ADHV4702-1BCPZ

Overview

The ADHV4702-1BCPZ is a high voltage, unity-gain stable precision operational amplifier manufactured by Analog Devices Inc. It operates from symmetrical dual supplies of ±12 V to ±110 V, asymmetrical supplies up to 220 V span, or single supplies up to 175 V. Key electrical characteristics include a typical open-loop gain of 170 dB, a common-mode rejection ratio of 160 dB, and a small signal bandwidth of 10 MHz. The device features a maximum input offset voltage of 1 mV with a drift of 2 µV/°C, a slew rate of 74 V/µs, and an output current capability of 20 mA. It is housed in a 12-lead, 7 mm × 7 mm lead frame chip scale package (LFCSP) compliant with IEC 61010-1 spacing standards.

Procurement Notes

Verify the specific ordering suffix BCPZ against official Analog Devices documentation to confirm package type and compliance details. Ensure that procurement channels provide valid traceability for the LFCSP package. Confirm that the component meets all relevant safety and isolation standards required for high-voltage applications before finalizing orders.

Selection Notes

Select this component for applications requiring high voltage precision amplification with wide dynamic range. Consider the 10 MHz bandwidth and 74 V/µs slew rate for fast signal processing. Evaluate the thermal management requirements due to the exposed pad design. Verify compatibility with the intended power supply configuration, whether symmetrical or asymmetrical, to ensure optimal performance within the specified operating temperature range.

Part Context

The ADHV4702-1 belongs to the family of high voltage precision operational amplifiers from Analog Devices. It utilizes proprietary semiconductor processes to achieve high input impedance and low noise. The device is designed for demanding environments where standard op-amps cannot operate due to voltage limitations. Its architecture supports both precision DC measurements and high-speed AC signal handling in high voltage domains.
