3 Description

The OPA521 is a power line communications (PLC)

line driver that meets the conducted emissions

requirements in CENELEC bands A, B, C and D and

ARIB STD-T84 and FCC Part 15. This device is

designed for driving high-current, low-impedance

lines up to 1.9 A into reactive loads. With optimized

internal protection structures, the OPA521 requires

minimal external protection components that enable a

minimal system solution cost.

The OPA521 gives a closed-loop gain of 7 with a 3.8-

MHz bandwidth. The monolithic integrated circuit

gives high reliability in power line communication

applications.

The OPA521 transmit power amplifier operates from

a single supply from 7 V to 24 V. At a typical load

The

device

is

internally

protected

against

overtemperature and short-circuit conditions. Fault

detection flags indicate current and thermal limits. A

shutdown pin is available, and places the device into

a low-power state, consuming 40 µA (typical).

The OPA521 is available in a surface-mount, 5 mm ×

5 mm QFN, 20-pin package (RGW). Operation is

specified

over

the

extended

industrial

junction

temperature range of –40°C to +125°C.
