ADA4700-1:  100 V, Precision Operational Amplifier

Product Details

Product Status:Recommended for New Designs

The 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 predriver 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.
