mA and sources ≤3.2 mA, compatible with pull-up to V+DIG or external logic rails. |
Key Features
| Feature | Design Value |
|---|---|
| 23 ns propagation delay | Enables sub-50 MHz signal edge detection in read channel and timing-critical line receiver circuits. |
| Separate analog/digital supplies | Eliminates need for level shifters when interfacing ±5 V sensors to 3 V microcontrollers or FPGAs. |
| –5 V to +3.9 V input common-mode range | Supports direct connection to unbuffered transducer outputs, battery stack monitors, and legacy RS-422 receivers. |
| –40°C to +125°C operating range | Validated for automotive cabin modules, industrial PLC I/O, and ruggedized handheld test equipment. |
| Low power at high speed | 8.5 mA total supply current (IANA + IDIG) delivers 23 ns response - 3× faster than comparable low-power comparators at same current. |
Applications

| Level Translators | Read Channel Detection |
|
Use Scenario: Converting ±5 V DAC outputs to 3.3 V logic levels for FPGA configuration or ADC trigger generation. IC Role / Device Role / Timing Role: Each comparator acts as a rail-to-rail level shifter with programmable hysteresis to suppress noise-induced glitches. Use Value: Independent V+ANA/V+DIG rails allow analog side to track DAC output while digital side drives 3.3 V I/O - no external level-shifting IC required. |
Use Scenario: Hard disk drive read channel detecting pulse edges from magnetic head preamplifier outputs. IC Role / Device Role / Timing Role: High-speed comparator bank digitizes analog waveform peaks and zero crossings for PRML decoding.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339MTX/NOPB | 300 ns propagation delay, single 5 V supply only, no separate analog/digital rails, 2 mV offset (max). | Lower speed, no bipolar input support - suitable for cost-sensitive industrial controls but not for battery-powered high-speed detection. | Select when budget constraints outweigh timing and supply flexibility requirements; requires external level shifting for ±5 V inputs. |
| TLV3201DBVR | 40 ns propagation delay, 1.8 V to 5.5 V single supply, rail-to-rail input, 1.5 mV offset (max), SOT-23-5 single-channel. | Single-channel, lower power (35 µA), no dual-supply capability - used in space-constrained low-voltage systems but lacks quad integration. | Choose for ultra-low-power, single-comparator functions in wearables or IoT nodes; not drop-in for quad-channel or bipolar-signal use cases. |
Compared with LM339MTX/NOPB and TLV3201DBVR, the CMP401GRUZ-REEL uniquely combines quad integration, 23 ns speed, ±5 V input capability, and true dual-supply independence - making it irreplaceable in portable instrumentation requiring simultaneous high-speed analog decision-making across multiple signal paths without layout or BOM complexity.

FAQ
What is the maximum allowable analog supply voltage for the CMP401GRUZ-REEL?
The absolute maximum total analog supply voltage (V+ANA to V–ANA) is 16 V. Operating specifications are guaranteed for analog supplies from ±3 V to ±6 V. Exceeding ±6 V may cause permanent damage or parametric shift. The CMP401GRUZ-REEL must never be operated with V+ANA – V–ANA > 16 V, and differential input voltage must remain within ±9 V per ABSOLUTE MAXIMUM RATINGS.
Does the CMP401GRUZ-REEL support true bipolar analog inputs?
Yes. The CMP401GRUZ-REEL supports analog input common-mode voltages from –5.0 V to +3.9 V when V+ANA = +5 V and V–ANA = 0 V, or from –5.0 V to +4.0 V when V+ANA = +5 V and V–ANA = –5 V. This enables direct connection to bipolar transducers, op amp outputs, and legacy industrial signals without external bias networks - a key feature confirmed in the GENERAL DESCRIPTION and ELECTRICAL SPECIFICATIONS tables.
What is the guaranteed propagation delay for the CMP401GRUZ-REEL over temperature?
The propagation delay for the CMP401GRUZ-REEL is guaranteed to be ≤30 ns over the full –40°C to +125°C operating range, with 23 ns typical at 25°C for 100 mV input step and 20 mV overdrive. TPC 5 and TPC 3 in the datasheet confirm delay remains below 30 ns across temperature, making it suitable for timing-critical applications in automotive and industrial environments.
Can the digital and analog grounds be tied together in a PCB layout using the CMP401GRUZ-REEL?
No - DIG GND (Pin 10) and V–ANA (Pin 9) must be kept as separate ground planes or traces and joined only at a single point near the device or at the system power supply return. Mixing them directly introduces digital switching noise into the analog reference, degrading offset, CMRR, and propagation delay consistency. The functional block diagram and PIN CONFIGURATIONS explicitly show these as distinct terminals for noise isolation.
Is the CMP401GRUZ-REEL pin-compatible with the CMP402GRUZ-REEL?
Yes - both the CMP401GRUZ-REEL and CMP402GRUZ-REEL share identical 16-lead TSSOP (RU-16) pinouts, pin functions, and package dimensions. However, they differ electrically: the CMP401GRUZ-REEL delivers 23 ns propagation delay and higher analog supply current (6.5 mA typ), while the CMP402GRUZ-REEL offers 65 ns delay and lower analog current (1.4 mA typ). Swapping requires validation of timing and power budgets.
