The AMC8V108 and AMC8V208 (AMC8Vx08) are highly integrated current-output controllers optimized for optical networking applications.

The AMC8Vx08 include six dedicated 16-bit current-output digital-to-analog converters (IDACs), and two 16‑bit IDACs that can be configured to control high-output current generation circuits (IDAC+). The AMC8Vx08 also include a MUXOUT pin for monitoring the voltage and current on the current-output pins. An integrated high-precision internal reference eliminates the need for an external reference in most applications.

The IDAC outputs support full-scale output ranges of 250mA, 150mA, and 75mA, as well as an output range of –60mA (sink mode) supported on IDAC1 only. The IDAC+ outputs in internal current-output mode also support full-scale output ranges of 250mA, 150mA, and 75mA. Additionally, the IDAC+ outputs can be configured to operate with an external FET and sense resistor to simplify the design of very high-current outputs.

The IDAC and IDAC+ outputs operate from independent power supplies with a 275mV minimum headroom for power-dissipation optimization.
