Product details
Overview
The MAX4452EXK-T from Maxim Integrated is a single-channel, unity-gain stable, rail-to-rail output operational amplifier optimized for low-power, high-speed signal conditioning in portable systems. It delivers 200MHz -3dB bandwidth, 95V/µs slew rate, and 20ns rise/fall times while consuming only 620µA per amplifier from a +2.7V to +5.25V single supply - enabling use in cellular telephone baseband chains and keyless entry receiver front-ends.
For engineers reviewing the MAX4452EXK-T datasheet, MAX4452EXK-T pinout, MAX4452EXK-T application, or MAX4452EXK-T equivalent, this page provides verified electrical specifications, SC70-5 package details, real-world application context for battery-powered RF signal paths, and validated alternative op-amps with documented gain-bandwidth trade-offs.
Technical Context
The MAX4452EXK-T employs a voltage-feedback architecture with internal compensation for unity-gain stability. Its bipolar process enables high slew rate (95V/µs) and wide small-signal bandwidth (200MHz) while maintaining rail-to-rail output swing within 180mV of either supply rail under 1kΩ load.
Input common-mode range extends from (VEE − 0.1V) to (VCC − 1.5V), supporting ground-sensing operation in single-supply configurations. The device exhibits 30MHz 0.1dB gain flatness and low distortion (−83dBc SFDR at 1MHz, VCC = 5V), making it suitable for precision analog front-ends where signal fidelity and power efficiency are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +5.25V - supports direct connection to Li-ion battery or regulated 3.3V/5V rails without level-shifting. |
| Quiescent Current | 620µA per amplifier - enables >100-hour operation in coin-cell–powered instrumentation. |
| -3dB Bandwidth | 200MHz - preserves integrity of IF signals up to 100MHz in zero-IF receivers. |
| Slew Rate | 95V/µs - ensures <20ns full-scale settling for 2V step inputs, critical for pulse-amplifier stages. |
| Rail-to-Rail Output | Swings to within 180mV of VCC/VEE - maximizes dynamic range in 3.3V ADC buffer applications. |
| Input Offset Voltage | 0.4mV typical - minimizes DC error in precision transimpedance or sensor amplification. |
| Gain Flatness | ±0.1dB to 30MHz - maintains amplitude accuracy across multi-carrier LTE/WiFi baseband spectra. |
Pinout & Package
The MAX4452EXK-T is housed in a 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm), optimized for space-constrained portable PCBs. Pin 1 is marked with a dot; the package is lead-free and RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives 1kΩ loads to rail-to-rail voltages; requires isolation resistor for >22pF capacitive loads. |
| 2 | VEE | Negative supply terminal - tied to ground in single-supply operation; must be decoupled with 0.1µF capacitor. |
| 3 | IN+ | Noninverting input - accepts common-mode signals down to ground; input bias current 0.8µA typical. |
| 4 | IN− | Inverting input - forms feedback node in standard configurations; matched to IN+ for offset voltage tracking. |
| 5 | VCC | Positive supply terminal - operates across full 2.7V–5.25V range; PSRR 60dB minimum over frequency. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Internally compensated for AVCL = +1V/V - eliminates need for external compensation in buffer or gain-of-one circuits. |
| Ultra-low power consumption | 620µA supply current - achieves 323MHz/mA speed/power ratio, outperforming legacy rail-to-rail op-amps by >2×. |
| Rail-to-rail output stage | 180mV headroom at 1kΩ load - enables full utilization of 3.3V ADC input range without level-shifting circuitry. |
| High-speed pulse response | 20ns rise/fall time - supports clean amplification of digital control pulses and fast-settling sensor outputs. |
| Low distortion at 1MHz | −83dBc SFDR (VCC = 5V) - preserves SNR in IF sampling and direct-conversion receiver chains. |

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 | Identical electrical specs; packaged in SOT23-5 instead of SC70-5 - 0.1mm larger footprint, 0.2mm higher profile. | Preferred when board assembly uses SOT23-compatible pick-and-place tooling or requires slightly higher thermal dissipation (571mW vs. 247mW). | Select MAX4452EUK-T if mechanical compatibility with existing SOT23 land patterns is required. |
| ADA4891-1ARJZ-R7 | 220MHz bandwidth, 175V/µs slew rate, 800µA supply current - higher speed and power; not unity-gain stable (min gain = +2V/V). | Requires external compensation for unity-gain use; better suited for gain-of-two video line drivers than baseband buffers. | Choose ADA4891-1ARJZ-R7 only when ≥+2V/V closed-loop gain is acceptable and extra 150µA current budget is available. |
Compared with MAX4452EUK-T, the MAX4452EXK-T offers identical performance in a smaller SC70 package ideal for ultra-compact layouts, while the ADA4891-1ARJZ-R7 trades unity-gain stability for higher slew rate and bandwidth - requiring redesign of feedback networks for most MAX4452EXK-T applications.

FAQ
What is the operating temperature range for the MAX4452EXK-T?
The MAX4452EXK-T is specified for operation from −40°C to +85°C. This industrial temperature range ensures reliable performance in automotive keyless entry fobs, handheld test instruments, and cellular handset baseband sections exposed to ambient thermal cycling. All DC and AC parameters in the datasheet are guaranteed across this full range.
Does the MAX4452EXK-T require external compensation for unity-gain operation?
No, the MAX4452EXK-T is internally compensated for unity-gain stability (AVCL = +1V/V). It does not require external compensation components in buffer or gain-of-one configurations. This simplifies design and reduces PCB area versus op-amps requiring external capacitors for stability at low gains.
Can the MAX4452EXK-T drive capacitive loads directly?
The MAX4452EXK-T is not optimized for direct capacitive load driving. For loads exceeding 22pF, an isolation resistor (RISO) must be placed in series with the output to maintain stability and prevent ringing. Figure 1 and Figure 2 in the datasheet provide RISO vs. CLOAD guidance; typical values range from 10Ω to 30Ω depending on load capacitance.
What is the input common-mode voltage range of the MAX4452EXK-T?
The MAX4452EXK-T supports an input common-mode voltage range from (VEE − 0.1V) to (VCC − 1.5V). With VEE = 0V and VCC = 3.3V, this allows inputs from −0.1V to +1.8V - enabling true ground-sensing operation while avoiding phase reversal. Performance degrades outside this range but no latch-up occurs.
How does the MAX4452EXK-T compare to the MAX4352EXK-T in terms of bandwidth and gain stability?
The MAX4452EXK-T offers 200MHz −3dB bandwidth and is unity-gain stable, whereas the MAX4352EXK-T provides 80MHz bandwidth but requires minimum +5V/V closed-loop gain. Both share identical 620µA supply current and SC70-5 packaging. Use MAX4452EXK-T for gain-of-one buffers; choose MAX4352EXK-T only when fixed +5V/V or higher gain is acceptable.
