Product details
Overview
MAX4175AGEUK-T from Maxim Integrated is a single-channel, noninverting fixed-gain amplifier with internal VCC/2 biasing, housed in a 5-pin SOT23 package. It delivers +5V/V gain with 0.1% accuracy, operates from +2.5V to +5.5V, consumes only 300µA, and features rail-to-rail output swing driving 1kΩ loads - ideal for low-power single-supply signal conditioning in portable instrumentation and smart-card readers.
For engineers reviewing the MAX4175AGEUK-T datasheet, MAX4175AGEUK-T pinout, MAX4175AGEUK-T application, or MAX4175AGEUK-T equivalent, this page provides 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 MAX4175AGEUK-T integrates a rail-to-rail op-amp core with laser-trimmed internal feedback resistors (RF/RG) and dual 150kΩ resistors forming a precision VCC/2 bias network at the noninverting input. Its gain is factory-set to +5V/V and decompensated for optimal bandwidth-achieving 330kHz −3dB bandwidth and 23MHz GBW product.
Input fault protection withstands ±17V at either terminal without phase reversal or excessive current draw (<3.5mA), enabled by back-to-back SCR structures and diode clamps with series limiting resistors. It remains stable driving capacitive loads up to 470pF without external isolation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +5V/V noninverting, fixed and laser-trimmed for 0.1% accuracy - eliminates external resistor matching and layout sensitivity |
| Supply Voltage Range | +2.5V to +5.5V single supply - supports Li-ion, USB, and low-voltage industrial rails without level-shifting |
| Supply Current | 300µA typical - enables battery operation >1 year in always-on sensor front-ends |
| −3dB Bandwidth | 330kHz at AV = +5V/V - sufficient for DC-coupled ECG, thermopile, and barcode scanner signal chains |
| Input Fault Tolerance | ±17V on IN+ or IN− - protects against ESD, hot-plug transients, and sensor cable faults in field-deployed equipment |
| Capacitive Load Stability | Stable up to 470pF - drives ADC input filters, long PCB traces, or coaxial cables without oscillation or compensation redesign |
| Output Swing | Rail-to-rail into 1kΩ load - delivers full dynamic range across 0–5V systems, maximizing SNR in 12-bit+ data acquisition |
Pinout & Package
Package: 5-pin SOT23 (SC-70), 1.6mm × 1.6mm footprint, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | Connects directly to internal RG resistor; voltage must remain within supply rails to avoid distortion or clipping |
| 2 (OUT) | Amplifier output | Rail-to-rail capable; drives 1kΩ loads with <250mV headroom at both rails; stable with ≤470pF capacitive load |
| 3 (VCC) | Positive supply | Accepts +2.5V to +5.5V; requires 0.1µF bypass capacitor to ground placed adjacent to pin |
| 4 (VEE) | Negative supply / ground | Connected to system ground in single-supply operation; forms reference for internal VCC/2 bias network |
| 5 (IN+) | Noninverting input | Internally biased to VCC/2 via dual 150kΩ resistors - eliminates external bias components in AC-coupled designs |
Key Features
| Feature | Design Value |
|---|---|
| VCC/2 internal bias network | Dual 150kΩ resistors provide precise mid-supply reference at IN+, enabling AC-coupled single-supply amplification without external components |
| 0.1% gain accuracy | Laser-trimmed RF/RG ratio ensures production-grade gain tolerance - reduces calibration steps in production test |
| ±17V input fault protection | SCR-based clamping limits input current to <3.5mA during overvoltage events - enhances reliability in unshielded sensor interfaces |
| Rail-to-rail output stage | Delivers full-scale swing from VEE to VCC into 1kΩ - preserves signal fidelity in low-voltage microcontroller ADC front-ends |
| 470pF capacitive load stability | No external isolation resistor required - simplifies layout and avoids phase-margin trade-offs in filter-driven applications |
Applications
| Portable Instrumentation | Smart-Card Readers |
|---|---|
Use Scenario: Amplifying low-level analog signals from thermistors, RTDs, or photodiodes in handheld multimeters and environmental sensors.

Use Scenario: Measuring shunt voltage in battery-powered motor controllers or power tool battery packs. IC Role / Device Role / Timing Role: Fixed +5V/V gain amplifier referenced to system ground (VEE), scaling mV-level shunt drops to measurable 0–2.5V range. Use Value: 0.1% gain accuracy enables ±0.5% current measurement; 300µA quiescent current extends runtime in always-monitoring configurations. |
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 SOT23-5 package and +5V/V gain, but lacks internal VCC/2 bias - requires external bias network for single-supply use | Suitable for dual-supply or DC-coupled single-supply designs where IN+ bias is externally controlled | Select when board already includes precision biasing or when tighter IN+ common-mode control is required |
| MAX4275AESA+ | Same +5V/V gain and VCC/2 bias, but in 8-pin SO package - larger footprint, higher thermal mass, and different pinout | Better suited for high-reliability industrial modules requiring SOIC hand-soldering or thermal cycling margin | Choose when SOT23 assembly constraints prevent use or when SOIC rework capability is mandatory |
Compared with MAX4174AEUK-T, the MAX4175AGEUK-T saves two external bias resistors and associated layout space; compared with MAX4275AESA+, it offers identical functionality in a 40% smaller footprint and lower profile - critical for ultra-thin portable devices.

FAQ
What is the exact gain configuration and tolerance of the MAX4175AGEUK-T?
The MAX4175AGEUK-T is a noninverting fixed-gain amplifier with a nominal gain of +5V/V. Its gain accuracy is specified at 0.1% due to factory laser trimming of internal RF/RG resistors. This tolerance is guaranteed across the operating temperature range of −40°C to +85°C and applies directly to the MAX4175AGEUK-T without requiring external calibration or trimming.
Does the MAX4175AGEUK-T require external biasing components for single-supply operation?
No. The MAX4175AGEUK-T integrates dual 150kΩ resistors that form an internal VCC/2 bias network at the IN+ pin. This eliminates the need for external resistors or capacitors to establish a mid-supply reference, simplifying design and reducing component count - a key advantage over the MAX4174AEUK-T, which lacks this feature.
What is the maximum capacitive load the MAX4175AGEUK-T can drive without instability?
The MAX4175AGEUK-T is characterized and guaranteed stable with capacitive loads up to 470pF when driving a 100kΩ load, per the datasheet's "Capacitive Load Stability" specification. No external isolation resistor is required within this limit, making it suitable for direct connection to ADC input filters, long traces, or shielded cables without compensation redesign.
How does the ±17V input fault protection work in the MAX4175AGEUK-T?
The MAX4175AGEUK-T implements ±17V input fault protection using back-to-back SCR structures at both IN+ and IN− pins, combined with diode clamps to VCC and VEE. Input current is limited to <3.5mA during overvoltage events, preventing damage to the internal op-amp core and protecting upstream signal sources - a feature confirmed in the Absolute Maximum Ratings and Applications Information sections of the MAX4175AGEUK-T datasheet.
Is the MAX4175AGEUK-T pin-compatible with other GainAmp devices like the MAX4174AEUK-T?
Yes - the MAX4175AGEUK-T shares identical pinout (SOT23-5), supply connections, and output structure with the MAX4174AEUK-T. However, the IN+ pin function differs: MAX4175AGEUK-T has internal VCC/2 bias, while MAX4174AEUK-T leaves IN+ uncommitted. Swapping them requires verifying biasing topology; they are not drop-in replacements without schematic review.
