Product details
Overview
CMP401GSZ-REEL from Analog Devices is a quad low-voltage comparator with 23 ns propagation delay, separate analog (±5 V or +3 V to +6 V) and digital (3 V or 5 V) supply rails, and input common-mode range from –5 V to +3.9 V. It operates over –40°C to +125°C and targets portable instrumentation interfaces requiring fast level translation between bipolar analog and single-supply logic domains.
For engineers reviewing the CMP401GSZ-REEL datasheet, CMP401GSZ-REEL pinout, CMP401GSZ-REEL application, or CMP401GSZ-REEL equivalent, key selection criteria include propagation delay vs. overdrive, dual-supply isolation, input voltage range compatibility with ±5 V analog sources, and SOIC narrow-body thermal performance at extended temperature.
Technical Context
The CMP401GSZ-REEL integrates four independent comparators with fully isolated analog and digital sections: analog inputs accept –5 V to +3.9 V common-mode signals while operating from ±5 V or +3 V to +6 V supplies, and outputs swing rail-to-rail under 3 V or 5 V digital supply control. This architecture enables direct interfacing between legacy bipolar sensor front-ends and modern low-voltage microcontrollers.
Its 23 ns typical propagation delay (100 mV step, 20 mV overdrive, TA = 25°C) is achieved without sacrificing input offset voltage (3–4 mV max), hysteresis (2 mV), or CMRR (60 dB over –4.9 V to +3.9 V). The device maintains stable operation across full industrial temperature range with analog supply current ≤8.0 mA and digital supply current ≤2.25 mA at 5 V.
Key Specifications

Pinout & Package
Package: 16-lead narrow SOIC (SOIC_N, R-16, body width 3.9 mm), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | +IN A/B/C/D | Non-inverting inputs for each of four comparators; accept full –5 V to +3.9 V common-mode range. |
| 2, 4, 6, 8 | –IN A/B/C/D | Inverting inputs; support differential sensing and hysteresis configuration via external feedback. |
| 9 | V– ANA | Analog ground or negative analog supply rail; must be connected to system analog reference for proper input stage bias. |

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), single 5 V supply only, no negative input capability. | Limited to unipolar 0–5 V inputs; unsuitable for ±5 V sensor interfaces or low-latency read channels. | Select LM339DR only for cost-sensitive, low-speed industrial controls where input range and speed are not critical. |
| TLV3201DBVR | Faster (40 ns), single 2.7–5.5 V supply, input range limited to 0.2 V below V– to 0.2 V above V+, no negative rail support. | Requires external level-shifting for bipolar inputs; lacks analog/digital supply separation for noise isolation. | Choose TLV3201DBVR for ultra-low-power portable devices with strictly unipolar signal chains and <100 ns timing budgets. |
Compared with LM339DR and TLV3201DBVR, the CMP401GSZ-REEL uniquely delivers 23 ns speed with true ±5 V input capability and galvanically isolated supply domains-enabling robust, component-count-optimized interfaces in mixed-voltage instrumentation where noise immunity and bipolar signal integrity are mandatory.

FAQ
What is the maximum input differential voltage the CMP401GSZ-REEL can tolerate?
The CMP401GSZ-REEL supports a maximum differential input voltage of ±8.0 V under ±5 V analog supply conditions. This rating ensures safe operation when comparing signals with large amplitude swings-such as ±5 V op-amp outputs-without internal clamp diode conduction or damage. Always observe absolute maximum ratings: differential input voltage must not exceed ±9 V, and input voltage must stay within ±7 V or the analog supply voltage, whichever is less.
Does the CMP401GSZ-REEL require external pull-up resistors on its outputs?
Yes, the CMP401GSZ-REEL features open-collector outputs and requires external pull-up resistors to V+ DIG (3 V or 5 V) to establish valid logic-high levels. Typical values range from 1 kΩ to 10 kΩ depending on rise time and load capacitance requirements. The device sinks up to 3.2 mA with VOL ≤ 0.2 V, making it compatible with standard TTL and CMOS logic families when properly terminated.
Can the CMP401GSZ-REEL operate with only a single positive analog supply (e.g., +5 V and GND)?
Yes-the CMP401GSZ-REEL supports single-ended analog supplies such as +5 V and GND (where V– ANA = GND). In this configuration, the input common-mode range is 0 V to +3.9 V, and the device retains full 23 ns propagation delay performance. This mode is commonly used in 3.3 V/5 V systems where the analog front-end is referenced to ground and does not require negative voltage handling.
What is the recommended PCB layout practice for minimizing noise coupling in the CMP401GSZ-REEL?
To minimize noise coupling, maintain strict separation between analog and digital ground planes, connect them at a single point near the device, and route V+ ANA and V+ DIG with dedicated low-inductance traces. Place 0.1 µF ceramic decoupling capacitors as close as possible to pins 9 (V– ANA), 10 (DIG GND), 12 (V+ DIG), and 15 (V+ ANA). Avoid routing high-speed digital traces beneath the IC body, and use guard rings around sensitive input pins (+IN/–IN) tied to analog ground.
Is the CMP401GSZ-REEL pin-compatible with the CMP402GSZ-REEL?
No-the CMP401GSZ-REEL and CMP402GSZ-REEL share identical pinouts and package footprints (16-lead SOIC), but they are not functionally interchangeable due to significant performance differences: the CMP401GSZ-REEL delivers 23 ns propagation delay, while the CMP402GSZ-REEL is rated for 65 ns. Substituting one for the other may violate timing budgets in high-speed applications; always verify propagation delay, supply current, and input offset specifications before replacement.
