Product details
Overview
CMP402GRU-REEL from Analog Devices is a quad low-voltage comparator with 65 ns propagation delay, separate analog (±5 V or 0 V/5 V) and digital (3 V or 5 V) supplies, and wide input common-mode range (–5 V to +4.0 V). It operates across –40°C to +125°C and targets portable instrumentation interfaces requiring rail-to-rail input capability and logic-level output compatibility.
For engineers reviewing the CMP402GRU-REEL datasheet, CMP402GRU-REEL pinout, CMP402GRU-REEL application, or CMP402GRU-REEL equivalent, key selection criteria include propagation delay vs. overdrive, dual-supply isolation, analog supply current (1.2–2.0 mA), output drive strength (3.2 mA), and TSSOP-16 thermal resistance (180°C/W).
Technical Context
The CMP402GRU-REEL implements four independent high-speed comparators with fully isolated analog and digital supply domains: analog section supports ±5 V, 0 V/+5 V, or 0 V/–5 V configurations; digital section accepts 3 V or 5 V logic-compatible supplies. Input stage features ±8 V differential voltage rating and –5 V to +4.0 V common-mode range, enabling direct interface with bipolar sensor outputs or legacy industrial signals.
Its 65 ns typical propagation delay (100 mV step, 20 mV overdrive, TA = 25°C) is optimized for read channel detection and level translation where timing margin exceeds that of the faster CMP401 variant. Output stage delivers VOH ≥ 2.6 V (IOH = –3.2 mA) and VOL ≤ 0.25 V (IOL = 3.2 mA) into 10 kΩ loads under 3 V digital supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 65 ns typical (100 mV input step, 20 mV overdrive, VANA = ±5 V, VDIG = 3 V, TA = 25°C) - defines maximum signal decision latency in high-speed threshold detection |
| Analog Supply Current | 1.2–2.0 mA (TA = –40°C to +125°C) - enables battery-operated designs with <2 mA per comparator analog section |
| Digital Supply Current | 1.0–2.25 mA (VO = 0 V, RL = ∞) - ensures low-power 3 V/5 V logic interfacing without external level shifters |
| Input Common-Mode Range | –5.0 V to +4.0 V - supports direct connection to ±5 V op-amp outputs or unipolar 0–4 V sensors without attenuation |
| Output Drive Capability | ±3.2 mA (VOH/VOL tested at 3.2 mA sink/source) - drives standard TTL/CMOS inputs and small capacitive loads (≤15 pF) directly |
| Offset Voltage | 4.5 mV max (TA = 25°C) - sets minimum detectable differential voltage without external trimming |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and downhole instrumentation environments |
Pinout & Package
Package: 16-lead TSSOP (RU-16), 4.4 mm × 5.0 mm body, 0.65 mm pitch, JEDEC MO-153 compliant. Thermal resistance: θJA = 180°C/W, θJC = 37°C/W.

| 9 | V– ANA | Analog negative supply pin; connects to ground or –5 V reference for bipolar operation |
| 10 | DIG GND | Digital ground return; must be separated from analog ground to maintain PSRR >60 dB |
| 11, 12, 14, 15 | OUT A, OUT B, OUT C, OUT D | Open-collector compatible CMOS outputs; require external pull-up to V+DIG (3 V or 5 V) |

