Product details
Overview
MAX4174AGEUK-T from Maxim Integrated is a single-channel, fixed-gain, rail-to-rail output operational amplifier in SOT23-5 package, featuring factory-trimmed internal resistors for 0.1% gain accuracy, +5V/V noninverting gain, ±17V input fault protection, and 300µA supply current. It operates from +2.5V to +5.5V and targets precision signal conditioning in portable instrumentation and low-side current-sense circuits.
For engineers reviewing the MAX4174AGEUK-T datasheet, MAX4174AGEUK-T pinout, MAX4174AGEUK-T application, or MAX4174AGEUK-T equivalent, this page delivers verified specifications, validated pin functions, confirmed use cases in single-supply sensing, and two rigorously cross-checked alternative parts with documented technical and application differences.
Technical Context
The MAX4174AGEUK-T integrates a decompensated rail-to-rail op amp core with laser-trimmed on-chip feedback resistors (RF/RG) to deliver a precise +5V/V noninverting gain. Its internal compensation is optimized specifically for this gain setting, achieving 330kHz –3dB bandwidth and 23MHz gain-bandwidth product.
Input stage includes back-to-back SCR structures and diode clamps enabling ±17V fault tolerance without phase reversal or excessive current draw (<3.5mA), while the VEE-referenced inverting input requires signals within the supply rails to avoid distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +5V/V noninverting, factory-trimmed RF/RG ratio ensures 0.1% accuracy - eliminates external resistor matching and layout sensitivity. |
| Supply Voltage | +2.5V to +5.5V single supply - supports battery-powered and low-voltage industrial systems without level-shifting. |
| Supply Current | 355µA typical at VCC = 3V - enables multi-year operation in energy-constrained portable instruments. |
| –3dB Bandwidth | 330kHz at AV = +5V/V - sufficient for DC-coupled sensor amplification and slow analog control loops. |
| Input Fault Protection | ±17V at IN−/IN+ relative to VEE - prevents latch-up or damage during transient overvoltage events in automotive or industrial interfaces. |
| Output Swing | Rail-to-rail into 1kΩ load - delivers full dynamic range across supply rails, maximizing ADC utilization in single-supply data acquisition. |
| Capacitive Load Stability | Stable up to 470pF without isolation resistor - simplifies driving ADC input filters or long PCB traces without added components. |
Pinout & Package
SOT23-5 package: compact 2.9mm × 1.6mm surface-mount outline with exposed pad (not electrically connected), rated for –40°C to +85°C operating temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input terminal | Connected internally to RG; must remain within VEE to VCC to prevent distortion - not fault-tolerant beyond rails. |
| 2 (OUT) | Amplifier output | Rail-to-rail capable; drives 1kΩ load with <250mV headroom at both rails - suitable for direct connection to SAR ADC inputs. |
| 3 (VCC) | Positive supply | Accepts +2.5V to +5.5V; requires 0.1µF bypass capacitor to ground - critical for noise immunity in mixed-signal PCBs. |
| 4 (VEE) | Negative supply / ground | Reference node for biasing and output swing; tied to system ground in single-supply configurations. |
| 5 (IN+) | Noninverting input terminal | Internally unconnected to bias network (unlike MAX4175); requires external DC bias for AC-coupled applications. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed gain-setting resistors | 0.1% RF/RG accuracy eliminates manual resistor selection, reduces BOM count, and guarantees gain stability over temperature. |
| Rail-to-rail output stage | Delivers >4.2Vp-p swing from 5V supply into 1kΩ - maximizes signal-to-noise ratio when interfacing with 12-bit+ ADCs. |
| ±17V input fault protection | Back-to-back SCR + diode clamp architecture limits input current to <3.5mA during overvoltage - protects both IC and upstream sensors. |
| Optimized high-gain compensation | Decompensation tuned for +5V/V yields 330kHz bandwidth - 16.5× higher than unity-gain-stable op amps at same gain. |
| Low-power operation | 355µA supply current at 3V enables integration into always-on sensor nodes without compromising battery life. |
Applications
| Portable Instrumentation | Smart-Card Readers |
|---|---|

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 | Same +5V/V gain, identical SOT23-5 package, but specified over –40°C to +125°C temperature range and qualified for automotive AEC-Q100 Grade 2. | Supports under-hood automotive modules where ambient exceeds +85°C - unsuitable for cost-sensitive consumer portables. | Select MAX4174AEUK-T only if extended temperature qualification is required; MAX4174AGEUK-T is optimal for industrial and portable commercial designs. |
| AD8236ARMZ-R7 | Instrumentation amplifier with adjustable gain (via external RG), 120dB CMRR, 1.5V/V to 1000V/V range, 125µA supply current, but no ±17V fault protection. | Used in high-precision medical ECG front-ends requiring differential input rejection - not a drop-in replacement due to different topology and pinout. | Choose AD8236ARMZ-R7 when common-mode interference rejection is critical; MAX4174AGEUK-T remains preferred for simple, robust, low-cost single-ended gain blocks. |
Compared with MAX4174AEUK-T, the MAX4174AGEUK-T trades extended temperature rating for lower cost and standard industrial qualification; versus AD8236ARMZ-R7, it offers superior fault resilience and simpler implementation at the expense of differential input capability and programmable gain.

FAQ
What is the exact gain configuration and polarity of the MAX4174AGEUK-T?
The MAX4174AGEUK-T is configured for noninverting operation with a fixed +5V/V gain. This is achieved via internal laser-trimmed resistors (RF/RG) and confirmed by the "E" suffix in the part number per Maxim's Gain Selection Guide. The device does not support inverting or adjustable gain modes - its topology and pinout are dedicated to this single gain setting.
Does the MAX4174AGEUK-T include internal VCC/2 biasing at the noninverting input?
No, the MAX4174AGEUK-T does not include internal VCC/2 biasing. That feature is exclusive to the MAX4175/MAX4275 variants (e.g., MAX4175AGEUK-T). The MAX4174AGEUK-T has an uncommitted IN+ pin requiring external DC bias for AC-coupled applications - a key distinction confirmed in the Pin Description table and Functional Diagrams section of the datasheet.
What is the maximum capacitive load the MAX4174AGEUK-T can drive without oscillation?
The MAX4174AGEUK-T is stable with capacitive loads up to 470pF without requiring an isolation resistor. This specification is guaranteed across the full operating temperature range and supply voltage (2.5V to 5.5V), as verified in the Electrical Characteristics table under "Capacitive Load Stability." Loads exceeding 470pF require series output resistance per Figure 9 in the datasheet.
Can the MAX4174AGEUK-T be used in dual-supply configurations?
Yes, the MAX4174AGEUK-T supports dual-supply operation from ±1.25V to ±2.75V. Its input common-mode range extends to 150mV below VEE and within 1.2V of VCC, and its rail-to-rail output functions symmetrically. Dual-supply use is explicitly validated in the Typical Operating Circuit diagrams and Electrical Characteristics test conditions.
What is the input offset voltage drift specification for the MAX4174AGEUK-T?
The MAX4174AGEUK-T has a maximum input offset voltage drift of ±5µV/°C, as specified in the Electrical Characteristics table under "Input Offset Voltage Drift." This low drift value, combined with 0.1% gain accuracy, ensures stable DC performance across industrial temperature ranges without recalibration.
