Introduction
ADHV4702-1 is a high voltage (220 V), unity gain stable precision operational amplifier. ADI’s next-generation proprietary semiconductor process and innovative architecture enable this precision operational amplifier to be powered by ±110 V symmetrical dual power supplies, asymmetrical dual power supplies, or 220 V single power supplies.
The industry’s first 220 V precision operational amplifier
ADHV4702-1 has a typical open-loop gain of 170 dB (AOL) And a typical common-mode rejection ratio (CMRR) of 160 dB. The maximum input offset voltage of ADHV4702-1 (VOS) The drift is 2 µV/°C, and the input voltage noise is 8 nV/√Hz. The excellent DC accuracy of the ADHV4702-1 complements the excellent dynamic performance, with a small signal bandwidth of 10 MHz and a slew rate of 74 V/µs. The typical output current of ADHV4702-1 is 20 mA. In addition, it also has some unique features, such as adjustable power supply current, boost circuit and EPAD pad because of its internal isolation and can be flexibly biased. These features make it an ideal high-voltage solution for various applications.
