What are the key features of MAX40078AUD+T?
- 120 dB typical common-mode rejection ratio (CMRR) with 90 dB minimum, enabling precision differential signal amplification in noisy industrial environments
- Ultra-low input bias current of 0.026 µA maximum at 25°C, minimizing DC offset errors in high-impedance sensor interfaces
- Voltage-feedback architecture with internal frequency compensation for stable closed-loop operation across a wide range of gain configurations
- Quad op-amp in a compact 14-pin TSSOP (4.4 x 4.4 mm) package, reducing board area in multi-channel signal conditioning designs
What is MAX40078AUD+T used for?
MAX40078AUD+T is well-suited for precision sensor signal conditioning in medical instrumentation, industrial data acquisition systems, and weigh-scale electronics where 120 dB CMRR and sub-100 nA bias current are critical. Its quad configuration in a single 14-pin TSSOP package makes it an efficient choice for multi-channel transducer amplifiers, bridge amplifiers, and active filter designs. The device also serves in audio signal processing, precision voltage references, and test-and-measurement front ends that demand high-accuracy, low-drift amplification.

Frequently Asked Questions
What is the CMRR specification of MAX40078AUD+T and why does it matter for differential signal applications?
MAX40078AUD+T achieves a typical CMRR of 120 dB with a guaranteed minimum of 90 dB, meaning common-mode noise such as 50 Hz or 60 Hz power-line interference is attenuated by a factor of at least 31,623:1, ensuring accurate differential measurements in industrial sensors, bridge amplifiers, and medical instrumentation front ends.
How low is the input bias current of MAX40078AUD+T and what sensor types benefit from this specification?
The MAX40078AUD+T has a maximum input bias current (IIB) of 0.026 µA (26 nA) at 25°C and an average of 0.00026 µA (260 pA), making it ideal for high-impedance sensors such as piezoelectric transducers, pH electrodes, photodiodes, and capacitive humidity sensors where even small bias currents would produce significant voltage errors.
How many amplifier channels does MAX40078AUD+T provide and what package does it come in?
MAX40078AUD+T integrates 4 independent operational amplifier channels in a single 14-pin TSSOP package measuring approximately 4.4 x 4.4 mm, allowing designers to replace four discrete single op-amps with one quad device, cutting board space by up to 75% in multi-channel analog front-end designs.
When would a designer choose MAX40078AUD+T over a standard general-purpose op-amp for a precision ADC front end?
A designer selects MAX40078AUD+T over general-purpose op-amps when the ADC front-end must achieve better than 16-bit accuracy, since the 120 dB CMRR and 26 nA maximum bias current prevent the offset and noise errors that would degrade a 16-bit or 18-bit ADC's dynamic range in high-resolution data acquisition systems.
