The AFE032 transmit power amplifier operates from a

single supply in the range of 7 V to 24 V. At typical

load current (I_OUT= 1.5 A_PEAK), a wide output swing

provides a 12-V_PPcapability with a nominal 15-V

supply.

Standards:

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.
