TEXAS INSTRUMENTS THS4551DGKEVM 评估电路板, 差分放大器 新
The is an evaluation module for single THS4551 amplifier in DGK VSSOP-8 package. The THS4551 fully differential amplifier offers an easy interface from single ended sources to differential output required by high precision analogue to digital converters ADCs. This evaluation module is designed to quickly and easily demonstrate the functionality and versatility of amplifier. The EVM is ready to connect to power, signal source and test instruments through the use of onboard connectors. The amplifier is configured for single ended or differential input with gain of 1V/V to differential output at the device pins which is converted to single ended via a transformer to the output. It can be easily configured for other functions, gains and single or split supply operation. The THS4551DGKEVM has an onboard load for the amplifier of 1Kohm. The output transformer and resistor network converts this to a 50 ohm single ended output.
