The ADA4851 also has high output current making them ideal
in driving video signals. The AD4851-1 contains a disable
feature that will lower the power of the amplifier and put the
output in high impedance mode which makes it possible for
muxing applications.
PRODUCT OVERVIEW
The ADA4851-1 (Single), ADA4851-2 (Dual) and ADA4851-
4(Quad) are low cost, high speed, voltage feedback rail-to-rail
output op-amps. Despite the low cost, this family of amplifiers
has 175MHz Bandwidth, 250V/us slew rate, and can settle
within 25ns to 0.1% using only 3mA/amplifer of quiescent
current.
These amplifers are rated to work in the extended temprature
range (-40° to 125°C). The ADA4851-1 is available in SOT23-
6. The ADA4851-2 is available in µSOIC and the ADA4851-4
is available in TSSOP-14.
This family of amplifiers provides the user with true single
supply capability, allowing the signal levels on the input to
extend 200mV below negative rail and 1V within positive rail.
On the output the amplifier can swing within 50mV of the
either rail.
With 0.1dB flatness out to 15MHz and Differential gain and
phase of 0.05% and 0.05° this family of amplifiers is ideal for
video applications.
Combining its low cost with performance, these amplifiers are
ideal in consumer applications.
