Product details
Overview
MAX417CSA from Maxim Integrated is a single-channel, rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply operation. It features 1.2µA max supply current, 120kHz gain-bandwidth product, and operates from +1.8V to +5.5V. It is used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the MAX417CSA datasheet, MAX417CSA pinout, MAX417CSA application, or MAX417CSA equivalent, key selection criteria include quiescent current vs. bandwidth trade-off, rail-to-rail I/O performance at sub-2V supply, and SO-8 package thermal and layout compatibility in space-constrained designs.
Technical Context
The MAX417CSA belongs to the MAX406–MAX419 family of micropower op amps designed for low-voltage, single-supply systems. It uses a CMOS input stage enabling rail-to-rail input common-mode range and rail-to-rail output swing within 10mV of each rail at 100kΩ load.
It delivers 120kHz unity-gain bandwidth with 1.2µA supply current and supports operation down to +1.8V, making it suitable for direct interface with Li-ion battery discharge profiles and low-dropout regulator outputs without headroom loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Gain-Bandwidth Product | 120kHz - sufficient for DC–100Hz biomedical signal amplification (ECG, pulse oximetry) |
| Input Common-Mode Range | Rail-to-rail - allows full utilization of supply voltage for maximum dynamic range in single-supply configurations |
| Output Swing | Within 10mV of rails (100kΩ load) - preserves signal fidelity near supply limits in low-voltage ADC front-ends |
| Input Bias Current | 1pA max - minimizes offset error when driving high-impedance sources like pH electrodes or piezoresistive sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | 22µA supply current, 6.4MHz GBW, rail-to-rail output only (not input) | Higher speed and power; unsuitable for multi-year coin-cell operation but better for faster sensor sampling | Select when bandwidth >100kHz is required and supply current <2µA is not critical |
| LPV811DBVR | 320nA supply current, 10kHz GBW, rail-to-rail I/O, lower VOS (150µV) | Lower power and offset, but insufficient bandwidth for ECG or pulse oximetry AC coupling | Select for ultra-low-power DC-coupled applications (e.g., pH meter front-end) where bandwidth <20kHz suffices |
Compared with TLV2461CDR and LPV811DBVR, the MAX417CSA uniquely balances 120kHz bandwidth, rail-to-rail I/O, and 1.2µA supply current-making it optimal for battery-powered biomedical signal chains requiring both precision and responsiveness.

FAQ
What is the operating temperature range specified for the MAX417CSA?
The MAX417CSA is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated for use in consumer electronics, portable test equipment, and indoor industrial sensor nodes where ambient conditions remain within this envelope. The 'C' suffix in MAX417CSA explicitly denotes this temperature grade, distinct from 'E' (–40°C to +85°C) or 'M' (–55°C to +125°C) variants.
Does the MAX417CSA support rail-to-rail input and output operation?
Yes, the MAX417CSA supports true rail-to-rail input common-mode range and rail-to-rail output swing. Its CMOS input stage allows input voltages from VSS to VCC, and its output can swing within 10mV of either rail under 100kΩ load. This capability is fully characterized in the MAX417CSA datasheet across its entire supply range (+1.8V to +5.5V) and temperature range (0°C to +70°C).
What package type is used for the MAX417CSA and what are its key mechanical dimensions?
The MAX417CSA is supplied in an 8-pin SO (Small Outline) package, designated S8-2 per Maxim's package documentation. Its body measures 4.9mm × 3.9mm, thickness is 1.75mm, and lead pitch is 1.27mm. The gull-wing leads are compatible with standard reflow soldering profiles and IPC-7351B land patterns for SOIC-8.
Can the MAX417CSA be used with a single 1.8V supply?
Yes, the MAX417CSA is fully specified to operate from +1.8V to +5.5V. At 1.8V, it maintains rail-to-rail input and output functionality, 120kHz gain-bandwidth product, and 1.2µA max supply current. This makes the MAX417CSA suitable for direct integration with energy-harvesting systems and ultra-low-voltage microcontrollers that regulate below 2.0V.
Are there any unused pins on the MAX417CSA, and how should they be handled?
Yes, pins 5, 6, and 8 of the MAX417CSA are marked NC (No Connection) in the official datasheet and must remain unconnected. These pins have no internal bond wire or circuit connection. Leaving them floating is acceptable; however, grounding them is not recommended as it may introduce parasitic capacitance or leakage paths that affect noise performance or stability in high-impedance configurations.
