Analog Devices Inc./Maxim Integrated MAX4030EEUA+T

Overview

MAX4030EEUA+T from Maxim Integrated is a dual, unity-gain stable, rail-to-rail output operational amplifier optimized for high-speed video line driving with ±15kV ESD protection on inputs and outputs. It operates from a single 5V supply, delivers 144MHz small-signal bandwidth, 115V/µs slew rate, and drives 150Ω video loads while maintaining 0.2% differential gain and 0.2° differential phase error - enabling SDTV, HDTV, and security camera signal conditioning.

For engineers reviewing the MAX4030EEUA+T datasheet, MAX4030EEUA+T pinout, MAX4030EEUA+T application, or MAX4030EEUA+T equivalent, key selection criteria include ESD-hardened video interface performance, 8-pin µMAX package compatibility, rail-to-rail output swing to within 100mV of rails, and guaranteed -40°C to +85°C operation without external compensation.

Technical Context

The MAX4030EEUA+T employs BiCMOS process technology to achieve high slew rate (115V/µs) and wide bandwidth (144MHz) while maintaining unity-gain stability and low input bias current (0.01µA). Its ground-sensing input stage supports common-mode voltage down to GND, and rail-to-rail output stage uses local feedback to maintain low open-loop output impedance (<2Ω at 4.43MHz), ensuring consistent gain flatness into reactive loads.

ESD protection is implemented via integrated structures on all pins, validated per ±15kV Human Body Model, ±8kV IEC 1000-4-2 contact discharge, and ±15kV IEC 1000-4-2 air-gap discharge - eliminating need for external TVS diodes in exposed video I/O paths. The device is internally compensated and requires no external components for stable unity-gain operation.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load the MAX4030EEUA+T can drive stably?

The MAX4030EEUA+T is stable with up to 200pF capacitive load when isolated by a series resistor ≥10Ω. Without isolation, oscillation may occur above ~5pF due to reduced phase margin. Figure 4 in the datasheet provides optimal RISO values versus load capacitance, and Figure 6 demonstrates stable closed-loop response with 10Ω isolation into 20pF. This behavior is confirmed across the full -40°C to +85°C range.

Does the MAX4030EEUA+T require external compensation for unity-gain operation?

No, the MAX4030EEUA+T is internally compensated for unity-gain stability and requires no external components to operate reliably at gain = 1. The datasheet explicitly states "internally compensated for unity gain" and recommends a 24Ω feedback resistor in unity-gain configurations to optimize AC performance by damping parasitic LC resonance. This design eliminates layout sensitivity and reduces bill-of-materials cost.

Can the MAX4030EEUA+T drive a 75Ω video load directly?

Yes, the MAX4030EEUA+T is specified to directly drive 150Ω loads, and its output stage is robust enough to handle 75Ω with minor degradation in swing and distortion. Typical output voltage swing into 75Ω remains >3.8Vpp (from 0.2V to 4.0V) at 5V supply, and differential gain/phase remain within 0.25%/0.25° at NTSC - meeting most SDTV and security camera requirements. For production-critical 75Ω designs, verify thermal dissipation (max 362mW at +70°C) and layout per Figure 1 guidelines.

What is the input common-mode voltage range of the MAX4030EEUA+T?

The MAX4030EEUA+T input common-mode voltage range extends from GND (0V) to VCC − 2.25V (2.75V at 5V supply), enabling true single-supply operation with DC-coupled inputs. This ground-sensing capability is guaranteed over the full -40°C to +85°C temperature range and supports applications such as video clamping, level shifting, and sensor signal conditioning where input signals reference system ground.

Is the MAX4030EEUA+T pin-compatible with other packages of the same part number?

Yes, the MAX4030EEUA+T (8-pin µMAX) shares identical pinout and electrical functionality with the MAX4030EESA (8-pin SO), as confirmed in the Pin Configurations section and Ordering Information table. Both packages use the same pin numbering: OUTA, INA−, INA+, GND, INB+, INB−, OUTB, VCC. Layout conversion between µMAX and SO requires only footprint adaptation - no schematic or signal routing changes are needed.
