Product details
Overview
MAX9614AXT+T from Maxim Integrated is a low-power, single-channel, rail-to-rail input/output precision operational amplifier with MOS inputs, 2.8MHz gain-bandwidth, 100µV max input offset voltage, and active-low shutdown pin - designed for photodiode transimpedance amplification, sensor signal conditioning, and anti-aliasing filtering in automotive-grade industrial systems operating from 2.5V to 5.5V.
For engineers reviewing the MAX9614AXT+T datasheet, MAX9614AXT+T pinout, MAX9614AXT+T application, or MAX9614AXT+T equivalent, this page delivers verified electrical parameters, SC70-6 package layout, shutdown timing behavior, RF immunity performance, and real-world use cases in medical sensors and portable instrumentation where ultra-low quiescent current (175µA operating / 1µA shutdown) and sub-100µV VOS autotrim are critical.
Technical Context
The MAX9614AXT+T implements a BiCMOS process-based precision op amp architecture with integrated power-up autotrim that reduces input offset voltage to ≤100µV across -40°C to +125°C via internal calibration triggered by POR. Its CMOS input stage delivers pA-level input bias current (1.55pA typ at +25°C), enabling high-impedance sensor interfacing without significant error.
It features robust on-chip EMI filtering for RF immunity, rail-to-rail output swing (VOL = 11mV @ 10kΩ, VOH = VCC–2mV), and stable operation into 200pF capacitive loads - supporting direct ADC driving and active filter implementation without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports single-supply operation in battery-powered and automotive systems. |
| Input Offset Voltage (max) | 100µV - guaranteed after power-up autotrim, enabling high-accuracy DC-coupled signal chains. |
| Quiescent Current | 175µA (operating), 1µA (shutdown) - extends battery life in portable medical and sensor nodes. |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters up to ~1.3kHz and fast-sampling ADC front-ends. |
| Slew Rate | 1.3V/µs - ensures faithful reproduction of medium-frequency analog signals without distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ICT | Lower GBW (8MHz), higher ICC (250µA), no shutdown, wider VOS range (1.5mV max). | Lacks automotive temp range and autotrim; suited for cost-sensitive consumer apps, not medical/industrial. | Choose only if shutdown and <100µV VOS are noncritical and higher speed is needed. |
| MCP6001T-E/OT | Higher VOS (1.5mV max), no autotrim, lower RF immunity, same SC70-6 package. | Not qualified for automotive temp range; lacks EMI filtering - unsuitable for noisy environments. | Select only for non-automotive, non-medical designs where ultra-low offset is unnecessary. |
Compared with TSV911ICT and MCP6001T-E/OT, MAX9614AXT+T uniquely combines automotive-grade temperature operation, power-up autotrim, 1µA shutdown, and integrated RF immunity - making it the only option among the three for precision, low-power, noise-resilient sensor interfaces in harsh environments.

FAQ
What is the maximum input offset voltage specification for MAX9614AXT+T over temperature?
The MAX9614AXT+T guarantees a maximum input offset voltage of 100µV after its internal power-up autotrim sequence completes. Over the full –40°C to +125°C operating range, the datasheet specifies 750µV max before autotrim and 165µV max after autotrim - with typical post-trim values near 17µV at +25°C. This autotrim function is intrinsic to MAX9614AXT+T and occurs automatically each time VCC rises above the POR threshold.
Does MAX9614AXT+T require external components for stable operation with capacitive loads?
No, MAX9614AXT+T is characterized to remain stable with up to 200pF capacitive load without external isolation resistors or compensation networks. The device's internal compensation and robust phase margin allow direct driving of ADC input capacitance and long PCB traces - a key design advantage confirmed in the Typical Operating Characteristics section of the MAX9614AXT+T datasheet.
How does the shutdown feature of MAX9614AXT+T behave during power cycling?
The MAX9614AXT+T shutdown pin is active-low and places both inputs and output into high-impedance states, reducing supply current to ≤1µA. Exiting shutdown does not trigger autotrim - the device retains its last calibrated offset value. Power cycling (full VCC ramp) reinitiates the 10ms autotrim sequence. This behavior ensures predictable startup timing and consistent DC accuracy across sleep/wake cycles in MAX9614AXT+T-based systems.
What is the minimum supply voltage required for full rail-to-rail output swing in MAX9614AXT+T?
MAX9614AXT+T achieves rail-to-rail output swing down to 11mV above GND and within 2mV of VCC across its entire specified supply range of 2.5V to 5.5V. At the minimum 2.5V supply, the output still delivers VOH ≥ 2.498V and VOL ≤ 0.011V into a 10kΩ load - enabling full dynamic range utilization in low-voltage battery-powered applications using MAX9614AXT+T.
Is MAX9614AXT+T qualified for automotive applications?
Yes, MAX9614AXT+T is explicitly rated for the automotive temperature range of –40°C to +125°C and is manufactured in an AEC-Q100–compatible process. Its specifications - including input offset voltage, CMRR, PSRR, and supply current - are fully guaranteed across this range, and its RF immunity features address common EMI challenges in automotive cabins. This qualification is documented in the Ordering Information and Absolute Maximum Ratings sections of the MAX9614AXT+T datasheet.
