DESCRIPTION
The OPA2673 provides the high output current and
low distortion required in emerging Power Line
Modem driver applications. Operating on a single
+12V supply, the OPA2673 consumes a low 16mA/ch
quiescent current to deliver a very high 700mA output
current. This output current supports even the most
demanding Power Line Modem requirements with
greater than 460mA minimum output current (+25°C
minimum value) with low harmonic distortion.
Power control features are included to allow system
power consumption to be minimized. Two logic
control lines allow four quiescent power settings: full
power, 75% bias power in applications that are less
demanding, 50% bias power cutback for short loops,
and offline with active offline control to present a high
impedance even with large signals present at the
output pin.
Specified on ±6V supplies (to support +12V
operation), the OPA2673 also supports up to +13V
single or ±6.5V dual supplies. Video applications
benefit from a very high output current to drive up to
10 parallel video loads (15Ω) with < 0.1%/0.1° dG/dΦ
nonlinearity.
