Amplifiers

We offer a wide selection of amplifiers and comparators for signal conditioning, monitoring, and control applications.

You can use Maxim’s op amps to make amplifiers, comparators, log amplifiers, filters, oscillators, data converters, level translators, references, and more. You can also use them to accomplish mathematical functions like addition, subtraction, multiplication, and integration.

A comparator is analogous to a 1-bit ADC. A simple comparator can be implemented using an op amp without negative feedback. Its high voltage gain allows it to resolve very small differences in input voltage. However, op amps lack special features which comparators typically include, such as hysteresis and internal references and they are usually much slower than our dedicated comparator IC’s.

Current-sense amplifiers (CSAs) monitor current flow through a shunt (sense) resistor and provide closed-loop feedback of system loads. Our current-sense amps are optimized for a wide range of applications, including overcurrent protection and optimization of power monitoring systems. We offer a wide range of current-sense amplifiers for both high-side sensing and low-side sensing, as well as unidirectional or bidirectional current flow through the sense resistor

Our specialized amplifiers have multiple features suited for a wide range of applications. This range includes differential, instrumentation/difference, logarithmic, programmable gain, integrated comparator and reference and programmable voltage/current drivers.
