SGM8435-2
SGM8435-2 is Wide-Band Differential PLC Driver manufactured by SG Micro.
DESCRIPTION
The SGM8435-2 is a current feedback, differential wide-band PLC driver, which consists of dual, high voltage, low noise and high slew rate amplifiers. The high crest factor signals can be driven by the device with very low distortion levels in the power meter. These features make SGM8435-2 very suitable for power meter wide-band PLC applications. In order to avoid line surges caused by lightning, very reliable protection measures are taken at the output pins of the driver.
The SGM8435-2 can operate from 5V to 26V single supply. And it maintains wide bandwidth and high linearity over the whole full-scale range of power supply.
A disable control (DIS) pin is used to control the operation modes of the device. When DIS pin is high or floating, SGM8435-2 is in power-down mode. When DIS pin is low, SGM8435-2 is in full-power working mode.
The SGM8435-2 is available in a Green TQFN-4×4-24L package. It operates over an ambient temperature range of -40℃ to +85℃.
