Product details
Overview
MAX4215EUA from Maxim Integrated is a precision, single-supply, rail-to-rail output, closed-loop buffer with fixed gain of +2V/V or −1V/V, 230MHz −3dB bandwidth, 600V/µs slew rate, and enable/disable functionality. It operates from 3.15V to 11V single supply (or ±1.575V to ±5.5V dual), draws only 5.5mA quiescent current, and delivers ±120mA output drive-ideal for video line driving and ADC interface in space-constrained industrial instrumentation.
For engineers reviewing the MAX4215EUA datasheet, MAX4215EUA pinout, MAX4215EUA application, or MAX4215EUA equivalent, this page provides verified electrical specs, µMAX-8 package terminal mapping, real-world video/RF signal-chain use cases, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX4215EUA employs voltage-feedback architecture enhanced with current-feedback techniques to achieve high-speed performance while maintaining precision DC characteristics. Its internal 500Ω resistors set closed-loop gain without external components, and local feedback around the output stage ensures low output impedance (<200mΩ at 10MHz) and demand-driven biasing for ±120mA drive capability.
It features rail-to-rail output swing (within 60mV of rails into 2kΩ), input common-mode range extending 100mV beyond VEE, and integrated enable logic (EN_ pin) that reduces supply current to 400µA per buffer when asserted low. Differential gain/phase error is specified at 0.03%/0.04° for NTSC video compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3dB) | 230MHz - supports full HD video baseband and RF IF signals up to ~115MHz fundamental |
| Slew Rate | 600V/µs - enables clean 2VP-P step response in <1ns with minimal overshoot |
| Supply Current (active) | 5.5mA - allows battery-powered portable instruments to operate >10 hours on 2×AA cells |
| Supply Current (shutdown) | 400µA - reduces system standby power by >92% vs active mode |
| Output Drive | ±120mA - drives 50Ω coaxial cable directly without external buffer stage |
| Input Noise Density | 10nV/√Hz - preserves SNR in low-level analog front-ends like CCD imaging systems |
| Differential Gain/Phase | 0.03%/0.04° - meets broadcast-grade NTSC/PAL video fidelity requirements |
Pinout & Package
The MAX4215EUA is housed in an 8-pin µMAX package (3.0mm × 3.0mm, 0.8mm height), pin-compatible with industry-standard 8-pin SO and µSOP footprints. It uses exposed-pad thermal design for improved power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting Input | 500Ω input impedance; used for −1V/V gain configuration or termination in 50Ω/75Ω systems |
| 2 (IN+) | Noninverting Input | High-impedance node; used for +2V/V gain when IN− is grounded |
| 3 (VEE) | Negative Supply / Ground | Reference for single-supply operation; input common-mode extends 100mV below this rail |
| 4 (EN) | Enable Control Input | Active-low logic: pulls supply current to 400µA when ≤0.075V above VEE |
| 5 (OUT) | Buffer Output | Rail-to-rail capable; drives ±120mA into resistive loads or 50Ω transmission lines |
| 6 (N.C.) | No Connection | Not internally bonded; must be left floating or tied to ground per layout best practices |
| 7 (VCC) | Positive Supply | Accepts 3.15V–11V single supply; bypass with 0.1µF ceramic capacitor close to pin |
| 8 (N.C.) | No Connection | Not internally bonded; same handling as Pin 6 |
Key Features
| Feature | Design Value |
|---|---|
| Fixed closed-loop gain | Internal 500Ω resistors eliminate external gain-setting components and reduce board area by ≥30% vs discrete solutions |

| Low distortion at 5MHz | −72dBc SFDR and −71dB THD enable clean digitization of composite video or IF signals in ADC front-ends |
| Enable/disable control | Reduces ICC to 400µA per buffer-enables power-gating in multi-channel video routing systems without signal path interruption |
| Input protection diodes | Back-to-back Schottky clamps between IN+ and IN− prevent latch-up during hot-plug or ESD events in field-deployed equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DR | Higher 1.8GHz bandwidth but no internal gain resistors; requires external feedback network and dual ±5V supplies | Used in wideband RF test equipment where gain flexibility > fixed gain; not suitable for single-supply 3.3V video systems | Select THS3201DR only when variable gain, >1GHz bandwidth, and dual-supply operation are required-avoid for cost-sensitive, space-constrained video line drivers. |
| ADA4857-1ARZ | Lower 1GHz bandwidth, 250V/µs slew rate, and no enable pin; offers lower 4.2nV/√Hz voltage noise but higher 2.5pA/√Hz current noise | Favored in precision instrumentation requiring ultra-low voltage noise over speed; lacks shutdown for power-gated systems | Choose ADA4857-1ARZ for low-noise sensor signal conditioning where 230MHz bandwidth is excessive; reject for video routing with dynamic power management needs. |
Compared with THS3201DR and ADA4857-1ARZ, the MAX4215EUA uniquely combines fixed +2/−1 gain, single-supply rail-to-rail operation, enable control, and NTSC-grade video fidelity-making it the only option among the three qualified for battery-powered video multiplexers with strict PCB area and power budgets.

FAQ
What is the operating supply voltage range for the MAX4215EUA?
The MAX4215EUA operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. At 3.3V operation, it maintains full 230MHz bandwidth and rail-to-rail output swing into 2kΩ. The device is fully specified across −40°C to +85°C, with guaranteed performance at 3.15V minimum to support Li-ion battery-powered systems down to end-of-discharge voltage.
Does the MAX4215EUA require external gain-setting resistors?
No, the MAX4215EUA does not require external gain-setting resistors. It integrates precision 500Ω thin-film resistors to provide fixed closed-loop gains of +2V/V (noninverting, with IN− grounded) or −1V/V (inverting, with IN+ grounded). This eliminates resistor matching errors, reduces PCB area, and improves temperature stability versus discrete resistor networks-key for video gain accuracy.
How does the enable (EN) pin function on the MAX4215EUA?
The EN pin on the MAX4215EUA is an active-low digital control input. When pulled ≤0.075V above VEE, it disables the amplifier core and reduces quiescent supply current to 400µA per buffer. Rise/fall times are <100ns, and disable time is <1µs. The output enters high-impedance state with 1kΩ disabled output resistance-enabling safe signal-path isolation in video switch matrices without external analog switches.
Can the MAX4215EUA drive 50Ω transmission lines directly?
Yes, the MAX4215EUA can drive 50Ω transmission lines directly. Its ±120mA output current capability and 200mΩ output impedance at 10MHz allow it to deliver full 2VP-P into 50Ω with <0.1dB gain flatness up to 90MHz. For optimal return loss, terminate the far end with 50Ω and use microstrip layout with controlled impedance-no series isolation resistor needed for ≤20pF load capacitance.
What is the input common-mode voltage range of the MAX4215EUA?
The input common-mode voltage range of the MAX4215EUA extends from (VEE − 0.1V) to (VCC − 2.25V). In single-supply 5V operation (VEE = 0V), this means inputs can swing from −100mV to +2.75V-enabling ground-sensing capability for true single-supply operation. This range is guaranteed over temperature and supports DC-coupled video and sensor interfaces without level-shifting circuitry.
