            ADHV4702-1 24 V to 220 V Precision Op-Amp
                    Analog Devices' op-amp is ideal for high-side current-sensing, high-voltage drivers, and DAC output buffers
    

Image of Analog Devices' ADH4702-1 Precision Op-Amp ADI's ADHV4702-1 is a high-voltage (220 V), unity-gain, stable precision op-amp and offers high-input impedance with low-input bias current, low-input offset voltage, low drift, and low noise for precision-demanding applications. The proprietary semiconductor processes and innovative architecture from ADI enable this precision op-amp to operate from symmetrical dual supplies of ±110 V, asymmetrical dual supplies, or a single supply of 220 V.

The ADHV4702-1 offers high-voltage input common-mode swing and high voltage output swing enabling precision high-voltage use cases such as high-side current-sensing. The device is ideal for forcing a voltage in precision bias and control applications.

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 the V_CC or V_EE voltages. The ADHV4702-1 operates over the -40°C to +85°C industrial temperature range.
