Product details
Overview
MAX4217ESA+ from Maxim Integrated is a dual-channel, precision, closed-loop +2/−1 gain rail-to-rail output buffer IC optimized for high-speed video and instrumentation signal conditioning. It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and 0.03%/0.04° differential gain/phase error while operating from a single 3.15V–11V supply. It is used in video line drivers and ADC interface circuits requiring wide bandwidth and low distortion.
For engineers reviewing the MAX4217ESA+ datasheet, MAX4217ESA+ pinout, MAX4217ESA+ application, or MAX4217ESA+ equivalent, key selection criteria include dual-channel rail-to-rail output swing, fixed internal 500Ω feedback resistors for gain-of-2 or inverting gain-of-1 configurations, low 5.5mA quiescent current per amplifier, and SO-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4217ESA+ implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and bandwidth without sacrificing DC precision. Its internal 500Ω resistors set closed-loop gains of +2V/V (noninverting) or −1V/V (inverting), eliminating external resistor matching requirements.
Each channel features rail-to-rail output swing into 2kΩ loads (within 60mV of rails), input common-mode range extending 100mV beyond VEE, and local output-stage feedback that maintains low output impedance (<200mΩ at 10MHz) and enables ±120mA drive capability while limiting total supply current to 5.5mA per buffer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3dB) | 230MHz - supports full NTSC/PAL video bandwidth and high-speed data acquisition sampling. |
| Slew Rate | 600V/µs - enables clean 2VP-P pulse response with <1ns rise/fall times into 100Ω loads. |
| Output Drive | ±120mA - drives 50Ω/75Ω coaxial cables directly without external buffers. |
| Differential Gain/Phase Error | 0.03%/0.04° - meets broadcast-grade video fidelity requirements for analog video routing. |
| Supply Current (per amp) | 5.5mA - enables dual-channel operation at <11.0mA total, suitable for battery-powered instruments. |
| Input Noise Density | 10nV/√Hz - preserves SNR in low-level signal amplification stages such as CCD imaging front-ends. |
| Operating Supply | Single 3.15V–11V or dual ±1.575V–±5.5V - supports 3.3V, 5V, and ±5V system rails without level-shifting. |
Pinout & Package
MAX4217ESA+ is housed in an 8-pin SO (Small Outline) package with exposed pad thermal enhancement. Pin functions are electrically isolated per channel, enabling independent configuration of each amplifier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A Output | Rail-to-rail output capable of ±120mA sink/source into 50Ω loads; requires no external compensation for stable 230MHz operation. |
| 2 (IN−A) | Amplifier A Inverting Input | 500Ω internal resistor to ground sets −1V/V gain when used as signal input; 56Ω/88Ω termination required for 50Ω/75Ω systems. |
| 3 (IN+A) | Amplifier A Noninverting Input | High-impedance input (3MΩ typical); grounded for +2V/V gain configuration; supports input common-mode down to VEE − 100mV. |
| 4 (VEE) | Negative Power Supply / Ground | Reference node for single-supply operation (0V) or negative rail in dual-supply mode (−5V); substrate tied to this pin. |
| 5 (VCC) | Positive Power Supply | Accepts 3.15V–11V; bypass with 0.1µF ceramic capacitor placed adjacent to pin for high-frequency stability. |
| 6 (IN+B) | Amplifier B Noninverting Input | Independent high-Z input for second channel; identical electrical specs to IN+A; enables dual-path signal conditioning on one die. |
| 7 (IN−B) | Amplifier B Inverting Input | 500Ω internal resistor to ground; supports independent −1V/V gain configuration for channel B without external components. |
| 8 (OUTB) | Amplifier B Output | Fully buffered, rail-to-rail output with matched AC performance to OUTA; all-hostile crosstalk <−95dB at 10MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Precision Resistors | Matched 500Ω feedback network ensures exact +2V/V or −1V/V closed-loop gain without external resistor tolerance errors or layout parasitics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, dual-channel buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6722MA/NOPB | Single-channel, 320MHz bandwidth, 1000V/µs slew rate, no internal gain-setting resistors. | Requires external 500Ω resistors for gain-of-2; higher power (12.5mA per amp); not pin-compatible. | Select when higher bandwidth/slew rate is needed and board area permits external resistor placement. |
| THS3202D | Dual-channel, 375MHz bandwidth, 2000V/µs slew rate, no internal resistors, ±15V supply capable. | Higher supply voltage range (±15V), higher quiescent current (15mA per amp), different pinout and gain configuration method. | Choose for industrial analog signal paths requiring >10V output swing and higher supply headroom. |
Compared with LMH6722MA/NOPB and THS3202D, the MAX4217ESA+ offers integrated gain-setting resistors, lower power (5.5mA/amp), and guaranteed 0.03% differential gain error-making it optimal for compact, low-power video and instrumentation designs where component count and layout simplicity are critical.

FAQ
What is the gain configuration flexibility of the MAX4217ESA+?
The MAX4217ESA+ provides two fixed closed-loop gain options per channel: +2V/V in noninverting mode (ground IN−, apply signal to IN+) or −1V/V in inverting mode (ground IN+, apply signal to IN−). Internal 500Ω resistors eliminate external component requirements, ensuring precise, temperature-stable gain without resistor matching tolerances affecting MAX4217ESA+ performance.
Does the MAX4217ESA+ support single-supply operation?
Yes, the MAX4217ESA+ operates from a single 3.15V to 11V supply with rail-to-rail output swing and input common-mode range extending 100mV beyond VEE (ground in single-supply mode). This enables direct interfacing with 3.3V and 5V logic and sensors without level-shifting circuitry, making MAX4217ESA+ ideal for portable and low-voltage instrumentation.
What is the maximum capacitive load the MAX4217ESA+ can drive stably?
The MAX4217ESA+ is stable driving up to 20pF of capacitive load without external isolation. For loads exceeding 20pF (e.g., long PCB traces or unterminated cables), a series isolation resistor (e.g., 27Ω for 68pF) restores phase margin and suppresses peaking-verified in MAX4217ESA+ typical application curves and confirmed by small-signal gain vs. frequency plots with CL = 47pF/68pF/120pF.
How does the MAX4217ESA+ compare to the MAX4215ESA in terms of channel count and enable functionality?
The MAX4217ESA+ contains two independent amplifiers with no enable/disable feature, whereas the MAX4215ESA is a single-channel device with EN_ pin for shutdown (reducing supply current to 400µA). MAX4217ESA+ is selected when dual-channel buffering is required without power gating; MAX4215ESA suits space-constrained, power-sensitive single-channel applications.
What package type is used for the MAX4217ESA+ and what are its thermal characteristics?
The MAX4217ESA+ uses an 8-pin SO (Small Outline) package with exposed thermal pad (SOIC-N), rated for continuous power dissipation of 471mW at +70°C (derated 5.9mW/°C above). Its thermal resistance θJA is ~110°C/W, supporting reliable operation in compact enclosures when properly heatsinked via the exposed pad to PCB copper.
