The ADHV4702-1 is a high voltage (220 V), unity-gain stable precision operational amplifier. The ADHV4702-1 offers high input impedance with low input bias current, low input offset voltage, low drift, and low noise for precision demanding applications. The next generation of proprietary semiconductor processes and innovative architecture from Analog Devices, Inc., enable this precision operational amplifier to operate from symmetrical dual supplies of ±110 V, asymmetrical dual supplies up to 220 V span, or a single supply up to 175 V.

For precision performance, the ADHV4702-1 has a 170 dB typical open-loop gain (A_OL) and a 160 dB typical common-mode rejection ratio (CMRR). The ADHV4702-1 also has a 2 μV/°C maximum input offset voltage (V_OS) drift and an 8 nV/√Hz input voltage noise.

The exceptional dc precision of the ADHV4702-1 is complemented by excellent dynamic performance with a small signal bandwidth of 10 MHz and a slew rate of 74 V/μs. The ADHV4702-1 has an output current of 20 mA typical.

The ADHV4702-1 offers high voltage input common-mode swing as well as high voltage output swing, enabling precision high voltage use cases such as high-side current sensing.

The ADHV4702-1 is available in a 12-lead, 7 mm × 7 mm lead frame chip scale package (LFCSP) with an exposed pad (EPAD) compliant to international electrotechnical commission (IEC) 61010-1 creepage and clearance standards. The copper EPAD provides a low thermal resistance path to improve heat dissipation and features high voltage isolation, allowing it to be safely connected to a 0 V ground plane regardless of V_CC or V_EE voltages. The ADHV4702-1 operates over the −40°C to +85°C industrial temperature range.

Applications

High-side current sensing
Automated test equipment
High voltage drivers
Piezotransducers
Digital-to-analog converter (DAC) output buffers
Light detecting and ranging (LiDAR), avalanche photodiode (APD), single photon avalanche diode (SPAD) biasing

Product Details

This user guide describes the EVAL-ADHV4702-1CPZ board, which helps users evaluate the ADHV4702-1 offered in a 7 mm × 7 mm, 12-lead lead frame chip scale package (LFCSP) with an exposed pad at the bottom. The evaluation board provides a platform for quick and easy evaluation of the ADHV4702-1. Figure 1 in the user guide shows the top side of the evaluation board. Figure 2 shows the bottom side of the board with the large exposed copper area for attaching a heat sink to provide additional thermal management.

The evaluation board is a 6-layer board designed to minimize leakage currents with its guard ring feature. It accepts Subminiature Version A (SMA) and Subminiature Version B (SMB) edge mounted connectors on the inputs for easy connection to test equipment or other circuitry.

Full specifications of the ADHV4702-1 and details of the device operation and application circuit configurations and guidance can be found in the ADHV4702-1 data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with the user guide, especially when powering up the evaluation board for the first time.

For safety, the EVAL-ADHV4702-1CPZ board is covered top and bottom with acrylic plastic guards to reduce the risk of inadvertent contact with high voltage. Do not operate the board without these guards in place. If the guards must be removed to adjust jumpers or change component values, disconnect the board from the power supply before removing guards, and replace the guards before powering up again.

Warning: this high voltage evaluation board contains exposed metal carrying lethal voltages when under power. Take all necessary steps to protect users during operation. For full precautions when using this high voltage evaluation board, see the High Voltage Evaluation Board section of the user guide.
