GENERAL DESCRIPTION
The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost,
high speed, rail-to-rail output op amps with ultralow power disables
that are ideal for portable consumer electronics. Despite their low
price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent
overall performance and versatility. The 100 MHz, −3 dB
bandwidth, and 120 V/µs slew rate make these amplifiers well-
suited for many general-purpose, high speed applications.
The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op
amps are designed to operate at supply voltages as low as 2.65 V and up
to 5 V using only 1.4 mA of supply current per amplifier. To further
reduce power consumption, the amplifiers are equipped with a disable
mode that lowers the supply current to less than 1.5 µA maximum,
making them ideal in battery-powered applications.
The ADA4853-1/ADA4853-2/ADA4853-3 provide users with a
true single-supply capability, allowing input signals to extend
200 mV below the negative rail and to within 1.2 V of the positive
rail. On the output, the amplifiers can swing within 200 mV of
either supply rail.With their combination of low price, excellent
differential gain (0.2%), differential phase (0.10°), and 0.5 dB flatness
out to 22 MHz, these amplifiers are ideal for video applications.
The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is
available in a 16-lead LFCSP_VQ, and the ADA4853-3 is available in
both a 16-lead LFCSP_VQ and a 14-lead TSSOP. The ADA4853-1
temperature range is −40°C to +85°C while the ADA4853-2/
ADA4853-3 temperature range is −40°C to +105°C.

device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, θJA is
specified for the device soldered in the circuit board for
surface-mount packages.

Maximum Power Dissipation
The maximum safe power dissipation for the ADA4853-1/
ADA4853-2/ADA4853-3 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
can change the stresses that the package exerts on the die,
permanently shifting the parametric performance of the
amplifiers. Exceeding a junction temperature of 150°C for an
extended period can result in changes in silicon devices,
potentially causing degradation or loss of functionality.
The power dissipated in the package (PD) for a sine wave and a
resistor load is the total power consumed from the supply
minus the load power.
PD = Total Power Consumed − Load Power

RMS output voltages should be considered.
Airflow increases heat dissipation, effectively reducing θJA.
In addition, more metal directly in contact with the package
leads and through holes under the device reduces θJA.
Figure 6 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 6-lead SC70
(430°C/W), the 14-lead TSSOP (120°C/W), and the 16-lead
LFCSP_VQ (63°C/W) on a JEDEC standard 4-layer board. θJA
values are approximations.
