Optical transceiver monitor and controller with 200-mA IDACs and multichannel ADC

The AMC60304 is a highly integrated, low-power analog monitor and controller optimized for high-current outputs. The device includes four 12-bit current output digital-to-analog converters (IDACs), a 12-bit, 1-MSPS analog-to-digital converter (ADC), supply and temperature alarm monitors, and a high-precision internal reference.

The AMC60304 IDACs support a full-scale output range of 200 mA with very-low power dissipation. These IDACs eliminate the need for external components to provide an accurate current bias.

The AMC60304 also includes four input pins that are multiplexed to the ADC and incorporate a low-latency window comparator. These features make this device an excellent choice for received signal strength indicator (RSSI) and loss-of-signal (LOS) detection. The ADC is also capable of measuring the voltage at the IDAC pins, thus enabling these outputs to be monitored.

The AMC60304 low power, high integration, very small size, and wide operating temperature range make this device an excellent choice as an all-in-one control circuit for optical modules.
