Overview
The ADHV4702-1BCPZ is a high voltage, unity-gain stable precision operational amplifier manufactured by Analog Devices Inc. This operational amplifier is designed to operate over a wide range of voltages, including symmetrical dual supplies of ±110 V, asymmetrical dual supplies up to 220 V, and a single supply up to 175 V. It features high input impedance, low input bias current, low input offset voltage, low drift, and low noise, making it suitable for precision-demanding applications.
The ADHV4702-1BCPZ leverages next-generation proprietary semiconductor processes and innovative architecture to achieve exceptional dc precision and dynamic performance. It is available in a 12-lead, 7 mm × 7 mm lead frame chip scale package (LFCSP) with an exposed pad (EPAD) that complies with international electrotechnical commission (IEC) 61010-1 creepage and clearance standards.
