AD8336-EVALZ

ANALOG DEVICES  AD8336-EVALZ.  评估板, 可变增益放大器

The is an evaluation board for AD8336 device. The AD8336 is a low noise, single ended, linear in dB, general purpose variable gain amplifier, usable over a large range of supply voltages. It features an uncommitted preamplifier with a usable gain range of 6dB to 26dB established by external resistors in the classical manner. The VGA gain range is 0dB to 60dB and its absolute gain limits are -26dB to +34dB. When the preamplifier gain is adjusted for 12dB, the combined 3dB bandwidth of the preamp and VGA is 100MHz, and the amplifier is fully usable to 80MHz. With ±5V supplies, the maximum output swing is 7Vpp. To change the value of the gain of the preamp or to change the gain polarity to inverting, alter the component values or install components in the alternate locations provided. All components are standard 0603 size.
