Analog Devices ADA4700-1 Operational Amplifier


High-voltage, precision, single-channel operational amplifier from Analog Devices

The Analog Devices ADA4700-1 is a high-voltage, precision, single-channel operational amplifier with a wide operating voltage range (±5 V to ±50 V) and relatively high output current drive. Its advanced design combines low power (170 mW for a ±50 V supply), high bandwidth (3.5 MHz), and a high 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 designed for applications requiring both AC and DC precision 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 pre-driver to provide accurate voltage and/or current sourcing stimulus to the LED string under test.

The ADA4700-1 is specified over the industrial temperature range of −40°C to +85°C and includes thermal regulation at a junction temperature greater than 145°C and an integrated current limit. The ADA4700-1 is available in a thermally-enhanced, 8-lead SOIC package with an exposed pad.
