Products/Services for high input impedance amplifier
Instrumentation amplifiers are differential amplifiers that have been optimized for use with DC signals. They are characterized by high gain, high common mode rejection ratio (CMRR), and high input impedance. Search by Specification | Learn More about Instrumentation Amplifiers
Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network). The purpose of matching these two impedances is to minimize wave reflection and/or to maximize the transfer of power between the system and the load. Search by Specification | Learn More about Impedance Matching Networks
Instrumentation amplifier chips are precision amplifier circuits with both high-impedance differential inputs and high common-mode rejection. Search by Specification | Learn More about Instrumentation Amplifier Chips
Amplifier and comparator chips are board-level components for amplifying voltage, current, or power. Search by Specification | Learn More about Amplifier and Comparator Chips
Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements. Search by Specification | Learn More about Signal Amplifiers
Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage. Search by Specification | Learn More about Data Acquisition Input Modules
RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude. Search by Specification | Learn More about RF Amplifiers
Sample-and-hold amplifiers freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period. Search by Specification | Learn More about Sample-and-Hold Amplifiers
Power operational amplifiers (POA) are used to increase the power of low-level signals in applications that drive low impedances or reactive loads. They dissipate excess energy as heat, deliver extensive current, and can sustain relatively high supply voltages. Search by Specification | Learn More about Power Operational Amplifiers
Piezoelectric drivers and piezoelectric amplifiers are power sources that provide the high voltage levels needed to drive other piezoelectric devices such as actuators, motors, transducers, and sensors. Search by Specification | Learn More about Piezoelectric Drivers and Piezoelectric Amplifiers
Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers. Learn More about Operational Transconductance Amplifiers (OTA)
Power MOSFETs are majority carrier devices which have high input impedance and do not exhibit minority carrier storage effects, thermal runaway, or secondary breakdown. Power MOSFETs have higher breakdown voltages than bipolar junction transistors (BJTs) and can be used in higher frequency applications where switching power losses are important. Search by Specification | Learn More about Power MOSFET
Buffer amplifiers have unity gain. They are used to match impedances between two devices, or as isolators. Search by Specification | Learn More about Buffer Amplifiers
Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive. Search by Specification | Learn More about PWM Amplifier Chips
Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions. Search by Specification | Learn More about Operational Amplifiers
