The AMC8V108
and AMC8V208 (AMC8Vx08) are
highly integrated current-output controllers optimized for optical networking
applications.
The AMC8Vx08 include 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 AMC8Vx08 also include a MUXOUT pin for monitoring the voltage and current
on the current-output pins. 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.
