Further your technical expertise with online and in-person instruction. The AD8369 is a high performance digitally controlled variable gain amplifier (VGA) for use from low frequencies to a –3 dB frequency of 600 MHz at all gain codes. Low noise, low distortion, with good signal transmission capability. The AD8331ARQZ is an Ultralow Noise Variable Gain Amplifier with Preamplifier and Programmable RIN optimized for ultrasound systems. If you are not experienced with the distribution of a TV signal you should not purchase this item. Such a device has a gain that is controlled by a dc voltage or, more commonly, a digital input. You won’t have to choose your products at random anymore. This device is known as a variable gain amplifier (VGA), or programmable gain amplifier (PGA). Every 6dB of gain equates to a doubling of voltage; as such, a hypothetical amplifier with a voltage gain of 30dB will increase voltage by 2^5, or by a factor of 32. About Variable Gain Amplifiers (RF VGA or DVGA) You can think of a variable gain amplifier for RF systems (RF VGA) as simply combining an amplifier (gain device) and an attenuator in the same package. Our portfolio of digital VGAs includes solutions with high linearity and high output power across a large bandwidth without external matching. Functional Safety and Automotive Security, Commercial Support and Engineering Services, Slavery The AD603 is a low noise, voltage controlled amplifier for radio frequency (RF) and intermediate frequency (IF) automatic gain control (AGC) systems. The gain range is 1 to 10,000. 1, easy to use 2, with a higher performance of the score vertical design 3, single power and dual power supply Rail-to-rail output swing, 5, input voltage range below ground voltage 150mV (single power supply) 6, 1 low power consumption, maximum supply current of 550 HA 7, set the gain through an external resistor, 8, high-precision DC performance Gain accuracy: 0.10% (G=1) Gain accuracy: 0.35% (G >1) Gain draft: 10 ppm (G= 1) Input bias current: 25 nA (max), application Electronic scale ECG and medical instruments Sensor interface data collection system Industrial process control Battery-powered portable devices, A wideband (30MHz-4000MHz), high-performance, general purpose LNA module with a built-in variable attenuator to maximize usability and portability, The attenuation can be controlled either with the on-board potentiometer (analog control) or push button array (digital control), Dual amplifier design with adjustable gain (20dB-50dB at 100MHz), low noise figure and low power consumption. gain, bandwidth and noise of the VGA from the overall receiver requirements. The amplifier circuits are normally designed for a fixed amount of gain.
