Product details
Overview
MAX4352EUK-T from Maxim Integrated is a single, high-speed, rail-to-rail output operational amplifier optimized for minimum closed-loop gain of +5V/V, delivering 80MHz -3dB bandwidth, 240V/µs slew rate, and ultra-low 620µA supply current per amplifier. It operates from a single +2.7V to +5.25V supply and targets battery-powered RF signal conditioning in keyless entry transceivers and cellular baseband stages.
For engineers reviewing the MAX4352EUK-T datasheet, MAX4352EUK-T pinout, MAX4352EUK-T application, or MAX4352EUK-T equivalent, this page provides verified electrical specifications, SOT23-5 package layout, real-world use cases in low-voltage wideband analog front-ends, and validated alternative op-amps with documented gain-bandwidth trade-offs.
Technical Context
The MAX4352EUK-T uses a voltage-feedback architecture with internal compensation for stable operation at AVCL ≥ +5V/V. Its bipolar process enables fast large-signal response (8ns rise/fall time) and low distortion (–74dBc 2nd-harmonic at 1MHz, VOUT = 2Vp-p, VCC = 5V), while maintaining rail-to-rail output swing within 180mV of either supply rail under 1kΩ load.
It features ground-sensing input common-mode range (VEE – 0.1V to VCC – 1.5V), 30MΩ input resistance, and 15nV/√Hz input voltage noise density at 10kHz - enabling precision DC-coupled gain stages without external level-shifting circuitry in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 80MHz at AVCL = +5V/V - supports baseband video and IF signal amplification up to 40MHz Nyquist frequency. |
| Slew Rate | 240V/µs - ensures faithful reproduction of fast transient signals such as digital burst envelopes or pulse-modulated RF carriers. |
| Supply Current | 620µA per amplifier - enables >100-hour battery life in coin-cell-powered sensor nodes with active analog signal chain. |
| Input Voltage Noise | 15nV/√Hz at 10kHz - preserves SNR in low-amplitude sensor interfaces like piezoelectric microphone preamps. |
| Output Swing | Rail-to-rail, within 180mV of VCC/VEE at 1kΩ - maximizes dynamic range in 3.3V ADC driver applications. |
| Common-Mode Rejection | 60–100dB over DC–10MHz - suppresses power-supply ripple and coupled noise in noisy embedded environments. |
| Operating Supply | +2.7V to +5.25V single supply - eliminates need for dual-rail generation in portable instrumentation. |
Pinout & Package
The MAX4352EUK-T is housed in a 5-pin SOT23-5 package (JEDEC MO-178), with 1.3mm × 2.9mm footprint and 1.0mm height - compatible with standard pick-and-place equipment and space-constrained PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal; rail-to-rail capable, drives 1kΩ load to within 180mV of supply rails. |
| 2 | VEE | Negative power supply pin (typically GND in single-supply configurations); must be bypassed with 0.1µF capacitor. |
| 3 | IN+ | Noninverting input; supports common-mode range down to VEE – 0.1V for true ground-referenced sensing. |
| 4 | IN− | Inverting input; matched to IN+ for <±1mV offset voltage matching in dual/quad variants (not applicable to single MAX4352). |
| 5 | VCC | Positive power supply pin (+2.7V to +5.25V); requires local 0.1µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Gain-stable at AVCL ≥ +5V/V | Eliminates external compensation components in fixed-gain instrumentation amplifier stages. |
| 240V/µs slew rate | Supports clean amplification of 50MHz square waves without edge rounding or overshoot. |
| Rail-to-rail output | Delivers full 3.3Vpp output swing from 3.3V supply - avoids headroom loss in ADC buffer designs. |
| 620µA quiescent current | Enables always-on analog monitoring in ultra-low-power IoT endpoints without thermal derating. |
| 15nV/√Hz input noise | Maintains >70dB SNR for 100mVpp sensor signals digitized by 12-bit ADCs sampling at 10Msps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4452EUK-T | Unity-gain stable; 200MHz bandwidth, 95V/µs slew rate, same 620µA supply current. | Requires redesign of feedback network for AVCL = +1V/V; unsuitable for fixed +5V/V gain without external compensation. | Select when unity-gain buffering or variable-gain configurations are needed; avoid if fixed +5V/V gain is mandatory. |
| LMV793MMX/NOPB | Single 220MHz GBW op-amp; 1.1mA supply current; rail-to-rail output; only 110V/µs slew rate. | Higher power consumption limits battery runtime; lower slew rate may distort fast edges in digital burst applications. | Choose for higher DC precision (0.25mV VOS) where speed is secondary; not recommended for >10MHz pulse integrity. |
Compared with MAX4352EUK-T, MAX4452EUK-T offers higher bandwidth but requires different gain configuration, while LMV793MMX/NOPB trades 78% higher supply current for marginally better DC accuracy - making MAX4352EUK-T optimal for fixed-gain, battery-sensitive wideband signal paths.

FAQ
What is the minimum stable closed-loop gain for MAX4352EUK-T?
The MAX4352EUK-T is internally compensated for stable operation at closed-loop gains of +5V/V or greater. Attempting unity-gain or gains below +5V/V may cause peaking or oscillation due to insufficient phase margin. For AVCL < +5V/V, external compensation or selection of the unity-gain stable MAX4452EUK-T is required. This gain constraint is explicitly specified in the datasheet AC Electrical Characteristics table.
Does MAX4352EUK-T support rail-to-rail input operation?
No, the MAX4352EUK-T does not support rail-to-rail input. Its input common-mode voltage range is specified from (VEE – 0.1V) to (VCC – 1.5V). At VCC = 3.3V, this means the input cannot exceed 1.8V - limiting true ground-referenced differential sensing. However, its rail-to-rail output delivers full swing from VEE to VCC, making it ideal for driving ADCs or logic interfaces directly.
What is the maximum capacitive load the MAX4352EUK-T can drive without instability?
The MAX4352EUK-T is not optimized for highly reactive loads. Driving >22pF directly risks reduced phase margin and ringing. The datasheet recommends using an isolation resistor (RISO) between the output and capacitive load - with RISO = 18Ω for 50pF, 22Ω for 100pF, and up to 30Ω for 150pF - to restore stability. Layout best practices also require minimizing parasitic capacitance at the output node.
Can MAX4352EUK-T operate from a 2.5V supply?
No, the absolute minimum supply voltage for MAX4352EUK-T is +2.7V as specified in the Absolute Maximum Ratings and DC Electrical Characteristics tables. Operation at 2.5V falls outside guaranteed specifications and may result in degraded bandwidth, increased input offset voltage, or failure to meet rail-to-rail output swing requirements. Systems requiring 2.5V operation should consider alternatives like the MAX4478 or ADA4891-1.
Is MAX4352EUK-T pin-compatible with other devices in the MAX4452/MAX4352 family?
Yes, the MAX4352EUK-T shares identical pinout and package (SOT23-5) with the MAX4452EUK-T, MAX4352EXK-T, and MAX4452EXK-T. All four variants use the same OUT/VEE/IN+/IN−/VCC pin mapping on the SOT23-5 body. This allows direct substitution in existing layouts when switching between unity-gain and minimum +5V/V gain variants - provided the application's gain requirement aligns with the selected device.
