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.

stresses that the package exerts on the die, permanently shifting
the parametric performance of the ADA4851. Exceeding a
junction temperature of 175°C for an extended period of time
can result in changes in the silicon devices potentially causing
failure.

Operating Temperature Range
The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated in the
package due to the load drive for all outputs. The quiescent
power is the voltage between the supply pins (VS) times the
quiescent current (IS). Assuming the load (RL) is mid-supply,
then the total drive power is VS/2 × IOUT, some of which is
dissipated in the package and some in the load (VOUT × IOUT).

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other condition s above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
RMS output voltages should be considered. If RL is referenced to
VS- as in single supply operation, the total power is VS × IOUT
.
In single supply with RL to VS- worst case is VOUT = VS/2.
Airflow will increase heat dissipation effectively reducing θJA.
Also, more metal directly in contact with the package leads
from metal traces, through holes, ground, and power planes will
reduce the θJA.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, i.e., θJA is specified
for device soldered in circuit board for surface mount packages.

Maximum Power Dissipation
The maximum safe power dissipation in the ADA4851 package
is limited by the associated rise in junction temperature (TJ) on
the die. At approximately 150°C, which is the glass transition
temperature, the plastic will change its properties. Even
temporarily exceeding this temperature limit may change the

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
