ADI's ADHV4702-1 HS amplifier is packaged in a unity-gain stable precision package that can provide 220V high voltage. The amplifier provides high input impedance, low input bias current, low drift, low input offset voltage, and low noise, making it suitable for demanding applications. The next-generation architecture allows the device to operate with �� 110V symmetrical dual power supplies, asymmetric dual power supplies, or a single 220V power supply. This device is ideal for applying voltage in precision biasing and control applications. The amplifier is packaged in a 12-lead 7mm x 7mm LFCSP with EPAD and complies with International Electrotechnical Commission (IEC) 61010-1 creepage and clearance standards. Copper EPAD provides a low thermal resistance path to improve heat dissipation. EPAD also provides high-voltage isolation, allowing it to be safely connected to the 0V ground plane even with VCC or VEE voltages. The device operates over the -40C to + 85C temperature range.
