Product details
Overview
MAX4270EEE from Maxim Integrated is a dual, ultra-low-distortion, voltage-feedback operational amplifier compensated for minimum stable gain of +5V/V, delivering 200MHz -3dB bandwidth, 900V/µs slew rate, and -56dBc SFDR at 100MHz while driving 100Ω loads - ideal for high-frequency ADC drivers in RF telecom infrastructure.
For engineers reviewing the MAX4270EEE datasheet, MAX4270EEE pinout, MAX4270EEE application, or MAX4270EEE equivalent, this page provides verified circuit role (dual high-speed buffer with disable), exact gain-stability condition (+5V/V min), distortion performance across load and frequency, thermal and supply-current behavior, and validated alternatives for signal-chain design continuity.
Technical Context
The MAX4270EEE implements decompensated bipolar architecture optimized for fixed-gain +5V/V configurations, enabling higher loop gain and improved distortion vs. unity- or +2V/V-compensated variants. Its 200MHz small-signal bandwidth and 200MHz full-power bandwidth support wideband baseband and IF signal conditioning without gain peaking.
Active-low DISABLE_ control per channel enables independent power gating in multiplexed architectures; disable mode reduces quiescent current to 1.6mA per amplifier and places outputs in high-impedance state with 750µs disable time and 100ns enable time - critical for time-interleaved sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 200MHz at AV = +5V/V - supports wideband IF/RF signal paths up to 100MHz fundamental without gain roll-off |
| SFDR @ 100MHz | -56dBc (VOUT = 1Vp-p) - enables clean digitization of high-frequency carriers in 14–16-bit ADC front-ends |
| Slew Rate | 900V/µs - ensures <15ns 0.1% settling for 1V step, critical for fast transient response in DAC buffering |
| Output Drive | ±45mA into 100Ω - maintains linearity while driving heavy resistive loads typical in video and telecom line drivers |
| Voltage Noise Density | 8nV/√Hz at 1kHz - low-noise performance preserves SNR in sensitive receiver chain stages |
| Input Common-Mode Range | (VEE + 1.6V) to (VCC – 1.6V) - accommodates rail-to-rail input signals in single-supply +5V systems |
| Disable Current | 1.6mA per amplifier - reduces total system power by >85% during idle cycles in burst-mode operation |
Pinout & Package
MAX4270EEE is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 1.0mm height), optimized for high-density RF and mixed-signal PCB layouts with low parasitic inductance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | DISABLEA, DISABLEB | Active-low disable inputs - independently gate each amplifier; logic low places output in high-Z state |
| 2, 9 | INA-, INB- | Inverting inputs - accept differential or single-ended feedback networks for +5V/V gain configuration |
| 3, 10 | INA+, INB+ | Noninverting inputs - reference nodes for precision DC-coupled signal conditioning |
| 4, 5 | VEE | Negative supply pin - tied to ground in single-supply operation; supports dual ±2.25V to ±4.0V |
| 6, 7 | OUTA, OUTB | Amplifier outputs - deliver ±45mA into 100Ω with 1.1V rail headroom; high-Z when disabled |
| 11, 12 | N.C. | No internal connection - must remain unconnected per datasheet; no routing or grounding required |
| 13, 14 | VCC | Positive supply pin - operates from +4.5V to +8.0V; requires 1nF || 0.1µF ceramic bypassing |
| 15, 16 | DISABLEA, DISABLEB | Duplicate disable pins - electrically identical to Pins 1 & 8; used for layout flexibility and noise reduction |
Key Features
| Feature | Design Value |
|---|---|
| +5V/V minimum gain compensation | Enables higher closed-loop gain stability margin and lower distortion than +2V/V variants at same frequency |
| Per-channel disable control | Allows independent power gating of amplifiers in time-multiplexed signal chains without cross-talk |
| 200MHz 0.1dB gain flatness | Maintains amplitude fidelity across 35MHz bandwidth - essential for wideband IF amplification |
| 35dBm IP3 @ 20MHz | Supports linear amplification of multi-tone RF signals with minimal intermodulation in base-station receivers |
| 100Ω load drive capability | Eliminates need for external output buffers in 50Ω/100Ω transmission-line interfaces |
| Low 1.6mA disable current | Reduces standby power in battery-backed or energy-constrained instrumentation systems |

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 |
|---|---|---|---|
| MAX4269EEE | +2V/V minimum gain compensation; 350MHz -3dB bandwidth; -59dBc SFDR @ 100MHz | Better bandwidth but reduced gain stability margin; suited for +2V/V gain stages with tighter layout constraints | Select when system requires higher small-signal bandwidth and can accommodate lower gain setting |
| LMH6629MA/NOPB | Unity-gain stable; 1.5GHz GBW; 1000V/µs slew rate; -62dBc SFDR @ 100MHz (RL = 100Ω) | Higher bandwidth and slew rate but lacks per-channel disable; single-supply only (+5V) | Choose for ultra-wideband unity-gain buffers where independent disable is not required |
Compared with MAX4269EEE and LMH6629MA/NOPB, the MAX4270EEE trades 150MHz bandwidth for superior +5V/V gain stability, lower distortion at high output swing, and independent disable control - making it optimal for fixed-gain, power-gated, high-linearity signal chains.

FAQ
What is the minimum stable gain requirement for MAX4270EEE?
The MAX4270EEE is internally compensated for a minimum stable closed-loop gain of +5V/V. Operating below this gain may cause instability or peaking in frequency response. This distinguishes it from the unity-gain stable MAX4268EEE and +2V/V-stable MAX4269EEE within the same family. Always verify gain configuration against the MAX4270EEE datasheet's compensation guidelines before layout.
Does MAX4270EEE support single-supply operation?
Yes, MAX4270EEE operates from a single +4.5V to +8.0V supply, with VEE pins connected to ground. Input common-mode range extends from (VEE + 1.6V) to (VCC – 1.6V), enabling DC-coupled operation with 1.6V headroom from each rail. For optimal PSRR and CMRR, use tight 1nF || 0.1µF ceramic bypassing at VCC and ground.
How does the disable function work on MAX4270EEE?
MAX4270EEE features two independent active-low DISABLE_ inputs (Pins 1/8 and 15/16), one per amplifier. Pulling either pin low disables its respective output and reduces quiescent current to 1.6mA per channel. Outputs enter high-impedance state with 750µs disable time and 100ns enable time - confirmed in the MAX4270EEE datasheet's AC Electrical Characteristics table.
What load impedance is MAX4270EEE specified to drive?
MAX4270EEE is fully characterized driving a 100Ω load to VCC/2, delivering ±45mA output current while maintaining -56dBc SFDR at 100MHz and 900V/µs slew rate. It also supports 150Ω loads (e.g., NTSC video) with 0.01% differential gain error. For capacitive loads >15pF, an isolation resistor (e.g., 22Ω for 22pF) is required per Figure 2 in the MAX4270EEE datasheet.
Is MAX4270EEE pin-compatible with other devices in the MAX4265–MAX4270 family?
No - MAX4270EEE uses a 16-pin QSOP package shared only with MAX4268EEE and MAX4269EEE, but pin functions differ significantly. For example, MAX4270EEE assigns Pins 1/8/15/16 to DISABLE_, whereas MAX4268EEE uses Pins 1/8 for DISABLE_ and Pins 15/16 for VCC. Always consult the Pin Configuration table in the MAX4270EEE datasheet before board reuse.
