The AMC60804T is a highly integrated, low-power analog monitor and controller for optical transceiver applications.

The AMC60804T includes four 12-bit current output digital-to-analog converters (IDACs) and four 12-bit voltage output DACs (VDACs) with programmable output ranges. The device also includes a 12-bit, 1-MSPS analog-to-digital converter (ADC) used for external and internal signal monitoring, supply and temperature alarm monitors, and a high-precision internal reference.

The AMC60804T VDACs support both positive and negative output-range operation and are capable or sourcing and sinking up to 50 mA, making them an excellent choice for biasing optical modulators. Additionally, the AMC60804T IDACs support a full-scale output range of 200 mA with very-low power dissipation. The IDACs eliminate the need for external components to bias laser diodes. In combination, the AMC60804T four VDACs and four IDACs enable accurate biasing of electro-absorption modulated lasers.

The AMC60804T 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, as well as the current being sourced or sinked by the VDACs, thus enabling these outputs to be monitored.

The AMC60804T 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.
