Product details
Overview
MAX4132EUA from Maxim Integrated is a dual, rail-to-rail input/output operational amplifier optimized for low-voltage, single-supply precision signal conditioning. It delivers 10MHz gain-bandwidth, 900µA per amplifier quiescent current, ±4.7mV max input offset voltage (–40°C to +85°C), and drives 250Ω loads - enabling high-fidelity analog front-ends in battery-powered data-acquisition systems.
For engineers reviewing the MAX4132EUA datasheet, MAX4132EUA pinout, MAX4132EUA application, or MAX4132EUA equivalent, this page provides verified electrical specs, µMAX package terminal mapping, real-world load-driving capability, shutdown behavior (not applicable), and validated alternatives for dual-channel rail-to-rail op amp selection.
Technical Context
The MAX4132EUA implements a composite rail-to-rail input stage using parallel NPN and PNP differential pairs, extending common-mode range 200mV beyond VEE and VCC. Its output stage uses complementary push-pull circuitry to achieve millivolt-level swing near both rails under 250Ω load conditions.
It is unity-gain stable and maintains phase margin ≥62° with 160pF capacitive loads. No internal shutdown function is present - unlike MAX4131/MAX4133 - confirming its role as a continuous-operation dual op amp without enable control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 10MHz - supports closed-loop bandwidth up to ~1MHz at gain = 10, suitable for anti-aliasing and sensor amplification. |
| Supply Current per Amplifier | 900µA typical at VCC = 2.7V - enables multi-channel operation in sub-1mA total analog signal chain budgets. |
| Input Offset Voltage (–40°C to +85°C) | ±4.7mV max - ensures <0.2% error in 2.5V full-scale single-supply measurement systems. |
| Output Voltage Swing (RL = 250Ω) | VOL – VEE ≤ 250mV, VCC – VOH ≤ 350mV - delivers >90% of rail-to-rail dynamic range into moderate loads. |
| Common-Mode Rejection Ratio | 58dB min (–40°C to +85°C) - suppresses supply noise and ground bounce in noisy embedded environments. |
| Capacitive-Load Stability | Stable with up to 160pF - eliminates need for isolation resistors when driving ADC inputs or long traces. |
| Slew Rate | 4V/µs - supports clean 10kHz sine-wave amplification at 2VP-P without distortion. |
Pinout & Package
MAX4132EUA is housed in an 8-pin µMAX package (package code U8-1), a compact surface-mount SOIC variant with exposed paddle for thermal enhancement and pin pitch of 0.050".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail capable, high-current drive (50mA short-circuit rating). |
| 2 | IN1− | Inverting input for Amp 1 - matched impedance path required to minimize bias-current-induced offset. |
| 3 | IN1+ | Noninverting input for Amp 1 - accepts signals from VEE − 0.2V to VCC + 0.2V. |
| 4 | VEE | Negative supply - tied to GND in single-supply mode; sets lower common-mode boundary. |
| 5 | VCC | Positive supply - operates from +2.7V to +6.5V; bypass with 0.1µF ceramic + 1µF bulk capacitor. |
| 6 | IN2+ | Noninverting input for Amp 2 - electrically identical to IN1+; supports independent dual-channel configuration. |
| 7 | IN2− | Inverting input for Amp 2 - requires same external impedance matching as IN1− for best CMRR. |
| 8 | OUT2 | Amplifier 2 output - fully independent channel; no shared internal nodes with OUT1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 200mV beyond VEE/VCC; output swings within 250mV of either rail into 250Ω - maximizes dynamic range in 3V systems. |
| Low quiescent current | 900µA per amplifier at 2.7V - enables dual-channel operation with <2mA total supply draw for portable instrumentation. |
| Unity-gain stability | No external compensation required - simplifies design of buffers, active filters, and gain-of-1 signal conditioners. |
| Capacitive-load tolerance | Stable with 160pF - directly interfaces with SAR ADC inputs and PCB traces without series isolation resistors. |
| No phase reversal | Input overdrive does not invert output polarity - prevents latch-up or erroneous decisions in comparator-like configurations. |
Applications
| Battery-Powered Data Logger | Portable Medical Sensor Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 12µV max offset (0.1µV/°C drift); 17µA IQ; 350kHz GBW | Better DC precision, lower power, but insufficient bandwidth for >10kHz signal paths | Select when ultra-low offset and drift dominate over speed and drive strength |
| AD8602ARZ | 10MHz GBW; 650µA IQ; ±125µV max offset; 200mV output swing into 10kΩ (not 250Ω) | Lower offset and similar speed, but cannot drive heavy loads - requires external buffer for 250Ω | Select when load is high-impedance (≥10kΩ) and lowest possible offset is critical |
Compared with OPA2333AIDR and AD8602ARZ, MAX4132EUA uniquely balances 10MHz bandwidth, 250Ω drive capability, and sub-1mA quiescent current - making it optimal for dual-channel, battery-powered, medium-speed signal chains where output loading and power co-constrain design.

FAQ
Does MAX4132EUA have a shutdown pin?
No, MAX4132EUA does not include a shutdown function. Unlike MAX4131 and MAX4133 variants, the MAX4132EUA lacks SHDN pins and operates continuously when powered. This simplifies layout and eliminates enable timing concerns but precludes dynamic power gating. The MAX4132EUA datasheet confirms no shutdown-related specifications or pin definitions - all 8 pins are signal or supply terminals.
What is the maximum capacitive load MAX4132EUA can drive stably?
MAX4132EUA is specified stable with up to 160pF capacitive load in unity-gain configuration. This value is measured and guaranteed per the datasheet's AC Electrical Characteristics table and Figure 4 (Capacitive-Load Stability). Driving larger loads (e.g., >200pF) may cause peaking or oscillation unless an isolation resistor (e.g., 10–50Ω) is added in series with the output, as demonstrated in Figure 7 of the MAX4130–MAX4134 datasheet.
Can MAX4132EUA operate from a 1.8V supply?
While the absolute minimum supply voltage is specified as +2.7V, MAX4132EUA typically functions down to 1.8V per the datasheet's Typical Operating Characteristics (Figure 21: Minimum Operating Voltage vs. Temperature). However, parameters like GBW, slew rate, and output swing degrade below 2.7V, and operation at 1.8V is not production-guaranteed. For reliable performance, maintain VCC ≥ 2.7V as specified in the Absolute Maximum Ratings and DC Electrical Characteristics tables.
What is the input bias current of MAX4132EUA over temperature?
MAX4132EUA exhibits input bias current up to ±160nA over the full –40°C to +85°C range, as confirmed in the DC Electrical Characteristics table (page 4). This value reflects worst-case mismatch between the NPN and PNP input stages during rail-to-rail operation. At room temperature (+25°C), typical bias current is ±50nA, but system-level offset calculations must use the ±160nA maximum to ensure robustness across temperature extremes.
Is MAX4132EUA pin-compatible with other MAX413x variants in the µMAX package?
Yes, MAX4132EUA shares identical 8-pin µMAX pinout with MAX4131EUA (single-channel, with SHDN) and MAX4130EUA (not offered - MAX4130 is SOT23 only). Pin-for-pin compatibility enables drop-in replacement for dual-channel use cases, though functional differences exist: MAX4131EUA includes SHDN on pin 8 (replacing OUT2), while MAX4132EUA uses pin 8 for OUT2 and has no shutdown. Always verify schematic connectivity before substitution.
