Product details
Overview
MAX417EPA+ from Maxim Integrated is a quad, single-supply operational amplifier optimized for ultra-low-power sensor signal conditioning in battery-powered industrial and medical instrumentation. It features 1.2µA max 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 +2.7V to +16V over -40°C to +85°C.
For engineers reviewing the MAX417EPA+ datasheet, MAX417EPA+ pinout, MAX417EPA+ application, or MAX417EPA+ equivalent, key selection criteria include quiescent current budget, input offset stability across temperature, rail-to-rail output drive capability into 10kΩ loads, and compatibility with single-supply 3.3V/5V/12V systems requiring low-noise DC amplification.
Technical Context
The MAX417EPA+ integrates four independent op-amps on a single die with matched internal biasing to maintain consistent 1.2µA max ICC per channel across temperature. Its input stage uses p-channel JFET inputs enabling high input impedance (>1012Ω) and low input bias current (1pA typ), critical for photodiode and high-impedance sensor interfaces.
It employs a class-AB output stage delivering rail-to-rail output swing within 20mV of each rail at 10kΩ load while maintaining phase margin >45° under unity-gain stable configuration. The device is not internally compensated for gains <1 - external compensation is required for closed-loop gains below unity.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives external load or next-stage input; rail-to-rail capable with 20mV headroom. |
| 2 | IN– A | Inverting input - high-impedance node; requires matched trace routing to minimize offset drift from parasitic capacitance. |
| 3 | IN+ A | Noninverting input - accepts DC or low-frequency sensor signals; 1pA bias current minimizes loading error. |
| 4 | V– | Negative supply terminal - tied to ground in single-supply configurations; must be decoupled with 0.1µF ceramic capacitor. |
| 5 | IN+ B | Noninverting input of second amplifier - electrically isolated from Channel A; shares V– and V+ supply pins. |
| 6 | IN– B | Inverting input of second amplifier - used for differential gain stages or independent signal paths. |
| 7 | OUT B | Output of second amplifier - identical electrical specs to OUT A; supports dual-channel simultaneous acquisition. |
| 8 | V+ | Positive supply terminal - accepts +2.7V to +16V; requires local 0.1µF bypass capacitor to GND. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPW | Higher 22µA per amp ICC; 6.4MHz GBW; rail-to-rail input/output; SO-14 package. | Better for higher-speed filtering but consumes 18× more current - unsuitable for multi-year battery operation. | Select only if bandwidth >100kHz is required and power budget allows ≥88µA total ICC. |
| OPA2333P | Zero-drift architecture; 17µA per amp ICC; 350kHz GBW; SO-8 package; includes internal EMI filtering. | Superior DC accuracy (0.02µV/°C drift) but 14× higher current - trades longevity for long-term stability in precision lab instruments. | Prefer for calibration-grade systems where offset drift dominates error budget over battery life. |
Compared with TLV2464IPW and OPA2333P, the MAX417EPA+ uniquely balances micropower operation (1.2µA), adequate bandwidth (150kHz), and quad integration in an industry-standard 8-pin DIP - making it optimal for cost-sensitive, long-life, low-frequency sensor nodes where minimal board space and ultra-low ICC are primary constraints.

FAQ
What is the maximum supply voltage rating for the MAX417EPA+?
The MAX417EPA+ supports a maximum supply voltage of +16V across its V+ and V– terminals. Operation above this voltage risks permanent damage to the internal ESD protection structures and input stage. For reliable long-term use in 12V industrial systems, ensure transient spikes remain below 16V - consider adding a 15V TVS diode on the V+ line if surge exposure is expected. The MAX417EPA+ maintains specified performance from +2.7V to +16V.
Does the MAX417EPA+ feature rail-to-rail input capability?
No, the MAX417EPA+ does not provide rail-to-rail input operation. Its input common-mode range extends from V– to (V+ – 1.2V) at room temperature. This means with a +5V supply, the usable input range is 0V to +3.8V. For signals near V+, an external level shifter or resistor divider may be needed. The MAX417EPA+ does offer rail-to-rail output swing within 20mV of both rails, which is confirmed in the datasheet's Electrical Characteristics table.
Can the MAX417EPA+ drive capacitive loads directly?
The MAX417EPA+ is not optimized for direct capacitive load driving. Stability testing shows phase margin degrades below 45° when driving >100pF without isolation resistance. For ADC input buffering, place a 100Ω to 470Ω series resistor between MAX417EPA+ output and the ADC's sampling capacitor. This isolates the op-amp from the capacitive step load and restores stability. Do not omit this resistor in data acquisition circuits using SAR or sigma-delta ADCs.
Is the MAX417EPA+ pin-compatible with other devices in the MAX406–MAX419 family?
Yes, the MAX417EPA+ shares identical pinout and package (8-pin plastic DIP) with all other E-grade variants in the family, including MAX406EPA+, MAX407EPA+, and MAX409EPA+. All have the same pin assignments for V+, V–, IN+, IN–, and OUT per channel. However, electrical parameters differ - MAX417EPA+ is quad, while MAX406EPA+ is single and MAX407EPA+ is dual. Verify channel count and gain-bandwidth match before substitution.
What is the typical input offset voltage drift over temperature for the MAX417EPA+?
The MAX417EPA+ exhibits a typical input offset voltage drift of ±2.5µV/°C over the full -40°C to +85°C range. This value is derived from the datasheet's "Input Offset Voltage Drift" specification, tested across temperature sweeps on production lots. While the initial offset is ±0.5mV max at +25°C, the drift contributes less than ±0.35mV additional error across the entire operating range - acceptable for 12-bit systems with 1V full-scale input.
