The AFE032 transmit power amplifier operates from a
single supply in the range of 7 V to 24 V. At typical
load current (IOUT = 1.5 APEAK), a wide output swing
provides a 12-VPP capability with a nominal 15-V
supply.

The device is internally protected against
overtemperature and short-circuit conditions. The
device also provides a selectable current limit. An
interrupt output is provided, indicating current limit,
thermal limit, and undervoltage. A shutdown pin is
also available, and can be used to quickly place the
device into the lowest-power state. Each functional
block can be enabled or disabled to optimize power
dissipation through the serial peripheral interface

The AFE032 is a low-cost, integrated, power-line
communications (PLC), analog front-end (AFE)
device capable of transformer-coupled connections to
the power-line while under the control of a digital
signal processor (DSP) or microcontroller. This
device is ideal for driving high-current, low-impedance
lines up to 1.9 A into reactive loads.
