What is a Programmable Gain Amplifier?

A PGA, or programmable gain amplifier, is an electronic amplifier (often an op amp), of which the gain can be controlled by external analog or digital signals. These gains can be set from under 1V/V to over 100V/V. Examples for external digital signals can be SPI and I²C. The latest programmable gain amplifiers can also be programmed for offset voltage trimming and for use as active output filters.

Types of Programmable Gain Amplifiers

There are several different kinds of programmable gain amplifiers. At Future Electronics we stock many of the most common types categorized by maximum supply voltage, number of channels, nominal slew rate, maximum input offset voltage, gain, nominal gain bandwidth and packaging type. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for maximum supply voltage are 5.5 V and 36 V. Maximum input offset voltage can be up as high as 12 mV, with the most common size being 4.5 mV.

Applications for Programmable Gain Amplifiers:

Common applications for programmable gain amplifiers are motor control, signal and sensor conditioning, as well as in bar code readers and digital cameras. They can also be used for A/D converter driver applications, multiplexed analog applications, data acquisition, industrial instrumentation, test equipment and medical instrumentation.

Choosing the Right Programmable Gain Amplifier:

When you are looking for the right programmable gain amplifiers, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Nominal Slew Rate (0.0012 V/µs, 0.3 V/µs, 1.2 V/µs, 4.5 V/µs,…), Nominal Gain Bandwidth (80 kHz, 100 kHz, 900 kHz, 1 Mhz…) and number of channels (1, 2 or 4 channels) to name a few. You will be able to find the right programmable gain op amps to design a programmable gain instrumentation amplifier or for any circuit that may need a programmable gain op amp.

Programmable Gain Amplifiers in Production Ready Packaging or R&D Quantities

If the quantity of programmable gain amplifiers required is less than a full reel, we offer to customers many of our programmable gain amplifier products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times.
