GENERAL DESCRIPTION
The ADA4700-1 is a high voltage precision operational amplifier
with a wide operating voltage (±5 V to ±50 V) and relatively
high output current drive available as a single op amp in an
SOIC package. It combines low power consumption, high
bandwidth, and a slew rate with unity-gain stability and phase
inversion free performance. The ability to swing near rail-to-rail
at the output enables designers to maximize signal-to-noise ratios
(SNRs).
The ADA4700-1 is specified over the industrial temperature
range of −40°C to +85°C and includes an on-board thermal
shutdown at 165°C internal junction temperature as well as an
internal current limit for safety. The ADA4700-1 is available in
a thermally enhanced, 8-lead SOIC package that uses a small
exposed metal pad on the bottom of the package to allow the
customer to heat sink the part to the printed circuit board (PCB).
For proper operation, the exposed pad must be connected to V−.
The ADA4700-1 is designed for applications requiring both ac and
precision dc performance, making the ADA4700-1 useful in a
wide variety of applications, including high voltage test equipment
and instrumentation, high voltage regulators and power amplifiers,
power supply control and protection, and as an amplifier or buffer
for transducers with wide output ranges. It is particularly well
suited for high intensity LED testing applications where it provides
highly accurate voltage and current feedback as well as a predriver
to provide accurate voltage and/or current sourcing stimulus to
the LED string under test.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress

other conditions above those indicated in the operational

device reliability.

change in the stresses exerted on the die by the package.
Exceeding a junction temperature of 175°C for an extended
period can result in device failure.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by a plastic
encapsulated package is limited by the junction temperature.
The maximum safe junction temperature for plastic encapsulated
devices, as determined by the glass transition temperature of the
plastic, is approximately 150°C. Exceeding this limit temporarily
