LMH6521SQE

Программируемый/переменный усилитель, 2 канал(-ов), 1 Усилитель, 1.2 ГГц, -40 °C, 85 °C.

The LMH6521SQE is a two high performance digitally controlled Variable Gain Amplifier for use with wideband direct conversion. Both channels of the LMH6521 has an independent, digitally controlled attenuator followed by a high linearity, differential output amplifier. Each block has been optimized for low distortion and maximum system design flexibility. Each channel has a high speed power down mode. The internal digitally controlled attenuator provides precise 0.5dB gain steps over a 31.5dB range. Serial mode programming utilizes the SPI interface. A pulse mode is also offered where simple up or down commands can change the gain one step at a time. The output amplifier has a differential output allowing 10VPPD signal swings on a single 5V supply. The low impedance output provides maximum flexibility when driving filters or analog to digital converters.
