Analog Devices Inc./Maxim Integrated MAX417ESA+T

Overview

MAX417ESA+T from Maxim Integrated is a dual, rail-to-rail input/output, micropower operational amplifier optimized for single-supply operation from +2.7V to +11V. It features 1.2µA max supply current per amplifier, 150kHz gain-bandwidth product, and ±1mV input offset voltage at +25°C. It is used in battery-powered sensor signal conditioning and low-power data acquisition systems.

For engineers reviewing the MAX417ESA+T datasheet, MAX417ESA+T pinout, MAX417ESA+T application, or MAX417ESA+T equivalent, key selection criteria include ultra-low quiescent current, rail-to-rail I/O swing, input offset voltage stability over temperature, and SO-8 package compatibility with space-constrained PCB layouts.

Technical Context

The MAX417ESA+T integrates two independent op-amps on a single die with matched internal transistor pairs enabling consistent DC performance across channels. Its input stage uses p-channel JFETs for femtoampere-level input bias current and rail-to-rail common-mode range down to V_EE and up to V_CC – 1.2V.

Output stage employs complementary bipolar transistors delivering rail-to-rail voltage swing within 15mV of each rail at 100kΩ load. The amplifier is internally compensated for unity-gain stability and operates without external components across its full specified temperature range (–40°C to +85°C).

FAQ

What is the maximum supply voltage rating for MAX417ESA+T?

The MAX417ESA+T is rated for operation from +2.7V to +11V DC. Exceeding +11V may cause permanent damage to the internal ESD protection structures. This upper limit is defined by oxide breakdown voltage and junction isolation margins in the proprietary BiCMOS process used for the MAX417ESA+T.

Does MAX417ESA+T support rail-to-rail input common-mode range?

Yes, the MAX417ESA+T supports rail-to-rail input common-mode range - from V_EE (GND) to V_CC – 1.2V. This is achieved using a p-channel JFET input stage, enabling accurate amplification of signals near ground in single-supply systems without level-shifting circuitry.

What is the typical input bias current of MAX417ESA+T at +25°C?

The typical input bias current of MAX417ESA+T is 100fA at +25°C, with a maximum of 1pA over the full –40°C to +85°C temperature range. This ultra-low value is critical for preserving signal integrity in high-impedance sensor interfaces such as pH probes and photodiode transimpedance stages.

Can MAX417ESA+T drive a 10kΩ load while maintaining rail-to-rail output swing?

Yes, the MAX417ESA+T maintains rail-to-rail output swing into loads ≥100kΩ. When driving a 10kΩ load, output swing degrades to within ~100mV of each rail due to output stage compliance limitations. For 10kΩ loads, consider adding an external follower or selecting a higher-output-current op amp.

Is MAX417ESA+T pin-compatible with other devices in the MAX406–MAX419 family?

Yes, MAX417ESA+T shares identical pinout and footprint with all 8-pin SO variants in the MAX406–MAX419 family (e.g., MAX407ESA, MAX409ESA). This allows drop-in substitution during design iteration or qualification, provided the selected variant meets the required gain-bandwidth, offset, and temperature specifications.
