Product details
Overview
The MAX4175BJEUK-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 accuracy of ±0.1%, operates from +2.5V to +5.5V supply, consumes only 355µA (typ), and features rail-to-rail output swing driving 1kΩ while maintaining DC precision - ideal for low-power single-supply signal conditioning in portable instrumentation.
For engineers reviewing the MAX4175BJEUK-T datasheet, MAX4175BJEUK-T pinout, MAX4175BJEUK-T application, or MAX4175BJEUK-T equivalent, key selection criteria include its factory-trimmed gain accuracy, integrated mid-supply bias eliminating external resistors, ±17V input fault protection, 23MHz GBW product at high gains, and stability with up to 470pF capacitive loads without isolation resistors.
Technical Context
This device integrates a rail-to-rail output op-amp core with laser-trimmed internal feedback resistors (RF/RG) and dual 150kΩ resistors forming a VCC/2 bias network at the noninverting input. Its compensation is optimized for +5V/V closed-loop gain, delivering 330kHz –3dB bandwidth and 23MHz gain-bandwidth product.
The input stage includes back-to-back SCR structures and diode clamps enabling ±17V fault tolerance at IN–/IN+, with current limited to <3.5mA per pin. The IN+ common-mode range is fixed at VCC/2 ±0.25V, while IN– accepts signals from VEE to VCC, supporting wide-input-range AC-coupled sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +5V/V noninverting, factory-trimmed for ±0.1% accuracy - eliminates external resistor matching and layout sensitivity. |
| Supply Voltage | +2.5V to +5.5V single supply - supports Li-ion battery and 3.3V/5V system rails without level-shifting. |
| Supply Current | 355µA typical at VCC = 3V - enables always-on operation in power-constrained portable instruments. |
| GBW Product | 23MHz at AV = +25V/V to +101V/V - provides usable bandwidth even at high closed-loop gains. |
| Input Fault Protection | ±17V on IN–/IN+ relative to VEE - prevents latch-up or damage during sensor overvoltage transients. |
| Capacitive Load Stability | Stable with ≤470pF load - drives ADC input filters or long traces without external isolation resistors. |
| Output Swing | Rail-to-rail into 1kΩ - delivers full dynamic range across VEE to VCC for maximum SNR in 12-bit+ systems. |
Pinout & Package
MAX4175BJEUK-T is packaged in a 5-pin SOT23-5 surface-mount package with exposed pad (JEDEC MO-178AA), footprint-compatible with industry-standard SOT23 layouts and reflow-process ready.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–) | Inverting input | Connects internally to RG; accepts signals from VEE to VCC; requires no external feedback components. |
| 2 (OUT) | Amplifier output | Rail-to-rail voltage source capable of sourcing/sinking >1mA into 1kΩ load with <250mV headroom. |
| 3 (VCC) | Positive supply | +2.5V to +5.5V input; bypass with 0.1µF capacitor to ground near pin for noise immunity. |
| 4 (VEE) | Negative supply / ground | Reference node for bias and output swing; must be connected to system ground in single-supply use. |
| 5 (IN+) | Noninverting input | Internally biased to VCC/2 via dual 150kΩ resistors - eliminates external bias network for AC-coupled inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated VCC/2 bias network | Two matched 150kΩ resistors eliminate external bias components and reduce PCB area by ≥30% in AC-coupled front-ends. |
| 0.1% gain accuracy | Laser-trimmed RF/RG ratio ensures consistent gain across temperature and unit-to-unit variation - critical for calibrated measurement paths. |
| ±17V input fault tolerance | SCR-based protection allows direct connection to industrial sensors or automotive lines without external TVS or series resistors. |
| Rail-to-rail output with 1kΩ drive | Maintains <0.5% linearity error at full-scale swing into 1kΩ - supports direct interface to SAR ADC reference buffers. |
| 470pF capacitive load stability | Enables direct driving of anti-aliasing filters or long PCB traces without adding phase-margin degradation or overshoot. |

FAQ
What is the exact gain configuration of the MAX4175BJEUK-T?
The MAX4175BJEUK-T is a noninverting fixed-gain amplifier with a nominal gain of +5V/V. This value is achieved using factory-laser-trimmed internal resistors (RF/RG) and is specified with ±0.1% accuracy across temperature. The 'B' suffix in the part number explicitly denotes the +5V/V gain variant per Maxim's Gain Selection Guide.
Does the MAX4175BJEUK-T require external biasing components?
No. The MAX4175BJEUK-T integrates dual 150kΩ resistors that form an internal VCC/2 bias network at the IN+ pin. This eliminates the need for external resistors in AC-coupled applications, simplifying layout and improving thermal tracking versus discrete bias networks.
Can the MAX4175BJEUK-T operate from a 3.3V supply?
Yes. The MAX4175BJEUK-T is fully specified for operation from +2.5V to +5.5V single supply. At VCC = 3.3V, it maintains rail-to-rail output swing, 355µA typical supply current, and retains ±0.1% gain accuracy - making it compatible with standard 3.3V logic and power domains.
What is the maximum capacitive load the MAX4175BJEUK-T can drive stably?
The MAX4175BJEUK-T is stable with capacitive loads up to 470pF without requiring external isolation resistors. This specification is verified per Maxim's Typical Operating Characteristics (TOC11–TOC12) and applies directly to the MAX4175BJEUK-T variant under standard operating conditions.
How does the ±17V input fault protection work on the MAX4175BJEUK-T?
The MAX4175BJEUK-T implements ±17V fault protection on both IN– and IN+ pins using back-to-back SCR structures and diode clamps referenced to VCC and VEE. During overvoltage, current is limited to <3.5mA per pin by internal 5kΩ (IN+) and RG (IN–) resistors - protecting both the IC and upstream signal sources.
