Product details
Overview
MAX4269EEE from Maxim Integrated is a dual, ultra-low-distortion, voltage-feedback operational amplifier compensated for minimum stable gain of +2V/V, delivering 350MHz small-signal bandwidth, -59dBc SFDR at 100MHz (1Vp-p, 100Ω), and 900V/µs slew rate. It operates from single +4.5V to +8.0V or dual ±2.25V to ±4.0V supplies and features active-low disable control per channel, enabling high-impedance output state for power-sensitive RF telecom and ADC driver applications.
For engineers reviewing the MAX4269EEE datasheet, MAX4269EEE pinout, MAX4269EEE application, or MAX4269EEE equivalent, key selection criteria include its dual-channel architecture with independent disable inputs, 16-pin QSOP package, 200MHz full-power bandwidth into 1Vp-p, 35dBm IP3 at 20MHz, and verified performance driving 100Ω loads in high-frequency signal chains.
Technical Context
The MAX4269EEE employs proprietary bipolar process technology optimized for low-voltage, high-speed operation-achieving distortion performance typically found only in dual-supply op amps. Its decompensated +2V/V configuration provides higher loop gain and improved SFDR versus unity-gain variants, with measured -59dBc spurious-free dynamic range at 100MHz under 1Vp-p output swing into 100Ω.
Each amplifier channel includes an independent active-low DISABLE_ input that reduces quiescent current to 1.6mA per amp and places outputs in high-impedance state within 100ns enable time. The device maintains 100MHz 0.1dB gain flatness and supports rail-to-rail input common-mode range (VEE + 1.6V to VCC – 1.6V) while delivering ±45mA output drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal BW (-3dB) | 350MHz - Enables wideband IF amplification up to UHF band without gain peaking. |
| SFDR @ 100MHz | -59dBc (1Vp-p, 100Ω) - Critical for preserving signal integrity in high-order QAM and OFDM baseband paths. |
| Slew Rate | 900V/µs - Supports clean 100MHz sine-wave generation with <0.1% THD+N up to 2.5Vp-p. |
| Input Voltage Noise | 8nV/√Hz @ 1kHz - Low-noise front-end suitable for 16-bit ADC buffering without SNR degradation. |
| Output Drive | ±45mA - Sustains 1Vp-p into 100Ω load while maintaining distortion specs across -40°C to +85°C. |
| Disable Current | 1.6mA per amplifier - Reduces system standby power by >90% vs. active mode (28mA typical). |
| IP3 @ 20MHz | 35dBm - Ensures linear operation in two-tone RF receiver stages with minimal intermodulation. |
Pinout & Package
The MAX4269EEE is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 1.0mm height) with exposed pad for thermal enhancement. Pin pitch is 0.635mm; recommended reflow profile complies with JEDEC J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | DISABLEA, DISABLEB | Active-low disable control for each amplifier; logic low forces output high-Z and cuts supply current. |
| 2, 9 | INA-, INB- | Inverting inputs; support differential or single-ended configurations with 40kΩ differential input resistance. |
| 3, 10 | INA+, INB+ | Noninverting inputs; common-mode range extends to within 1.6V of rails for flexible biasing. |
| 4, 5 | VEE | Negative supply pin; tied to GND in single-supply operation; max |VCC–VEE| = +8.5V absolute rating. |
| 6, 7 | OUTA, OUTB | Amplifier outputs; capable of ±45mA sourcing/sinking into resistive loads with <1.1V rail headroom. |
| 13, 14 | VCC | Positive supply input; accepts +4.5V to +8.0V; requires 1nF || 0.1µF ceramic bypassing per supply pin. |
| 11, 12 | N.C. | No internal connection; must remain unconnected per datasheet to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent disable control | Enables per-channel power gating in multiplexed signal paths without PCB layout changes. |
| +2V/V minimum stable gain | Delivers higher loop gain than unity-gain variants, improving distortion and bandwidth trade-off at 2× gain setting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8009ARZ | Single-channel, unity-gain stable, 1GHz bandwidth, but higher 13nV/√Hz noise and no disable function. | Lacks per-channel disable and dual-channel integration; requires two devices for same functionality. | Select when >500MHz bandwidth is mandatory and power gating is not required. |
| LMH6629MF/NOPB | Single-channel, +2V/V stable, 720MHz bandwidth, 1.9nV/√Hz noise, but no disable and SO-8 packaging only. | Higher bandwidth and lower noise, but no integrated disable and no dual-channel option in same footprint. | Select when ultra-low noise dominates over power management and board space constraints allow discrete dual placement. |
Compared with AD8009ARZ and LMH6629MF/NOPB, the MAX4269EEE uniquely combines dual-channel operation, per-amplifier disable, 350MHz bandwidth with -59dBc SFDR at 100MHz, and 16-pin QSOP packaging-making it optimal for space-constrained, power-aware RF signal chains requiring matched channel performance.

FAQ
What is the maximum supply voltage for the MAX4269EEE?
The MAX4269EEE supports a maximum supply voltage of +8.5V between VCC and VEE pins. Operation is specified from +4.5V to +8.0V on VCC with VEE grounded in single-supply mode, or ±2.25V to ±4.0V in dual-supply configuration. Exceeding +8.5V differential may cause permanent damage per Absolute Maximum Ratings.
Does the MAX4269EEE support unity-gain stable operation?
No, the MAX4269EEE is not unity-gain stable. It is internally compensated for a minimum stable closed-loop gain of +2V/V. Attempting unity-gain operation risks instability and oscillation. For unity-gain applications, use the MAX4268EEE instead, which shares the same 16-pin QSOP package and dual-channel architecture.
How does the disable function affect output impedance in the MAX4269EEE?
When DISABLEA or DISABLEB is pulled low, the corresponding amplifier output enters a true high-impedance state with leakage current ≤2.5µA and disabled output capacitance of 5pF. This allows safe multiplexing of multiple MAX4269EEE channels onto shared signal paths without loading or crosstalk penalties during inactive periods.
What is the full-power bandwidth of the MAX4269EEE and why does it matter?
The MAX4269EEE has a full-power bandwidth of 200MHz (1Vp-p output into 100Ω). This specification defines the highest frequency at which the amplifier can deliver its rated output voltage swing without slew-rate limiting. It directly determines usable signal bandwidth in applications like IF amplification and high-speed DAC buffering where large-signal fidelity is essential.
Can the MAX4269EEE drive a 50Ω load while maintaining specified distortion performance?
Yes-the MAX4269EEE is characterized driving 100Ω loads, but its ±45mA output drive capability supports 50Ω termination with minor derating. At 50Ω, SFDR degrades by ~3dB compared to 100Ω (e.g., -56dBc at 100MHz), and output swing reduces to ~0.8Vp-p. Layout must minimize trace inductance and use proper 50Ω source termination to maintain stability.
