Description
The ZL40120 is a low power, quad, current feedback
operational amplifier offering high performance at a low
cost. The device provides a very high output current
drive capability of 65mA while requiring only 3.3mA of
static supply current per channel. This feature makes
the ZL40120 the ideal choice where a high density of
high speed devices is required.

Ordering Information
ZL40120/DCA (tubes) 14 lead SOIC
ZL40120/DCB (tape and reel) 14 lead SOIC
-40°C to +85°C
The 280MHz Av=+1V/V small signal bandwidth and
1100V/µs slew rate make the device an excellent
solution for component video applications such as
driving RGB signals down significant cable lengths.
Other applications which may take advantage of the
ZL40120 dynamic performance features and matched
amplifiers include low cost high order active filters and
twisted pair driver/receivers.
