3 Description

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.
