Product details
Overview
MAX9616AXA+T from Maxim Integrated is a dual, rail-to-rail input/output, low-power precision operational amplifier with MOS inputs, 2.8MHz gain-bandwidth, 175µA quiescent current per amplifier, and 100µV max input offset voltage over -40°C to +125°C - designed for high-impedance sensor signal conditioning in automotive and industrial ADC front-ends.
For engineers reviewing the MAX9616AXA+T datasheet, MAX9616AXA+T pinout, MAX9616AXA+T application, or MAX9616AXA+T equivalent, this page delivers verified electrical parameters, SC70-8 pin mapping, real-world use cases in photodiode transimpedance and anti-aliasing filter design, and two validated alternative op amps with documented functional and packaging differences.
Technical Context
The MAX9616AXA+T implements a BiCMOS process-based dual op amp architecture with auto-calibrating input offset voltage (VOS < 100µV after power-up autotrim), enabling stable DC performance across temperature and supply variation. Its CMOS input stage delivers sub-picoampere bias current at low common-mode voltages, critical for high-Z sensor interfaces.
It features rail-to-rail output swing with 11mV VOL (at 10kΩ) and VCC–2mV VOH, supporting single-supply operation down to 2.5V. RF immunity is enhanced via internal EMI filtering, making it suitable for portable and noisy industrial environments without external shielding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports direct interface with 3.3V and 5V microcontrollers and ADCs without level-shifting. |
| Input Offset Voltage (max) | 100µV at +25°C; 750µV over –40°C to +125°C - enables accurate DC-coupled amplification of µV-level sensor signals. |
| Quiescent Current (per amp) | 170–350µA - allows battery-powered multi-channel sensing systems to operate >1 year on coin cells. |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters up to ~1.3kHz corner frequency and fast settling in ADC driver applications. |
| Input Bias Current (max) | 1.55nA at +125°C - preserves signal integrity when driving high-impedance sources like photodiodes or pH electrodes. |
| Common-Mode Rejection Ratio | 78dB min over full temp range - rejects noise from shared ground paths in mixed-signal PCB layouts. |
| Output Voltage Swing | Rail-to-rail: VOL = 11mV, VOH = VCC–2mV at 10kΩ - maximizes dynamic range in single-supply 3.3V systems. |
Pinout & Package
MAX9616AXA+T is housed in an 8-pin SC70 package (X8SN-1 outline), measuring 2.0mm × 2.1mm × 0.95mm, with RoHS-compliant lead-free finish indicated by the "+" suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA+ | Noninverting input of amplifier A - high-impedance CMOS node for precision sensor signal routing. |
| 2 | INA− | Inverting input of amplifier A - matched to INA+ for optimal common-mode rejection in differential configurations. |
| 3 | OUTA | Amplifier A output - rail-to-rail capable, drives ADC inputs or active filters directly. |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to maintain PSRR/CMRR. |
| 5 | INB− | Inverting input of amplifier B - electrically isolated from amplifier A for independent channel operation. |
| 6 | INB+ | Noninverting input of amplifier B - identical input structure to INA+, enabling matched dual-channel designs. |
| 7 | OUTB | Amplifier B output - fully independent output stage; no crosstalk with OUTA at frequencies ≤1MHz. |
| 8 | VCC | Positive supply - requires local 0.1µF ceramic bypass capacitor to GND for stability and noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Power-Up Autotrim | Self-calibrates input offset to <100µV in 10ms; eliminates manual trimming and drift compensation circuitry. |
| RF Immunity | Integrated EMI filters suppress interference from GSM, Bluetooth, and Wi-Fi bands - no external ferrite beads required. |
| Rail-to-Rail I/O | Full-swing input range (–0.1V to VCC–1.4V) and output swing (to within 2mV of rails) maximize usable signal headroom. |
| Low Input Bias Current | 1.55pA typical at +25°C, <1.55nA at +125°C - enables stable operation with >100MΩ source impedances. |
| Capacitive Load Drive | Stable with up to 200pF load - supports direct connection to ADC input capacitors without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2782IDR | 2.5V–5.5V supply, 1.8MHz GBW, 125µA IQ, 1.5mV VOS max - lower bandwidth and higher offset than MAX9616AXA+T. | Not qualified for automotive AEC-Q100; lacks autotrim and RF immunity features. | Choose for cost-sensitive consumer applications where 1.8MHz bandwidth suffices and extended temperature range is not required. |
| OPA2333AIDR | 1.8V–5.5V supply, 350kHz GBW, 17µA IQ, 12µV VOS max - ultra-low power but significantly lower bandwidth. | Zero-drift architecture enables near-zero drift, but slower response limits use in anti-aliasing filters above 100Hz. | Prefer for ultra-low-power, high-precision DC measurement only; avoid where >1kHz signal bandwidth is needed. |
Compared with TLV2782IDR and OPA2333AIDR, MAX9616AXA+T uniquely balances 2.8MHz bandwidth, 100µV VOS max, automotive temperature rating, and integrated autotrim - making it the only option among the three qualified for high-speed, high-accuracy sensor front-ends in harsh environments.

FAQ
What is the operating temperature range of the MAX9616AXA+T?
The MAX9616AXA+T is specified for continuous operation from –40°C to +125°C, meeting automotive AEC-Q100 Grade 0 requirements. This range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliability in under-hood and industrial control environments where thermal cycling is severe.
Does the MAX9616AXA+T include shutdown functionality like the MAX9614?
No, the MAX9616AXA+T does not include a shutdown pin. Unlike the MAX9614AXT+T (which has an active-low SHDN pin), the MAX9616AXA+T is a dual op amp without power-management control. Shutdown capability is exclusive to the single-channel MAX9614 variant, as confirmed in the Pin Description and Ordering Information tables.
What is the purpose of the power-up autotrim feature in the MAX9616AXA+T?
MAX9616AXA+T performs an automatic 10ms power-up autotrim that reduces input offset voltage to <100µV by compensating for process, temperature, and supply variations. This eliminates the need for external trimming components or software calibration routines - critical for maintaining accuracy in unattended industrial sensors and automotive subsystems.
Can the MAX9616AXA+T drive a 200pF capacitive load without oscillation?
Yes, the MAX9616AXA+T is characterized to remain stable with up to 200pF capacitive load, as stated in the Electrical Characteristics table under "Capacitive Loading". This makes it suitable for direct connection to ADC input capacitors and long PCB traces without requiring series isolation resistors or external compensation networks.
Is the MAX9616AXA+T pin-compatible with other dual op amps in SC70-8 packages?
No, the MAX9616AXA+T uses a proprietary 8-pin SC70 pinout (INA+, INA−, OUTA, GND, INB−, INB+, OUTB, VCC) that differs from industry-standard dual op amp layouts such as SOIC-8 or MSOP-8. It is not pin-compatible with generic dual op amps - PCB layout must follow the exact pin mapping shown in the datasheet's Pin Configuration diagram.
