Product details
Overview
MAX417CPA from Maxim Integrated is a quad, single-supply operational amplifier optimized for ultra-low-power sensor signal conditioning in battery-powered instrumentation. It features 1.2µA maximum supply current per amplifier, 150kHz gain-bandwidth product, and rail-to-rail output swing with ±0.5V input common-mode range extending to VEE. It operates from +2.7V to +11V over 0°C to +70°C.
For engineers reviewing the MAX417CPA datasheet, MAX417CPA pinout, MAX417CPA application, or MAX417CPA equivalent, key selection criteria include its quad-channel configuration in 8-pin DIP, guaranteed 1.2µA max ICC per op-amp at +25°C, rail-to-rail output drive into 10kΩ, and compatibility with single-supply industrial sensor front-ends requiring minimal quiescent power.
Technical Context
The MAX417CPA integrates four independent precision op-amps on a single die, each with matched DC characteristics and shared supply pins. Its input stage uses p-channel JFET inputs to achieve sub-1pA bias current and high input impedance (>1012Ω), enabling direct interfacing with high-impedance sensors like piezoelectric elements and pH electrodes.
Internal compensation ensures unity-gain stability across the full temperature and supply range. The rail-to-rail output stage delivers >98% of VCC–VEE swing into 10kΩ load, while maintaining 150kHz GBW and 0.15V/µs slew rate-critical for low-frequency precision amplification without phase error accumulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad, ultra-low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPW | Higher 550µA supply current per amp; 6.4MHz GBW; rail-to-rail input/output | Better AC performance but 460× higher quiescent current limits battery life | Select only when bandwidth >100kHz is required and power budget permits |
| LP324N | 45µA supply current per amp; 100kHz GBW; no rail-to-rail output | Lower power than TLV2464 but still 37× higher than MAX417CPA; limited output swing | Acceptable for cost-sensitive, non-battery applications where 1.2µA is not mandatory |
Compared with TLV2464IPW and LP324N, the MAX417CPA uniquely delivers sub-1.5µA per-amplifier operation with rail-to-rail output-enabling multi-channel, long-life sensor nodes where every nanoamp affects field deployment duration.

FAQ
What is the operating supply voltage range for the MAX417CPA?
The MAX417CPA operates from a single supply of +2.7V to +11V. It is specified for full DC performance across this range at temperatures from 0°C to +70°C. Operation outside these limits may result in degraded parameters or undefined behavior. The MAX417CPA does not require dual supplies and is designed explicitly for single-rail systems where ground serves as the negative reference.
Does the MAX417CPA support rail-to-rail input operation?
No, the MAX417CPA does not support rail-to-rail input. Its input common-mode voltage range extends from VEE to VCC – 1.2V. This allows the noninverting input to operate down to ground in single-supply configurations but excludes the positive rail. The MAX417CPA does provide rail-to-rail output swing, delivering within 20mV of both supply rails under typical load conditions.
Can the MAX417CPA be used in place of the MAX417CSA?
Yes, the MAX417CPA and MAX417CSA share identical electrical specifications and functional pinout, differing only in package: 8-pin plastic DIP versus 8-pin SO. PCB layout must be adapted for through-hole versus surface-mount mounting. Thermal and parasitic differences may affect high-frequency stability margins, so layout review is recommended when substituting MAX417CPA for MAX417CSA in existing SO-based designs.
What is the maximum guaranteed supply current per amplifier in the MAX417CPA?
The MAX417CPA guarantees a maximum supply current of 1.2µA per amplifier at +25°C and nominal supply voltage. This value is tested and specified across the commercial temperature range (0°C to +70°C). Total device current is approximately 4.8µA for all four amplifiers active, making it among the lowest-power quad op-amps available for battery-critical applications.
Is the MAX417CPA pin-compatible with other devices in the MAX406–MAX419 family?
Within the same package type and channel count, yes-the MAX417CPA shares identical pinout with MAX406CPA, MAX407CPA, and MAX409CPA (all 8-pin DIP quad variants). However, internal gain-bandwidth, input bias current, and offset voltage differ across the family. Substitution requires verification of AC/DC performance requirements; MAX417CPA is optimized for lowest ICC, while others trade current for speed or precision.
