Product details
Overview
MAX4454ESD+ 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 20ns rise/fall times while consuming only 620µA per amplifier across +2.7V to +5.25V supply. It is used in baseband signal paths of portable communications equipment such as keyless entry transceivers and cellular handset front-ends.
For engineers reviewing the MAX4454ESD+ datasheet, MAX4454ESD+ pinout, MAX4454ESD+ application, or MAX4454ESD+ equivalent, this page provides verified electrical specifications, SO-14 package terminal mapping, real-world use cases in battery-powered RF interfaces, and validated alternative op-amps with documented gain-bandwidth and power trade-offs.
Technical Context
The MAX4454ESD+ employs voltage-feedback architecture with internal compensation for stable unity-gain operation. 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 each 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 amplification of low-level analog signals without DC level shifting in single-supply configurations.

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 |
|---|---|---|---|
| MAX4454EUD+ | TSSOP-14 package; same electrical specs but 5mm × 4.4mm footprint vs. SO-14's 8.65mm × 3.9mm | Better thermal performance in dense layouts; requires different stencil aperture and reflow profile | Select for space-constrained PCBs where height clearance permits TSSOP; avoid if legacy SO-14 footprint must be retained |
| AD8054ARZ | 220MHz bandwidth, 145V/µs slew rate, 5.5mA per amp - 9× higher supply current than MAX4454ESD+ | Higher drive capability for 50Ω transmission lines; unsuitable for battery-critical designs | Choose when driving coaxial cables or high-capacitance loads (>100pF); not recommended for >72-hour battery life targets |
Compared with MAX4454EUD+, the MAX4454ESD+ offers identical analog performance in a larger, more manufacturable SO package with proven reliability in automotive-grade reflow cycles; versus AD8054ARZ, it trades raw speed for 90% lower quiescent power - making it optimal for always-on sensing nodes rather than lab-grade instrumentation.

FAQ
What is the maximum capacitive load the MAX4454ESD+ can drive without instability?
The MAX4454ESD+ is not optimized for highly reactive loads. Driving >22pF directly may cause ringing or oscillation due to reduced phase margin. For capacitive loads exceeding 22pF, an isolation resistor (RISO) must be placed in series with the output - e.g., 18Ω for 50pF load per Figure 2 in the datasheet. This maintains stability while preserving bandwidth in ADC buffer and filter applications using the MAX4454ESD+.
Does the MAX4454ESD+ support true rail-to-rail input operation?
No, the MAX4454ESD+ features rail-to-rail *output* but has a limited input common-mode range of (VEE − 0.1V) to (VCC − 1.5V). At VCC = 3V, this means inputs must stay between −0.1V and +1.5V - excluding the upper 1.5V near VCC. It is ground-sensing, not rail-sensing. For full rail-to-rail input, consider alternatives like the MAX4478; the MAX4454ESD+ remains optimal where output swing is the critical constraint.
Can the MAX4454ESD+ be used in inverting configuration with gain = −1?
Yes, the MAX4454ESD+ supports stable inverting configurations including gain = −1. Use equal-value resistors (e.g., 1kΩ) for RF and RG, and add RS = 500Ω (parallel of RF//RG) from noninverting input to ground to minimize input offset errors. Layout must minimize parasitic capacitance at the inverting node - keep traces short and avoid vias - since the MAX4454ESD+'s 200MHz bandwidth makes it sensitive to stray reactance that could degrade phase margin.
What is the typical input offset voltage drift over temperature for the MAX4454ESD+?
The MAX4454ESD+ has a typical input offset voltage temperature coefficient (TCVOS) of 7µV/°C. Over the full −40°C to +85°C operating range, this results in a worst-case drift of ±0.875mV relative to the 25°C value. The datasheet specifies a max VOS of 12mV at TA = +25°C, so total offset across temperature remains within 12.875mV - sufficient for most portable instrument and communication front-end applications using the MAX4454ESD+.
Is the MAX4454ESD+ pin-compatible with other quad op-amps in SO-14 packages?
No, the MAX4454ESD+ uses a proprietary pinout optimized for quad-channel symmetry and low crosstalk - distinct from industry-standard SO-14 op-amps like the LM324 or TL074. Pin 1 is OUTD, not VCC or IN+. Substituting without board redesign will cause functional failure. Always verify pin mapping before replacement; the MAX4454ESD+ pinout is documented in the "Pin Configurations" section of its datasheet.