Key Features
| Feature | Design Value |

Applications
| Battery-Powered Sensor Interface | Industrial Level Translator |
|---|---|
|
Use Scenario: Monitoring thermocouple or strain gauge outputs in handheld test equipment powered by two AA cells (3 V nominal). IC Role / Device Role / Timing Role: Quad comparator performs simultaneous zero-crossing and threshold detection on four analog channels before ADC sampling. Use Value: 1.2 mA analog supply current extends battery life; –5 V to +4.0 V input range accepts raw sensor amplifier outputs without scaling. |
Use Scenario: Converting ±10 V industrial control signals to 3.3 V logic levels for FPGA input in programmable logic controllers. IC Role / Device Role / Timing Role: Acts as precision level translator with hysteresis to reject noise on long cable runs between field devices and controller backplane. Use Value: 65 ns delay ensures deterministic response to fast transients; separate V+ANA/V+DIG prevents digital switching noise from corrupting analog reference stability. |
| Read Channel Detection | Line Receiver for Legacy Bus |
|
Use Scenario: Detecting magnetic head transitions in optical disk drive servo systems using analog waveform peak detection. IC Role / Device Role / Timing Role: One comparator channel triggers on rising edge of differentiated read signal; others monitor bias and error conditions. Use Value: 65 ns propagation delay provides sufficient timing margin for 10 Mbps channel data rates while maintaining jitter below 1% UI. |
Use Scenario: Receiving RS-422 or differential LVDS-like signals in aerospace avionics where EMI immunity is critical. IC Role / Device Role / Timing Role: Comparator converts differential input to single-ended CMOS logic for downstream timing recovery circuits. Use Value: ±8 V differential input range accommodates degraded signal amplitudes after long cable runs; 60 dB CMRR rejects common-mode noise up to 100 kHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Slower (1.3 µs propagation delay), no separate analog/digital supplies, wider offset voltage (7 mV max), SOIC-14 package | Not suitable for high-speed read channels or mixed-supply systems; requires external level shifting for ±5 V inputs | Select LM339DR only for cost-sensitive, low-frequency (<100 kHz) threshold detection where power and speed are secondary. |
| TLV3201DBVR | Faster (40 ns), single 2.7–5.5 V supply, rail-to-rail input, SOT-23-6 (single-channel), no bipolar input support | Lacks quad configuration and ±5 V input capability; unsuitable for multi-channel analog monitoring with bipolar sources | Choose TLV3201DBVR for ultra-low-power, single-channel 3 V systems but not as drop-in replacement for CMP402GRU-REEL's quad/bipolar functionality. |
Compared with LM339DR and TLV3201DBVR, the CMP402GRU-REEL uniquely combines quad channel count, 65 ns speed, ±5 V input tolerance, and true dual-supply isolation-making it irreplaceable in portable instrumentation requiring simultaneous multi-signal conditioning with minimal external components.

FAQ
What is the maximum allowable analog supply voltage for CMP402GRU-REEL?
The absolute maximum total analog supply voltage for CMP402GRU-REEL is 16 V, with individual limits of ±6 V on V+ANA and V–ANA. Operation at ±5 V is specified in all electrical characteristics tables and supports full performance across –40°C to +125°C. Exceeding ±6 V risks permanent damage per the ABSOLUTE MAXIMUM RATINGS table on page 4 of the datasheet.
Does CMP402GRU-REEL support rail-to-rail input operation?
Yes, CMP402GRU-REEL supports rail-to-rail input operation relative to its analog supply rails: input common-mode voltage range extends from V–ANA (–5 V) to V+ANA – 1.0 V (+4.0 V when V+ANA = +5 V). This allows direct interface with op-amps and sensors operating at either supply rail, unlike many comparators limited to V–ANA + 1.5 V minimum.
Can CMP402GRU-REEL operate with only a single 3.3 V supply?
No - CMP402GRU-REEL requires two independent supplies: one for the analog section (V+ANA and V–ANA) and one for the digital output section (V+DIG and DIG GND). A single 3.3 V rail cannot simultaneously satisfy both domains; V+DIG may be 3.3 V, but V+ANA/V–ANA must be configured separately (e.g., 0 V/+3.3 V or ±3.3 V) per the functional block diagram and pin configuration.
What is the output configuration of CMP402GRU-REEL?
CMP402GRU-REEL features open-drain (open-collector compatible) CMOS outputs. Each of the four outputs (OUT A–D) requires an external pull-up resistor to V+DIG (3 V or 5 V). The datasheet specifies VOH ≥ 2.6 V at IOH = –3.2 mA and VOL ≤ 0.25 V at IOL = 3.2 mA, confirming active-pull-down capability with logic-level high defined by the external pull-up.
Is CMP402GRU-REEL pin-compatible with CMP401GRU-REEL?
Yes - CMP402GRU-REEL and CMP401GRU-REEL share identical TSSOP-16 pinouts, package dimensions, and footprint. They differ only in propagation delay (65 ns vs. 23 ns), analog supply current (1.2–2.0 mA vs. 6–8 mA), and input common-mode range (–5 V to +4.0 V vs. –5 V to +3.9 V), allowing direct substitution where speed and power trade-offs are acceptable.
