Product details
Overview
MAX4454ESD+T from Maxim Integrated is a quad, unity-gain stable, rail-to-rail output operational amplifier optimized for low-power, high-speed signal conditioning in single-supply systems. It delivers 200MHz -3dB bandwidth, 95V/µs slew rate, and consumes only 620µA per amplifier across +2.7V to +5.25V operation - enabling use in battery-powered RF front-ends and portable baseband circuits.
For engineers reviewing the MAX4454ESD+T datasheet, MAX4454ESD+T pinout, MAX4454ESD+T application, or MAX4454ESD+T equivalent, key selection criteria include its unity-gain stability, 14-pin SO package footprint, rail-to-rail output swing (within 180mV of rails), low input offset voltage (0.4–12mV), and verified performance in ADC buffer and active filter roles at 1–15MHz frequencies.
Technical Context
The MAX4454ESD+T employs a bipolar voltage-feedback architecture with internal unity-gain compensation, ensuring stability without external components in gain ≥1 configurations. Its rail-to-rail output stage uses demand-driven current biasing to maintain low open-loop output impedance (<0.8Ω at 1MHz) across load variations.
Input common-mode range extends from VEE − 0.1V to VCC − 1.5V, supporting ground-sensing operation; output swings to within 180mV of either rail under 1kΩ load. It is not optimized for highly capacitive loads (>22pF) without series isolation resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 200MHz - supports wideband signal amplification up to cellular IF frequencies without gain peaking. |
| Slew Rate | 95V/µs - enables clean 2V-step response with 20ns rise/fall time for fast transient fidelity. |
| Supply Current | 620µA per amplifier - allows four-channel operation at <2.5mA total, critical for coin-cell or Li-ion portable designs. |
| Input Offset Voltage | 0.4mV typical (12mV max) - minimizes DC error in precision sensor interfaces and instrumentation front-ends. |
| Output Swing | Within 180mV of VCC/VEE (1kΩ load) - maximizes dynamic range in 3V/5V single-supply data acquisition systems. |
| Input Noise Density | 15nV/√Hz at 10kHz - suitable for low-noise preamplification before high-resolution ADCs. |
| CMRR | 60–100dB - rejects common-mode interference in noisy mixed-signal PCB environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad, rail-to-rail, high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4454EUD+ | Same electrical specs, but in 14-pin TSSOP (4.4mm width) instead of SO (8.75mm width); 0.65mm pitch vs. 1.27mm. | TSSOP offers higher board density but requires finer-pitch reflow; SO suits legacy through-hole-compatible layouts and manual prototyping. | Select MAX4454EUD+ for space-constrained PCBs; choose MAX4454ESD+T for mechanical robustness, thermal mass, and compatibility with standard SO footprints. |
| AD8044ARZ | Higher supply current (12.5mA total), wider bandwidth (160MHz), but not unity-gain stable - requires minimum gain of +2V/V. | Not suitable for unity-gain buffers or DC-coupled integrators; better for fixed-gain video or composite signal paths. | Choose AD8044ARZ only if gain ≥2 is acceptable and higher power budget exists; MAX4454ESD+T remains preferred for low-power, unity-gain, rail-to-rail use cases. |
Compared with MAX4454EUD+, the MAX4454ESD+T provides identical AC/DC performance in a larger, more thermally stable SO package - simplifying layout, easing hand-soldering, and improving long-term reliability in industrial temperature cycling. Against AD8044ARZ, it trades bandwidth for guaranteed unity-gain stability and 5× lower quiescent current.

FAQ
What is the operating supply voltage range for the MAX4454ESD+T?
The MAX4454ESD+T operates from a single +2.7V to +5.25V supply. This range is guaranteed by PSRR testing and supports both 3V and 5V system rails. Operation outside this range may cause permanent damage, and absolute maximum supply voltage is +6V. The device draws only 620µA per amplifier across this full voltage span, making it ideal for wide-input-voltage portable designs where battery voltage varies significantly during discharge.
Is the MAX4454ESD+T unity-gain stable?
Yes, the MAX4454ESD+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 is confirmed in the General Description, Selector Guide, and Applications Information sections of the datasheet. In contrast, the pin-compatible MAX4354 variant requires a minimum closed-loop gain of +5V/V and is not unity-gain stable.
What is the output voltage swing specification for the MAX4454ESD+T?
The MAX4454ESD+T delivers rail-to-rail output swing, reaching within 180mV of VCC and within 75mV of VEE (GND) under 1kΩ load conditions. At VCC = +5V, this means VOH ≥ 4.82V and VOL ≤ 0.075V. This wide dynamic range preserves signal fidelity in low-voltage systems and improves effective resolution when driving ADCs or comparators referenced to the same supply rails.
Can the MAX4454ESD+T drive capacitive loads directly?
The MAX4454ESD+T is optimized for resistive loads and is not designed to drive highly reactive or large capacitive loads (>22pF) directly. Doing so risks instability, ringing, or oscillation due to reduced phase margin. The datasheet recommends using an isolation resistor (RISO) in series with the output when driving capacitive loads - with RISO values ranging from ~10Ω to 30Ω depending on load capacitance, as shown in Figure 2 and toc31/toc39.
How many independent amplifiers does the MAX4454ESD+T contain, and how are they isolated?
The MAX4454ESD+T contains four fully independent operational amplifiers (A, B, C, D) on a single die. Each has dedicated input and output pins with no shared internal nodes. Crosstalk between channels is specified at ≤ −74dB at 1MHz, confirming functional isolation. Power supply rejection (PSRR) and common-mode rejection (CMRR) are maintained per channel, and each amplifier draws its own 620µA quiescent current - enabling true parallel signal processing without interaction.
