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.
