Texas Instruments  THS4271EVM

The THS4271EVM and THS4275EVM are designed to demonstrate the functionality and versatility of the device. There are three versions of the EVM: gains >+2/-1 with shutdown (THS4275EVM), gains >+2/-1 without shutdown (THS4271EVM), and noninverting unity gain configuration w/o shutdown (THS4271EVM-UG). The EVM is ready for power, input signal, and test instruments. Gain is adjustable by changing the feedback and gain resistors.
