We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. The device by which variable gain can be obtained is known as programmable gain amplifier. By providing dual outputs, the MAX3522B eliminates the need for an external RF switch when selecting between two different upstream bandwidths. The LTC6912 is a family of dual channel, low noise, digitally programmable gain amplifiers (PGA) that are easy to use and occupy very little PC board space. Several popular VGA structures are discussed in detail in Chapter 3, and also the advantages and disadvantages are compared. This application note describes the Programmable Gain Amplifier (PGA) in the S12ZVLA128 microcontroller that is a member of the S12 MagniV 16-bit microcontroller devices. The LMH32401 device can be configured in a gain of 2 kΩ or 20 kΩ. The inverting amplifier circuit (a) and non-non inverting amplifier circuit (b) each have eight programmable gains, set by three logic-level inputs (D1, D2 and D3), that control the MOSFET switches. Abstract: Variable Gain Amplifier (VGA) is an integral part of Analog Systems, a special class of VGA called the Programmable Variable Gain Amplifier (PVGA) has revolutionized modern electronic systems. The AD8231 and LTC6915, which have zero-drift architectures, are useful for systems where precision performance is required over a wide range of temperatures. The single-supply circuit shown in the figure is an inverting peak detector with programmable gain. The MAX40204 is a high-precision, bidirectional, high-side current-sense amplifier (CSA) with a wide input common-mode range from -0.1V (ground sensing) to 36V.
