110V 1A功率运算放大器配备数字控制110V 1A power op-amp has digital control
➀ 美国ADI公司发布ADHV4710高压大电流运算放大器，支持±55V电源和±1A输出，配备19MHz SPI数字接口，可编程设置电流、电压及热保护限制；
➀ 该放大器采用改进信号路径，支持大容性负载，可配置高/低增益模式，并通过动态偏置电流提升大信号带宽（80V峰峰值下带宽达2.3MHz）；
➂ 适用于功率放大器、可编程电源、压电驱动器等场景，需额外5V参考电压和散热器，最高可处理19W功耗，工作温度范围-40°C至+85°C。
➀ Analog Devices introduces the ADHV4710, a ±55V/±1A power op-amp with digital control via a 19MHz SPI interface for setting parameters like current limits and thermal thresholds;
➀ The amplifier supports large capacitive loads, configurable gain modes (high/low), and adaptive bias current for improved large-signal bandwidth (2.3MHz at 80Vp-p);
➂ Designed for applications such as power amplifiers, programmable power supplies, and piezoelectric drivers, requiring a 5V reference and heatsink for thermal management up to 19W.
