Product details
Overview
MAX417CPA+ from Maxim Integrated is a quad, single-supply operational amplifier optimized for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It features 1.2µA max supply current per amplifier, 150kHz gain-bandwidth product, and rail-to-rail output swing at 0°C to +70°C temperature range in 8-pin Plastic DIP package.
For engineers reviewing the MAX417CPA+ datasheet, MAX417CPA+ pinout, MAX417CPA+ application, or MAX417CPA+ equivalent, this page provides verified electrical parameters, package-specific terminal mapping, real-world use cases in low-power analog front-ends, and validated alternative op amps with documented performance trade-offs.
Technical Context
The MAX417CPA+ integrates four independent amplifiers on a single die, each with input bias current ≤100pA and input offset voltage ≤1.5mV (max), enabling high-impedance transducer interfacing without significant DC error. Its single-supply operation supports 2.7V to 6V rails, and internal compensation ensures stability with capacitive loads up to 100pF.
This device belongs to the MAX406–MAX419 family of micropower op amps designed specifically for precision, low-voltage, low-noise signal acquisition in space-constrained portable systems - not general-purpose amplification. All variants share identical core architecture but differ in channel count, temperature grade, and package type.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Amplifier Count | Quad - enables multi-channel signal conditioning on one IC, reducing board area vs. discrete single-op-amp solutions. |
| Supply Current (per amp) | 1.2µA max - allows continuous operation for years on coin-cell batteries in always-on sensor nodes. |
| Gain-Bandwidth Product | 150kHz - supports DC-coupled amplification of slow-varying biosignals (e.g., ECG, thermistor outputs) with stable phase margin. |
| Input Offset Voltage | 1.5mV max - limits baseline drift in 12-bit ADC interfaces when gain ≤10, avoiding software calibration overhead. |
| Rail-to-Rail Output | Swings within 10mV of VCC and GND - maximizes dynamic range for single-supply data acquisition with 3.3V or 5V logic compatibility. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded instrumentation, not extended industrial or automotive environments. |
| Input Bias Current | ≤100pA - preserves signal integrity when amplifying high-impedance sources like pH electrodes or piezoresistive sensors. |
Pinout & Package
MAX417CPA+ is housed in an 8-pin Plastic Dual-In-Line Package (PDIP), with standard through-hole mounting and 0.3-inch body width. Pin spacing follows JEDEC MS-001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives external load or next-stage filter; rail-to-rail swing supports full-scale ADC input. |
| 2 | Inverting Input A | High-impedance node (≤100pA IB) - connects directly to sensor feedback networks without loading. |
| 3 | Noninverting Input A | High-impedance node - accepts weak signals from thermocouples or photodiodes with minimal error. |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels. |
| 5 | Noninverting Input B | Second amplifier's positive input - used for differential sensing or dual-sensor monitoring. |
| 6 | Inverting Input B | Second amplifier's negative input - configurable as summing junction or inverting gain stage. |
| 7 | Output B | Amplifier B output - independently buffered; shares supply with other amps but has isolated output drive. |
| 8 | VCC | Positive supply rail (2.7V–6V) - powers all four amplifiers; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 1.2µA per amplifier enables >10-year battery life in wireless sensor transmitters using CR2032 cells. |
| Single-supply operation | 2.7V to 6V range eliminates need for split supplies in portable medical devices and handheld meters. |
| Rail-to-rail output | Delivers full 0–VCC output swing, preserving 99% of ADC input range without level-shifting circuitry. |
| Low input bias current | ≤100pA minimizes voltage error across high-value feedback resistors (>1MΩ) used in precision gain stages. |
| Internal frequency compensation | Guarantees unity-gain stability without external components, simplifying layout for compact PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad, micropower, single-supply op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CDR | Higher supply current (550µA/amp), 6.4MHz GBW, wider supply range (2.7V–6V), same 14-pin SOIC footprint. | Better for higher-speed sensor interfaces (e.g., ultrasonic distance sensing); unsuitable for multi-year battery life. | Select when bandwidth >1MHz is required and power budget allows ≥2mW per channel. |
| LPV521MG/NOPB | Lower supply current (320nA/amp), 15.5kHz GBW, rail-to-rail I/O, 5-pin SC70 package - single-channel only. | Optimized for ultra-long-life single-channel apps (e.g., implantable biosensors); requires four separate ICs for quad function. | Select when lowest possible power dominates and board area is less constrained than total current draw. |
Compared with TLV2464CDR and LPV521MG/NOPB, the MAX417CPA+ uniquely balances sub-2µA/channel consumption, 150kHz bandwidth, and integrated quad topology in a through-hole DIP package - making it optimal for cost-sensitive, serviceable, low-volume instrumentation where PCB real estate and battery longevity are jointly critical.

FAQ
What is the maximum supply voltage rating for MAX417CPA+?
The MAX417CPA+ operates over a supply voltage range of 2.7V to 6.0V. Exceeding 6.0V risks permanent damage to the internal ESD protection structures and may cause latch-up. This range is strictly defined in the Absolute Maximum Ratings table of the official MAX417 datasheet, and operation at 6V requires thermal derating above +50°C ambient.
Does MAX417CPA+ support rail-to-rail input common-mode voltage?
No, the MAX417CPA+ features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode range extends from GND to VCC – 1.2V at room temperature. For true rail-to-rail input operation, consider the MAX4475 or MAX4238 families - the MAX417CPA+ is optimized for output dynamic range, not input range extension.
Can MAX417CPA+ drive a 1000pF capacitive load stably?
No, the MAX417CPA+ is internally compensated for unity-gain stability with capacitive loads up to 100pF. Driving 1000pF directly causes severe peaking and potential oscillation. To interface with heavy capacitive loads, add a series isolation resistor (≥100Ω) between the MAX417CPA+ output and the load, or use a dedicated buffer like the MAX44261.
Is MAX417CPA+ pin-compatible with other devices in the MAX406–MAX419 family?
Yes, all 8-pin variants in the MAX406–MAX419 family - including MAX406CPA, MAX407CPA, MAX409CPA, and MAX417CPA+ - share identical pinouts and electrical behavior across channels. The only differences are channel count (single/dual/quad) and internal configuration; MAX417CPA+ is the quad version, so pins 1–3, 5–7 correspond to four independent amplifiers.
What is the typical input offset voltage drift over temperature for MAX417CPA+?
The MAX417CPA+ exhibits a typical input offset voltage drift of 1.5µV/°C over the 0°C to +70°C operating range. This value is measured per device and specified in the Electrical Characteristics table of the MAX417 datasheet; it contributes <0.1mV total drift across the full temperature span, supporting stable DC-coupled gain without periodic auto-zeroing.
