| | Ultra-low distortion IF amplifier boasts 850 MHz bandwidth |
 | | However, when used in low power mode, power dissipation is reduced by enabling a single amplifier. |
 | | Besides combining advance bipolar process with proprietary linearization techniques to accomplish ultra-low distortion and high linearity over a wide bandwidth, the amplifier incorporates temperature compensation circuits to maintain high performance over a temperature range of -40°C to +85°C. For lowest noise and highest linearity, the LT5514 must be driven with a differential signal input. |
 | | In short, the PGA consists of an input variable attenuator “gain-control” block with 100 Ohm input impedance; two parallel, differential transconductance amplifiers — each with independent enable inputs; an internal bias block with internal voltage regulator; and a gain control logic block. |
