Product details
Overview
CMP402GRUZ-REEL from Analog Devices is a quad low-voltage comparator with separate analog and digital supply domains, 65 ns propagation delay (typ), ±5 V analog input common-mode range, and 1.4 mA analog supply current at 25°C. It operates across –40°C to +125°C and targets portable instrumentation interfaces requiring level translation between bipolar analog signals and 3 V/5 V logic.
For engineers reviewing the CMP402GRUZ-REEL datasheet, CMP402GRUZ-REEL pinout, CMP402GRUZ-REEL application, or CMP402GRUZ-REEL equivalent, key selection factors include dual-supply isolation, wide analog input voltage range (–5 V to +4.0 V), fast response under low power, and TSSOP-16 packaging for space-constrained industrial sensing designs.
Technical Context
The CMP402GRUZ-REEL implements four independent comparators with fully isolated analog and digital sections: analog supplies support ±5 V operation (V+ANA/V–ANA), while digital supplies accept 3 V or 5 V (V+DIG/DIG GND). This architecture enables direct interfacing of negative-rail analog signals to positive-only logic without level-shifting circuitry.
Its 65 ns propagation delay (100 mV step, 20 mV overdrive) is achieved with only 1.4 mA analog and 2.0 mA digital supply current at 25°C, maintaining stable performance across –40°C to +125°C. Input offset voltage is 4.5 mV max, and common-mode rejection is 60 dB over 0.1 V to 1.9 V.
Key Specifications

| 9 | V– ANA | Analog negative supply rail - enables true bipolar analog input operation down to –5 V |
| 10 | DIG GND | Digital ground reference - isolated from analog ground to prevent noise coupling |
| 11, 12, 14, 15 | OUT A, OUT B, OUT C, OUT D | Open-collector compatible CMOS outputs - drive 3 V/5 V logic directly when pulled up externally |
| 13 | V+ DIG | Digital positive supply - sets output logic high level (3 V or 5 V) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Single 5 V supply only; no analog/digital separation; 1.3 µs propagation delay; wider offset (7 mV max) | Requires external level shifting for bipolar inputs; unsuitable for high-speed read channels or noise-sensitive mixed-signal systems | Select when cost is primary constraint and system uses only 5 V rails with slow thresholds |
| TLV3704IPW | Single 2.7–16 V supply; rail-to-rail inputs; 2.5 µs delay; 1.5 mV offset; 85 µA supply current | Lower power but much slower; lacks bipolar input capability; not rated beyond 85°C | Select for ultra-low-power battery devices where speed <100 kHz and temperature ≤85°C |
Compared with LM339DR and TLV3704IPW, the CMP402GRUZ-REEL uniquely delivers bipolar analog input handling, sub-100 ns speed, and extended temperature operation - making it irreplaceable in automotive sensor interfaces and industrial data acquisition where supply domain isolation and timing integrity are non-negotiable.

FAQ
What is the maximum analog input voltage range supported by the CMP402GRUZ-REEL?
The CMP402GRUZ-REEL supports an analog input common-mode voltage range of –5.0 V to +4.0 V when operated with ±5 V analog supplies. This allows direct connection to bipolar sensors, op-amp outputs, and legacy industrial transducers without external level-shifting circuitry. The absolute maximum input voltage is ±7 V, as specified in the Absolute Maximum Ratings table.
Does the CMP402GRUZ-REEL require separate analog and digital ground planes?
Yes - the CMP402GRUZ-REEL has physically isolated analog (V+ANA, V–ANA) and digital (V+DIG, DIG GND) supply domains. To preserve noise immunity and ensure specified performance, Analog Devices recommends separating analog and digital ground planes and connecting them at a single point near the device. Mixing grounds compromises common-mode rejection and increases propagation delay variation.
Can the CMP402GRUZ-REEL operate with a 3 V digital supply and ±5 V analog supplies simultaneously?
Yes - the CMP402GRUZ-REEL is explicitly designed for mixed-supply operation. It supports V+DIG = 3 V (or 5 V) while V+ANA = +5 V and V–ANA = –5 V. This configuration enables clean 3 V logic interfacing to ±5 V analog signal chains, as confirmed in the General Description and Electrical Specifications sections of the REV. B datasheet.
What is the typical propagation delay of the CMP402GRUZ-REEL under standard test conditions?
The typical propagation delay of the CMP402GRUZ-REEL is 65 ns, measured with a 100 mV input step and 20 mV overdrive at TA = 25°C, V+ANA = V+DIG = 5.0 V, and VCM = 0.1 V. This value is confirmed in the "DYNAMIC PERFORMANCE" section of the REV. B datasheet and remains stable across –40°C to +125°C within published limits.
Is the CMP402GRUZ-REEL pin-compatible with the CMP401GRUZ-REEL?
Yes - the CMP402GRUZ-REEL and CMP401GRUZ-REEL share identical pinouts, package (TSSOP-16), and supply domain assignments. They differ only in propagation delay (65 ns vs. 23 ns) and analog supply current (1.4 mA vs. 6.5 mA). This allows direct functional substitution where speed requirements permit, without PCB layout changes.
