Precision and low-noise op amps are often used to condition the signal coming from a sensor (e.g., temperature, pressure, light) before it enters an analog-to-digital converter (ADC). In such a role, two particular op amp specifications are crucial for good system resolution: the input offset voltage and the input voltage noise. Maxim offers op amps with some of the best input offset voltage and input voltage noise specifications in the industry.

Select a precision/low noise op amp for your analog-to-digital application:
18 bits or more 
16 bits 
14 bits or less 

Autozero Technology

Maxim's autozero technology achieves high precision over time and temperature and eliminates low-frequency noise. The latest families of amplifiers that feature autozero technology work at much higher switching frequencies, making it easier to filter out noise while offering a wider, usable signal bandwidth.
