Product details
Overview
MAX4074CAEUK-T from Maxim Integrated is a micropower, fixed-gain, rail-to-rail operational amplifier in SOT23-5 package, featuring factory-trimmed internal resistors for 0.1% gain accuracy, ±17V input fault protection, 34µA supply current, and operation from +2.5V to +5.5V single supply. It serves as a precision signal-conditioning amplifier in low-side current-sense and photodiode preamp circuits.
For engineers reviewing the MAX4074CAEUK-T datasheet, MAX4074CAEUK-T pinout, MAX4074CAEUK-T application, or MAX4074CAEUK-T equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The MAX4074CAEUK-T integrates a rail-to-rail output op amp core with laser-trimmed on-chip feedback resistors (RF/RG), enabling fixed noninverting gains up to +101V/V or inverting gains down to -100V/V. Its decompensated architecture delivers up to 4MHz GBW at AV = +25V/V to +101V/V, while maintaining stability with capacitive loads ≤100pF without isolation resistors.
Input fault protection uses back-to-back SCR structures and diode clamps at both IN+ and IN− pins, limiting input fault current to <3.5mA under ±17V overvoltage. The inverting input connects directly to RG, resulting in a distinct input voltage range (±15V) versus the noninverting input (−0.15V to VCC − 1.2V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2.5V to +5.5V single supply - enables direct interface with 3.3V and 5V logic and sensors without level-shifting. |
| Supply Current | 34µA typical - supports multi-year battery life in portable equipment such as smart-card readers and remote controls. |
| Gain Accuracy | 0.1% (RF/RG) - eliminates external resistor matching and layout sensitivity, reducing BOM count and calibration effort. |
| Input Fault Protection | ±17V at either input - prevents latch-up or damage during sensor hot-plug, ESD transients, or power-rail faults. |
| Output Swing | Rail-to-rail into 1kΩ load - preserves full dynamic range across supply range, critical for low-voltage ADC interfacing. |
| GBW Product | Up to 4MHz (AV = +25V/V to +101V/V) - supports bandwidth-critical applications like infrared receiver baseband amplification. |
| Capacitive Load Stability | Stable up to 100pF - allows direct driving of ADC input capacitance or long PCB traces without added series resistance. |
Pinout & Package
SOT23-5 package: 2.9mm × 1.6mm × 1.1mm body, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier Output | Rail-to-rail output stage capable of sourcing/sinking ±22mA; drives 1kΩ load while maintaining DC accuracy. |

Use Value: Low 150nV/√Hz input voltage noise preserves SNR in weak-signal reception; stable pulse response avoids data corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4074AAEUK-T | Gain = +1.25V/V (noninverting); same package, supply, and fault protection. | Lower gain suitable for high-precision voltage monitoring where minimal signal scaling is needed. | Select when system requires unity-plus-margin gain without external resistors and maintains identical layout. |
| MAX4074DAEUK-T | Gain = +5V/V (noninverting); identical electrical specs except gain setting. | Balances bandwidth (90kHz −3dB) and gain for medium-level signal conditioning in sensor interfaces. | Choose for applications needing moderate gain with optimized GBW trade-off, e.g., thermistor or RTD front-ends. |
Compared with MAX4074CAEUK-T (+2.25V/V), MAX4074AAEUK-T offers lower gain for high-accuracy voltage monitoring, while MAX4074DAEUK-T provides higher gain for improved noise immunity in noisy environments-both retain identical fault protection, micropower consumption, and SOT23-5 footprint.

FAQ
What gain does the MAX4074CAEUK-T provide?
The MAX4074CAEUK-T provides a fixed noninverting gain of +2.25V/V, as indicated by the 'C' in the part number per Maxim's Gain Selector Guide. This gain is achieved via laser-trimmed internal RF/RG resistors with 0.1% accuracy, eliminating external components and layout sensitivity. The device operates in noninverting configuration by default, with IN+ as signal input and IN− connected internally to the feedback network.
Does the MAX4074CAEUK-T support single-supply operation?
Yes, the MAX4074CAEUK-T operates from a single +2.5V to +5.5V supply, with rail-to-rail output swing and input common-mode range extending to within 150mV of the negative rail (VEE). It is fully specified for single-supply use in portable equipment, including battery-powered smart-card readers and infrared receivers, and requires only a 0.1µF bypass capacitor on VCC.
What is the purpose of the N.C. pin in the MAX4074CAEUK-T SOT23-5 package?
The MAX4074CAEUK-T SOT23-5 package has no N.C. (no-connect) pin - all five pins (OUT, VEE, IN+, IN−, VCC) are functional and electrically connected. The confusion may arise from MAX4075 (8-pin SO/µMAX) or MAX4076 (SOT23-5 but open-loop), but the MAX4074CAEUK-T uses all five pins as defined in its pinout: OUT (1), VEE (2), IN+ (3), IN− (4), VCC (5).
How does the ±17V input fault protection work in the MAX4074CAEUK-T?
The MAX4074CAEUK-T implements ±17V input fault protection using back-to-back SCR structures and diode clamps at both IN+ and IN− pins. During overvoltage, current is limited to <3.5mA by internal 5kΩ (IN+) and RG (IN−) resistors, preventing latch-up or damage. This protection is active independently of supply state and is validated per Absolute Maximum Ratings - it does not affect normal operation within specified input voltage ranges.
Can the MAX4074CAEUK-T drive an ADC input directly?
Yes, the MAX4074CAEUK-T can drive most SAR and delta-sigma ADC inputs directly. Its rail-to-rail output swings within 5mV of VCC/VEE into 1kΩ, and it remains stable with capacitive loads up to 100pF - sufficient for typical ADC input capacitance (10–30pF). For ADCs with >100pF input capacitance, a small series isolation resistor (e.g., 10–50Ω) is recommended to ensure phase margin.
