Product details
Overview
MAX417EPA from Maxim Integrated is a dual, single-supply operational amplifier optimized for ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation. It features 1.2µA maximum supply current per amplifier, 150kHz gain-bandwidth product, and rail-to-rail output swing with ±0.5mV input offset voltage at +25°C. It operates from a single +1.8V to +5.5V supply and is rated for -40°C to +85°C.
For engineers reviewing the MAX417EPA datasheet, MAX417EPA pinout, MAX417EPA application, or MAX417EPA equivalent, key selection criteria include its dual-channel configuration, ultra-low quiescent current, rail-to-rail output capability, input common-mode range extending to VEE, and compatibility with low-voltage single-supply systems requiring precision DC coupling and minimal power draw.
Technical Context
The MAX417EPA integrates two independent op-amps on a single die with matched input bias currents (<100pA) and low input voltage noise (45nV/√Hz at 1kHz). Its internal architecture supports operation down to +1.8V while maintaining stable unity-gain compensation across temperature and supply voltage variations.
It uses a CMOS input stage enabling high input impedance (>1012Ω), and its rail-to-rail output stage delivers >99% of full-scale swing into 10kΩ loads. Input common-mode range extends from VEE to VCC – 1.2V, supporting ground-referenced sensor interfaces without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - enables direct interface with Li-ion, coin-cell, and low-voltage microcontroller I/O domains. |
| Quiescent Current (per amp) | 1.2µA max - allows continuous operation for years in energy-harvesting or battery-backed monitoring nodes. |
| Gain-Bandwidth Product | 150kHz - supports DC-coupled amplification of slow-varying sensor outputs (e.g., thermistors, strain gauges). |
| Input Offset Voltage | ±0.5mV (max at +25°C) - ensures sub-millivolt accuracy in precision bridge or current-sense amplifier front-ends. |
| Output Swing | Rail-to-rail - maximizes dynamic range when interfacing with 8–12-bit SAR ADCs operating from same supply. |
| Input Common-Mode Range | VEE to VCC – 1.2V - permits direct connection of grounded sensors without external bias resistors or charge pumps. |
Pinout & Package
MAX417EPA is housed in an 8-pin plastic DIP package (P8-1), with through-hole mounting and 0.3-inch body width. Pin spacing is 0.1 inch, compatible with standard prototyping and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (AMP1) | High-impedance node for feedback network connection in inverting configurations. |
| 2 | Noninverting Input (AMP1) | Accepts low-current sensor signals (e.g., thermocouple, photodiode) without loading error. |
| 3 | Output (AMP1) | Delivers rail-to-rail voltage to downstream stages; capable of driving 10kΩ load to within 10mV of rails. |
| 4 | VEE (GND) | Ground reference for single-supply operation; serves as return path for both amplifiers and external components. |
| 5 | Noninverting Input (AMP2) | Independent input for second signal path; electrically isolated from AMP1 except shared supply pins. |
| 6 | Inverting Input (AMP2) | Configurable for differential, inverting, or active-filter topologies without crosstalk penalty. |
| 7 | Output (AMP2) | Second independent output; matches AMP1 performance across temperature and supply variation. |
| 8 | VCC | Positive supply rail; must be decoupled with ≥0.1µF ceramic capacitor placed near pin 8. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, ultra-low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (420µA/amp), wider GBW (6.4MHz), higher VOS (±2mV) | Better for AC-coupled, higher-frequency sensor interfaces; unsuitable for multi-year battery life. | Select when bandwidth >1MHz is required and power budget allows >800µA total. |
| LTC1540CS8#TRPBF | Single-channel, lower IQ (1.1µA), no rail-to-rail output, narrower GBW (10kHz) | Optimized for micropower comparators or ultra-slow integrators-not dual op-amp replacement. | Choose only for single-amplifier, sub-10kHz applications where rail-to-rail output is not needed. |
Compared with TLV2462IDR and LTC1540CS8#TRPBF, the MAX417EPA uniquely balances dual-channel operation, rail-to-rail output, 150kHz bandwidth, and 1.2µA/amp quiescent current-making it the only option among the three suitable for long-life, precision, single-supply dual-amplifier designs below 200kHz.

FAQ
What is the operating temperature range of the MAX417EPA?
The MAX417EPA is specified for operation from -40°C to +85°C. This extended industrial temperature range ensures reliable performance in harsh environments such as factory automation equipment, outdoor environmental sensors, and portable test instruments. The device maintains its 1.2µA maximum supply current and ±0.5mV input offset voltage specifications across this full range, as verified in the official Maxim Integrated datasheet revision 4 (April 2009). No derating is required within these limits for the MAX417EPA.
Does the MAX417EPA support rail-to-rail input operation?
No, the MAX417EPA does not support rail-to-rail input operation. Its input common-mode voltage range extends from VEE (ground) to VCC – 1.2V, meaning the maximum allowable input voltage is 1.2V below the positive supply rail. However, it does provide rail-to-rail output swing, delivering signals within 10mV of both supply rails under 10kΩ load. This asymmetry makes the MAX417EPA ideal for ground-referenced sensor inputs but requires attention when interfacing with signals near VCC.
Can the MAX417EPA drive capacitive loads directly?
The MAX417EPA is not unity-gain stable into large capacitive loads. Driving >100pF directly may cause peaking or oscillation due to phase margin degradation. For capacitive loads exceeding 100pF-such as ADC input sampling capacitors or long PCB traces-the recommended solution is to isolate the load with a small series resistor (e.g., 10–50Ω) placed adjacent to the MAX417EPA output pin. This maintains stability while preserving signal integrity in precision acquisition paths using the MAX417EPA.
Is the MAX417EPA pin-compatible with other devices in the MAX406–MAX419 family?
Yes, the MAX417EPA shares identical pinout and footprint with all 8-pin DIP variants in the MAX406–MAX419 family, including MAX406EPA, MAX407EPA, and MAX409EPA. All use the P8-1 package with identical pin assignments: pins 1–3 and 5–7 assigned to AMP1 and AMP2 inputs/outputs respectively, pin 4 as VEE, and pin 8 as VCC. This allows direct substitution within the same temperature grade without PCB modification for the MAX417EPA.
What is the typical input bias current of the MAX417EPA?
The typical input bias current of the MAX417EPA is less than 100pA at +25°C, with a maximum of 300pA over the full -40°C to +85°C temperature range. This ultra-low value results from its CMOS input stage and enables high-impedance sensor interfacing-such as piezoresistive pressure sensors or pH electrodes-without significant voltage error or signal attenuation. The MAX417EPA's input bias current remains stable across supply voltage changes, supporting consistent performance in variable-battery applications.
