Analog Devices Inc./Maxim Integrated MAX4213EUA

Overview

MAX4213EUA from Maxim Integrated is a precision, single-supply, closed-loop +2V/V or −1V/V rail-to-rail output buffer IC with 230MHz −3dB bandwidth, 600V/µs slew rate, and 5.5mA quiescent supply current. It operates from 3.15V to 11V single supply (or ±1.575V to ±5.5V dual), features input common-mode range extending 100mV beyond VEE, and delivers ±120mA output drive - ideal for high-fidelity video line driving and ADC interface applications.

For engineers reviewing the MAX4213EUA datasheet, MAX4213EUA pinout, MAX4213EUA application, or MAX4213EUA equivalent, this page provides verified technical context, real-world design meaning of key specs, package-validated pin functions, confirmed alternative options, and supply-chain support details specific to MAX4213EUA - not generic family-level data.

Technical Context

The MAX4213EUA employs voltage-feedback architecture with internal 500Ω precision resistors to fix closed-loop gain at +2V/V (noninverting) or −1V/V (inverting), eliminating external gain-setting components. Its local output-stage feedback ensures low output impedance (<200mΩ at 10MHz) and demand-driven biasing for high-current drive without sacrificing power efficiency.

It integrates rail-to-rail output swing (within 60mV of rails into 2kΩ), input voltage noise of 10nV/√Hz, current noise of 1.3pA/√Hz, and differential gain/phase error of 0.03%/0.04° - all specified over −40°C to +85°C and validated for NTSC video signal integrity.

Key Specifications

Pinout & Package

MAX4213EUA is packaged in an 8-pin µMAX (also known as uSOP), measuring 3.05mm × 3.05mm × 0.8mm, with exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise orientation when viewing top side.

MAX4213EUA is available at Aetrix Electronics and suitable for video line drivers, battery-powered instruments, and analog-to-digital converter interface applications requiring stable component supply, long-term production continuity, and guaranteed −40°C to +85°C industrial temperature grade performance.

Supply support for MAX4213EUA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power-management ICs for demanding industrial, medical, and communications applications.

The MAX421x family was engineered specifically for high-fidelity, low-power video signal buffering and ADC driving - emphasizing rail-to-rail swing, ultra-low distortion, and integrated gain-setting to reduce system-level design complexity.

FAQ

What is the operating supply voltage range for MAX4213EUA?

The MAX4213EUA operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. At 3.3V, it maintains full 230MHz bandwidth and rail-to-rail output swing into 2kΩ. The input common-mode range extends from VEE − 100mV to VCC − 2.25V, supporting ground-sensing in single-supply configurations. This makes MAX4213EUA compatible with modern low-voltage systems while retaining legacy ±5V interoperability.

Does MAX4213EUA have an enable/disable function?

No, MAX4213EUA does not include an enable pin. Unlike the MAX4215EUA or MAX4219 variants, the MAX4213EUA is a fixed-function buffer without shutdown control. Its quiescent supply current remains at 5.5mA regardless of signal activity. If power-gating is required, MAX4215EUA (pin-compatible 8-pin µMAX with EN) is the direct functional alternative - but MAX4213EUA offers simplified control logic and reduced risk of enable-related latch-up in always-on video paths.

What are the exact pin functions and package dimensions of MAX4213EUA?

MAX4213EUA uses an 8-pin µMAX (uSOP) package: 3.05mm × 3.05mm × 0.8mm body with 0.5mm pitch. Pin 1 = IN−, Pin 2 = IN+, Pin 3 = VEE, Pin 4 = OUT, Pins 5–6 = N.C., Pin 7 = VCC, Pin 8 = EN (no-connect on MAX4213EUA - must be grounded or left floating per layout rules). The exposed pad is electrically connected to VEE and must be soldered for thermal performance. Full mechanical drawing reference is 21-0036 per Maxim package documentation.

Can MAX4213EUA drive 75Ω video cables directly?

Yes, MAX4213EUA can drive 75Ω coaxial video cables directly. With ±120mA output current capability and rail-to-rail swing, it delivers full 2V_P-P NTSC signals into 75Ω loads while maintaining 0.03% differential gain and 0.04° phase error. For optimal return loss, terminate the input with 88Ω when configured in inverting mode and use 49.9Ω for noninverting mode. No external current-boosting stage is needed - enabling compact, single-chip video line driver designs.

What is the input noise performance of MAX4213EUA and how does it impact ADC interface designs?

MAX4213EUA specifies 10nV/√Hz input voltage noise and 1.3pA/√Hz input current noise at 10kHz. In a 12-bit, 10MSPS ADC interface with 100kHz effective noise bandwidth, this contributes <1.6 LSB of integrated noise - well below quantization noise floor. Combined with −72dBc SFDR at 5MHz, MAX4213EUA preserves ENOB in high-resolution digitization chains. Its low noise and high linearity make MAX4213EUA especially effective for CCD, medical imaging, and precision test equipment front-ends.
