ADA4700-1

100 V, Precision Operational Amplifier
Manufactured by:

Product Details

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.

APPLICATIONS

  • Automated and bench top test equipment
  • High-voltage regulators and power amplifiers
  • Data acquisition and signal conditioning
  • Piezo drivers and predrivers
  • General-purpose current sensing

I'm always happy with my ADI products. Unfortunately, I have trouble finding a use for them right away, but i always have projects in the works

For some reason I didn't realize that the evaluation board I ordered would not be populated with any parts. So I have this very nice well-made board, but I will have to populate it myself before I can see how the part I was interested in works. Most evaluation boards I buy are fully functional. Maybe I just didn't pick the product I really needed, but to me it is a little unusual to supply just an evaluation board with no parts. Anyway, if I ever get it built I will come back and say what I think of the part. For now, that project is on hold.

A bare boad still waiting to be populated.
