GENERAL DESCRIPTION The ADA4851-1 is a low cost, high speed, voltage feedback
rail-to-rail output op amp. Despite its low price, the ADA4851-1
provides excellent overall performance and versatility. The
130 MHz −3 dB bandwidth and 800 V/µs slew rate make this
amplifier well-suited for many general-purpose, high speed
applications.
The ADA4851-1 is designed to operate at supply voltages as low as
3 V and up to 5 V using only 2.5 mA of supply current. To further
reduce power consumption, the amplifier is equipped with a
power-down mode, which lowers the supply current to 0.2 mA.
The ADA4851-1 provides users with a true single-supply
capability, allowing input signals to extend 200 mV below the
negative rail and to within 2 V of the positive rail. On the output,
the amplifier can swing within 70 mV of either supply rail.
With its combination of low price, excellent differential gain
(0.04%), differential phase (0.06º), and 0.1dB flatness out to
14 MHz, this amplifier is ideal for consumer video applications.
The ADA4851-1 is available in a SOT-23-6 package and is
designed to work in the extended temperature range (−40°C
to +125°C).

Table 3. ABSOLUTE MAXIMUM RATINGS
Table 4. Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions 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.
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.
Table 5. Thermal Resistance
Maximum Power Dissipation The maximum safe power dissipation for the ADA4851-1 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 changes its properties. Even temporarily
exceeding this temperature limit may change the stresses that
the package exerts on the die, permanently shifting the
parametric performance of the ADA4851-1. Exceeding a
junction temperature of 150°C for an extended period of time
can result in changes in silicon devices, potentially causing
degradation or loss of functionality.
The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated in the die
due to the ADA4851-1 drive at the output. The quiescent power
is the voltage between the supply pins (VS) times the quiescent
current (IS).
PD = Quiescent Power + (Total Drive Power − Load Power)

RMS output voltages should be considered. If RL is referenced to
−VS, as in single-supply operation, the total drive power is VS ×
IOUT. If the rms signal levels are indeterminate, consider the
worst case, when VOUT = VS/4 for RL to midsupply. SDRIVP4/+×=
In single-supply operation with RL referenced to −VS, worst case
is VOUT = VS/2.
Airflow increases heat dissipation, effectively reducing θJA.
Also, more metal directly in contact with the package leads and
exposed paddle from metal traces, through holes, ground, and
power planes reduce θJA.
Figure 3 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the SOT-23-6
(170°C/W) package on a JEDEC standard 4-layer board. θJA
values are approximations.
