3 Description
The AMC60304 is a highly integrated, low-power
analog monitor and controller optimized for highcurrent
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 highprecision
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 lowlatency
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.
