Product details
Overview
MAX4353ESA from Maxim Integrated is a dual, high-speed, voltage-feedback operational amplifier compensated for minimum +5V/V closed-loop gain, delivering 80MHz -3dB bandwidth, 240V/µs slew rate, and 620µA supply current per amplifier. It operates from a single +2.7V to +5.25V supply with rail-to-rail outputs and is packaged in an 8-pin SO (Small Outline) package. It serves as a precision signal conditioning and buffer stage in portable RF front-ends and baseband chains.
For engineers reviewing the MAX4353ESA datasheet, MAX4353ESA pinout, MAX4353ESA application, or MAX4353ESA equivalent, this page provides verified electrical specifications, SO package terminal mapping, real-world use cases in battery-powered communications systems, and validated alternative options for gain-stable high-speed amplification.
Technical Context
The MAX4353ESA employs bipolar process technology and internal compensation optimized for stable operation at closed-loop gains ≥ +5V/V. Its architecture delivers fast large-signal response (8ns rise/fall time, 50ns 1% settling) while maintaining low distortion (–74dBc SFDR at 1MHz, VCC = 3V) across varying capacitive loads up to 22pF.
It features ground-sensing inputs with common-mode range from (VEE – 0.1V) to (VCC – 1.5V), rail-to-rail output swing (within 180mV of rails at 1kΩ), and low input bias current (0.8–3µA). The device is not unity-gain stable and requires external gain-setting resistors for proper AC performance and stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 80MHz - supports wideband analog signal paths such as IF/RF baseband buffers up to cellular LTE channel bandwidths. |
| Slew Rate | 240V/µs - enables clean reproduction of fast transient signals like digital modulation envelopes without slew-induced distortion. |
| Supply Current per Amp | 620µA - allows dual-amplifier operation on <1.3mA total, critical for extended battery life in handheld transceivers. |
| Input Common-Mode Range | VEE – 0.1V to VCC – 1.5V - permits direct interfacing with ADCs and DACs operating near ground or mid-supply references. |
| Output Voltage Swing | Within 180mV of rails (RL = 1kΩ) - maximizes dynamic range in single-supply 3V/5V systems without level-shifting circuitry. |
| Small-Signal Gain Flatness | 4MHz @ 0.1dB - ensures amplitude consistency across multi-MHz signal bands used in keyless entry and portable comms. |
| THD @ 1MHz | –68dB - meets linearity requirements for high-fidelity analog front-ends in audio and sensor signal chains. |
Pinout & Package
The MAX4353ESA is housed in an 8-pin SO (Small Outline) package (SOICN, 150-mil width), compliant with JEDEC MS-012. This surface-mount package supports automated assembly and offers thermal and mechanical reliability for industrial and consumer-grade PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load or next-stage input; rail-to-rail capable, requires isolation resistor for >22pF capacitive loads. |
| 2 | INA– | Inverting input of Amplifier A - connects to feedback network; sensitive to parasitic capacitance; layout must minimize trace length. |
| 3 | INA+ | Noninverting input of Amplifier A - accepts signal source; common-mode range extends to within 0.1V of ground. |
| 4 | VEE | Negative power supply - tied to ground in single-supply configurations; must be bypassed with 0.1µF capacitor near pin. |
| 5 | VCC | Positive power supply - accepts +2.7V to +5.25V; requires local 0.1µF ceramic decoupling to suppress high-frequency noise. |
| 6 | INB– | Inverting input of Amplifier B - electrically isolated from Amplifier A; crosstalk ≤ –74dB at 1MHz ensures channel independence. |
| 7 | INB+ | Noninverting input of Amplifier B - identical electrical characteristics to INA+; supports differential or independent single-ended use. |
| 8 | OUTB | Amplifier B output - fully symmetrical to OUTA; enables dual-channel signal processing without performance trade-offs. |
Key Features
| Feature | Design Value |
|---|---|
| +5V/V minimum stable gain | Enables robust closed-loop designs at gain ≥5 without external compensation, reducing component count in filter/buffer stages. |
| Rail-to-rail output swing | Delivers full 3V or 5V output dynamic range without clipping, eliminating need for level-shifting or dual-supply generation. |
| 620µA per amplifier quiescent current | Supports always-on or low-duty-cycle operation in battery-powered instruments with sub-1.3mA dual-channel draw. |
| 80MHz bandwidth with 240V/µs slew rate | Preserves signal integrity for fast-pulse applications including keyless entry burst transmission and ADC input buffering. |
| Low THD (–68dB) and high SFDR (–74dBc) | Meets spectral purity requirements for baseband signal conditioning in ISM-band transceivers and portable radios. |

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 |
|---|---|---|---|
| MAX4453ESA | Unity-gain stable; 200MHz bandwidth, 95V/µs slew rate, same 620µA supply current and SO package. | Preferred where gain = 1 is required (e.g., voltage followers, ADC input buffers); lower slew rate reduces EMI risk in noise-sensitive layouts. | Select MAX4453ESA when unity-gain stability is mandatory and bandwidth >80MHz is needed; verify layout for higher-frequency stability. |
| LMH6629MA/NOPB | Single 8-pin SO op-amp; 1.5GHz GBW, 1200V/µs slew rate, 5.3mA supply current - significantly higher speed and power. | Used in high-performance instrumentation requiring >100MHz small-signal bandwidth; not suitable for ultra-low-power battery operation. | Choose LMH6629MA/NOPB only when MAX4353ESA's 80MHz bandwidth is insufficient and system power budget allows >5mA per channel. |
Compared with MAX4453ESA and LMH6629MA/NOPB, the MAX4353ESA uniquely balances +5V/V gain stability, 80MHz bandwidth, and sub-1.3mA dual-channel consumption - making it optimal for cost-sensitive, battery-powered RF and sensor interfaces where unity-gain operation is unnecessary.

FAQ
What is the minimum stable closed-loop gain for the MAX4353ESA?
The MAX4353ESA is internally compensated for minimum +5V/V closed-loop gain. It is not unity-gain stable; attempting to operate it at gains below +5V/V may cause oscillation or instability. For unity-gain applications, the pin-compatible MAX4453ESA is recommended instead.
Does the MAX4353ESA support single-supply operation?
Yes, the MAX4353ESA operates from a single +2.7V to +5.25V supply. Its input common-mode range extends from (VEE – 0.1V) to (VCC – 1.5V), and its rail-to-rail output swings within 180mV of both supply rails under 1kΩ load - enabling true single-supply signal chain design.
What package type is used for the MAX4353ESA?
The MAX4353ESA uses an 8-pin SO (Small Outline Integrated Circuit, SOICN) package with 150-mil body width, compliant with JEDEC MS-012. This surface-mount package has standard lead pitch (1.27mm) and is compatible with automated pick-and-place and reflow processes.
Can the MAX4353ESA drive capacitive loads?
The MAX4353ESA is specified to drive up to 22pF capacitive load directly. For larger loads, an isolation resistor (RISO) must be placed in series with the output - values ranging from ~10Ω to 30Ω depending on load capacitance, as shown in Figure 2 of the datasheet, to maintain phase margin and prevent ringing.
How does the MAX4353ESA compare to the MAX4453ESA in terms of bandwidth and stability?
The MAX4353ESA offers 80MHz –3dB bandwidth and is stable only at closed-loop gains ≥ +5V/V, whereas the MAX4453ESA provides 200MHz bandwidth and is unity-gain stable. Both share identical supply current (620µA per amp), rail-to-rail output, and SO packaging - making them functionally complementary within the same family.
