Product details
Overview
MAX9617AXT+T from Maxim Integrated is a single-channel, zero-drift, rail-to-rail input/output operational amplifier in a 6-pin SC70 package. It delivers 1.5MHz gain-bandwidth, 59µA quiescent current, and ≤10µV max input offset voltage over –40°C to +125°C, enabling precision signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the MAX9617AXT+T datasheet, MAX9617AXT+T pinout, MAX9617AXT+T application, or MAX9617AXT+T equivalent, this page provides verified electrical specs, validated SC70 pin mapping, real-world use cases in ECG front-ends and loop-powered transmitters, and two confirmed alternative op amps with documented functional trade-offs.
Technical Context
The MAX9617AXT+T employs an autozero architecture to eliminate 1/f noise and maintain <10µV input offset drift across temperature, making it suitable for DC-coupled, low-frequency measurement paths. Its internal charge pump enables true rail-to-rail input operation without crossover distortion, supporting common-mode voltages from GND to VDD.
It operates from a single 1.8V–5.5V supply, achieves unity-gain stability, and drives capacitive loads up to 400pF without external compensation. The device is not shutdown-capable-unlike the MAX9619AXT+T-and is specified only as a single-channel amplifier with no dual-channel or enable logic functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.5MHz - supports stable amplification of signals up to ~150kHz at gain = 10 |
| Quiescent Current | 59µA - extends battery life in portable devices operating >1000 hours on coin-cell power |

Pinout & Package
MAX9617AXT+T is housed in a 2mm × 2mm, 6-pin SC70 package (package code X6SN+1, outline 21-0077), RoHS-compliant and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN− | Inverting input - accepts differential or single-ended feedback networks; referenced to GND |
| 2 | GND | Analog ground - must be connected to low-impedance system ground plane to minimize PSRR degradation |
| 3 | IN+ | Noninverting input - high-impedance CMOS node; sensitive to layout-induced leakage currents |
| 4 | VDD | Positive supply - requires local 0.1µF ceramic bypass capacitor to GND for high-frequency PSRR |
| 5 | OUT | Amplifier output - capable of driving 100kΩ loads to within 12mV of rails; stable with ≤400pF capacitance |
| 6 | VDD | Positive supply - second VDD pin for improved thermal and current distribution; tied internally to Pin 4 |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6V81-E/OT | Single 5-pin SOT-23; 1.8V–5.5V; 600nA max IB; 1.8MHz GBW; 25µV max VOS | Higher input bias current limits use with >1MΩ sensor sources; wider offset spec reduces DC accuracy | Select when higher bandwidth is prioritized over ultra-low drift and noise. |
| LTC2050CS5#TRMPBF | Single 5-pin TSOT-23; 2.7V–6V; 125pA max IB; 3MHz GBW; 10µV max VOS; 0.25µVP-P 0.1–10Hz noise | Requires ≥2.7V supply; higher quiescent current (125µA) reduces battery life vs. MAX9617AXT+T | Select when lower noise floor is critical and system supply allows ≥2.7V operation. |
Compared with MAX9617AXT+T, the MCP6V81 offers higher bandwidth but trades off input bias current and offset voltage; the LTC2050 delivers lower noise and matching offset but consumes >2× the supply current and lacks 1.8V operation capability.

FAQ
What is the maximum operating temperature range for the MAX9617AXT+T?
The MAX9617AXT+T is fully specified from –40°C to +125°C, with all key parameters-including input offset voltage, supply current, and gain-bandwidth-guaranteed across this automotive-grade temperature range. Junction temperature is limited to +150°C, and the device remains functional beyond +125°C with appropriate thermal derating per its 245.4mW power dissipation rating at +70°C ambient.
Does the MAX9617AXT+T support shutdown mode?
No, the MAX9617AXT+T does not include a shutdown function. Shutdown capability is exclusive to the MAX9619AXT+T variant, which adds a dedicated SHDN pin. The MAX9617AXT+T has no enable/disable control; it operates continuously when powered, drawing 59µA typical quiescent current at +25°C and up to 111µA across the full –40°C to +125°C range.
What is the input common-mode voltage range of the MAX9617AXT+T?
The MAX9617AXT+T supports a rail-to-rail input common-mode range from –0.1V to VDD + 0.05V over –40°C to +125°C. This is enabled by an internal charge pump that generates a boosted internal supply, allowing true CMOS input stages to operate without crossover distortion-even at the negative rail-critical for single-supply sensor interfaces where signals swing near ground.
Can the MAX9617AXT+T drive capacitive loads without oscillation?
Yes, the MAX9617AXT+T is stable driving capacitive loads up to 400pF with unity-gain configuration. For loads exceeding 400pF, stability can be restored by adding a series isolation resistor (e.g., 10Ω–100Ω) between the output and the capacitive load, as validated in Maxim's typical operating characteristics graphs. No external compensation capacitors are required for standard applications.
What package type and footprint does the MAX9617AXT+T use?
The MAX9617AXT+T uses a 6-pin SC70 package (outline 21-0077, land pattern 90-0189), measuring 2.0mm × 2.0mm × 0.95mm. It features two VDD pins (Pins 4 and 6), IN+ (Pin 3), IN− (Pin 1), OUT (Pin 5), and GND (Pin 2). The top mark is "ADS", and the package is RoHS-compliant (indicated by the "+" suffix).
