Description |
Gains up to 1000 V/V and bandwidths to 4.5 GHz - get the right gain at the right time. |
Product Details
We offer a wide range of variable and programmable gain amplifiers capable of improving the dynamic range of a circuit with the ability to adjust the amplitude of the signal in real time. Our portfolio offers industry-leading zero drift, high-precision solutions with wide range of frequency from DC to 4.5 Ghz and wide-gain ranges up to 1000 V/V.).
Key Points Of SelectionÂ
Variable gain amplifiers (VGAs)
Wide bandwidth amplifiers with precision analog and digital gain control up to 4.5 GHz.
Programmable gain amplifiers (PGAs)
Digitally programmable precision amplifiers with binary and scope gain ranges up to 1,000 V/V.
Key Points Of Design
A major benefit of current mode topologies is the ground sensing capability. Rail to rail is also implemented by charge pumps at the expense of additional noise and an increase in die size.
PGAs differ from in amps in that they have a differential output. They don’t usually require an external gain setting resistor and in some cases they are used at gains lower than one. The attenuation feature is very useful in applications like structural testing a vibration control or universal IO modules for automation. These make great building blocks for integrated solution and they’re often part of high resolution analog to digital converter (ADC) as in the case of the ADS1220.
The latest PGA from the zero drift family is the PGA281. It has an input offset voltage of 5uV and a gain drift of 0.5ppm/ºC with EMI rejection of up to 120dB and a CMRR of 140dB! As for VGAs and DVGAs, they’re generally grouped into two types, constant output and constant input. In VGAs with constant output, the gain is adjusted to keep the output signal at a constant level while the input signal varies. In VGAs with constant input, the gain is adjusted to change the output signal while the input signal level is constant.
VGAs tend to be useful in applications requiring higher speed like sonar and photomultiplier control in industrial space, automatic gain control (AGC) in receivers for base stations, collision avoidance in automotive, video broadcasting and ultrasound. And just like in amps, there are several topologies that can be implemented depending on the target applications. The LMH6521 is just one of many DVGAs from TI that offer superior gain and phase matching.
