Product details
Overview
MAX4174AJEUK-T from Maxim Integrated is a single-channel, noninverting fixed-gain amplifier with rail-to-rail output, 0.1% gain accuracy, +5V/V factory-set gain, and ±17V input fault protection. It operates from a +2.5V to +5.5V single supply, consumes only 355µA (typ), and delivers 23MHz GBW product at AV = +25V/V - optimized for precision signal conditioning in portable instrumentation and low-side current-sense applications.
For engineers reviewing the MAX4174AJEUK-T datasheet, MAX4174AJEUK-T pinout, MAX4174AJEUK-T application, or MAX4174AJEUK-T equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOT23-5 pinout, application-specific use value, and two confirmed alternative parts with documented functional differences.
Technical Context
The MAX4174AJEUK-T integrates a rail-to-rail op amp core with laser-trimmed internal feedback resistors (RF/RG) to deliver precise +5V/V noninverting gain without external components. Its decompensated architecture achieves 23MHz GBW at higher gains (+25V/V to +101V/V), while maintaining stability with up to 470pF capacitive loads and no isolation resistor.
Input stage includes back-to-back SCR structures and diode clamps enabling ±17V fault tolerance at IN−/IN+, with current limited to <3.5mA. The IN+ pin accepts signals from VEE to VCC, while IN− is constrained to rail-to-rail operation to avoid distortion - critical for accurate DC-coupled sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +5V/V noninverting, factory-trimmed RF/RG ratio ensures 0.1% accuracy - eliminates gain drift calibration in production. |
| Supply Voltage Range | +2.5V to +5.5V single supply - supports Li-ion battery-powered systems and 3.3V/5V logic domains without level shifting. |
| Supply Current | 355µA (typ at VCC = 3V) - enables always-on monitoring in ultra-low-power portable instruments. |
| Gain Bandwidth Product | 23MHz at AV = +25V/V - delivers usable bandwidth for 100kHz sensor signals even at high closed-loop gain. |
| Input Fault Protection | ±17V on IN−/IN+ relative to VEE - prevents latch-up or damage during hot-plug, ESD transients, or sensor overvoltage events. |
| Capacitive Load Stability | Stable with up to 470pF load - drives long PCB traces or ADC input capacitance without external isolation resistor. |
| Output Voltage Swing | Rail-to-rail into 1kΩ (VEE + 25mV to VCC − 25mV) - maximizes dynamic range for 12-bit+ data acquisition systems. |
Pinout & Package
SOT23-5 package: compact 2.9mm × 1.6mm footprint with exposed pad for thermal performance; rated for −40°C to +85°C industrial temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN− | Inverting input | Connected internally to RG; must remain within VEE to VCC to avoid distortion - not fault-protected beyond rails. |
| 2 - OUT | Amplifier output | Rail-to-rail capable; drives 1kΩ load with <25mV headroom - suitable for direct connection to SAR ADC inputs. |
| 3 - VCC | Positive supply | +2.5V to +5.5V input; requires 0.1µF bypass capacitor to ground - critical for noise immunity in mixed-signal layouts. |
| 4 - VEE | Negative supply / ground | Typically GND in single-supply designs; forms reference for internal bias and fault-protection circuitry. |
| 5 - IN+ | Noninverting input | DC-coupled input node; voltage range VEE to VCC - accepts full-rail sensor signals without clipping. |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed RF/RG network | 0.1% gain accuracy eliminates post-layout gain calibration and reduces BOM count by removing external resistors. |
| Rail-to-rail output stage | Delivers >4.9Vp-p swing from 5V supply into 100kΩ - preserves SNR in battery-operated data loggers. |
| ±17V input fault tolerance | Enables robust interfacing with industrial sensors or automotive subsystems without external TVS diodes. |
| 470pF capacitive load stability | Drives ADC input filters or long flex cables directly - avoids layout penalties from series isolation resistors. |
| 23MHz GBW at AV = +25V/V | Supports 100kHz closed-loop bandwidth at +100V/V gain - sufficient for fast current-sense loop response. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-gain amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4174AEUK-T | +1.25V/V noninverting gain; same SOT23-5 package, 0.1% gain accuracy, and ±17V fault protection. | Lower gain suits applications requiring minimal amplification before 12-bit ADCs - e.g., high-precision voltage monitoring. | Select when system gain budget allows lower amplification and wider input common-mode range is prioritized. |
| MAX4274AEUK-T | Dual-channel version with identical +1.25V/V gain per channel; shares same electrical specs and fault protection. | Reduces component count in multi-sensor systems (e.g., 3-phase current sensing) but increases quiescent current to 710µA. | Choose for space-constrained dual-signal paths where board area savings outweigh power trade-off. |
Compared with MAX4174AJEUK-T, the MAX4174AEUK-T offers lower gain for higher DC accuracy in voltage monitoring, while the MAX4274AEUK-T provides dual-channel integration at double the supply current - both retain identical fault protection and SOT23-5 compatibility.

FAQ
What is the exact gain setting of the MAX4174AJEUK-T?
The MAX4174AJEUK-T is configured for a noninverting fixed gain of +5V/V. This value is set by laser-trimmed internal RF/RG resistors and guaranteed to ±0.1% accuracy across −40°C to +85°C. The 'J' in the part number corresponds to the +5V/V gain code per Maxim's Gain Selection Guide - distinct from the +1.25V/V (A), +3V/V (C), or +10V/V (K) variants.
Does the MAX4174AJEUK-T include internal VCC/2 biasing?
No, the MAX4174AJEUK-T does not include internal VCC/2 biasing. That feature is exclusive to the MAX4175/MAX4275 variants. The MAX4174AJEUK-T is designed for DC-coupled applications where the user provides external biasing - its IN+ pin accepts full-rail input signals (VEE to VCC) without internal divider constraints.
Can the MAX4174AJEUK-T drive a 1000pF capacitive load?
The MAX4174AJEUK-T is specified stable up to 470pF without external compensation. Driving 1000pF requires an isolation resistor (e.g., 100Ω) in series with the output, as shown in Figure 9 of the datasheet. Without it, overshoot or ringing may occur - confirmed in typical operating characteristics (TOC10–TOC12) for CL = 1000pF.
What is the input voltage range for the IN− pin of the MAX4174AJEUK-T?
The IN− pin of the MAX4174AJEUK-T must be kept within the supply rails (VEE to VCC) to prevent distortion. Unlike IN+, it is not protected beyond the rails - exceeding this range forward-biases internal diodes and causes signal clipping. This constraint is explicitly defined in the Applications Information section and differs from open-loop op amps like the MAX4281.
Is the MAX4174AJEUK-T pin-compatible with other GainAmp devices in SOT23-5?
Yes, all MAX4174/MAX4175/MAX4274/MAX4275 SOT23-5 variants share identical pinout: Pin 1 = IN−, Pin 2 = OUT, Pin 3 = VCC, Pin 4 = VEE, Pin 5 = IN+. This allows drop-in replacement across gain options and bias configurations - confirmed in the Pin Configurations diagram and Pin Description table of the datasheet.
