GENERAL DESCRIPTION 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 opera- tional 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 (AOL) and a 160 dB typical common-mode rejection ratio (CMRR), as shown in Figure 3. The ADHV4702-1 also has a 2 µV/°C maximum input offset voltage (VOS) 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 VCC or VEE voltages. The ADHV4702-1 operates over the −40°C to +85°C industrial temperature range.
