Class-D amplifiers use switching technology to achieve high efficiency, often exceeding 90%, thereby requiring less power to operate, compared with that of other amplifier types. Because of the digital train used to drive the amplifier, many do not consider the Class-D amplifier a linear amplifier, yet many audio and radio manufacturers have ...
An ideal amplifier would be a totally linear device, but real amplifiers are only linear within limits. When the signal drive to the amplifier is increased, the output also increases until a point is reached where some part of the amplifier becomes saturated and cannot produce any more output; this is called clipping, and results in distortion.
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range.
Such amplifiers are referred to as linear amplifiers. 20 kW PEP linear amplifiers used by short wave radio station HCJB in both SSB and DRM broadcasts. It is also common to modify the gain of an amplifier operating class C so as to produce amplitude modulation. If done in a linear manner, this modulated amplifier is capable of low distortion.
Class-A amplifiers may be used in output stages of op-amps [11] (although the accuracy of the bias in low cost op-amps such as the "741" may result in class A or class AB or class B performance, varying from device to device or with temperature). They are sometimes used as medium-power, low-efficiency, and high-cost audio power amplifiers.
Many of PMI's converters, amplifiers, voltage references, and other linear ICs (including the REF0x and OP0x series) continue to be manufactured and marketed by Analog Devices, which currently maintain the largest share of the precision linear market (ADI sales = $2.5B, Maxim = $2.1B, Linear Technology = $1.1B).
A genuine Signetics NE5532N in PDIP package, made in 1990, on a modem board A Texas Instruments SA5532A in SOIC package on an audio distribution amplifier board . The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.
He is known for designing the Phase Linear 700, at 350 W per channel the most powerful consumer audio amplifier available in 1972. He went on to found the Carver Corporation in 1979, Sunfire in 1994, and the Bob Carver LLC in 2011 [ 2 ] which was sold to Jade Design in June, 2013. [ 3 ]
