THS3217 - Texas Instruments

THS3217 DAC-Output Amplifier

The THS3217 combines the key signal-chain components required to interface with a complementary-current output, digital-to-analog converter (DAC). The flexibility provided by this twostage amplifier system delivers the low distortion, dccoupled, differential to single-ended signal processing required by a wide range of systems. The input stage buffers the DA.
