THS3215 - Texas Instruments

THS3215 Differential to Single-Ended DAC Output Amplifier

The THS3215 combines the key signal-chain components required to interface with a complementary-current output, digital-to-analog converter (DAC). VREF The flexibility provided by this two-stage amplifier system delivers the low distortion, dc-coupled, differential to single-ended signal processing required by a wide range of systems.The input stage buffers.
