The AMC87208 is a highly integrated current-output controller optimized for optical networking applications.
The AMC87208 includes 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 AMC87208 also includes a 12‑bit, 1MSPS analog-to-digital converter (ADC). This ADC is used for internal and external signal monitoring, and as a temperature alarm monitor. 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.
