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 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.

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. may cause a shift in the parametric performance due to a 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 Package Type 8-Lead SOIC_N_EP (RD-8-2) ESD CAUTION 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 Rev.
