GENERAL DESCRIPTION

The ADA4700-1 is a high voltage precision operational amplifier

with a wide operating voltage (±5 V to ±50 Vꢀ 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

(SNRsꢀ.

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 (PCBꢀ.

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.
