With an 8 GHz gain bandwidth product and 17,500 V\/\u00b5s slew rate, it provides unprecedented usable bandwidth from DC to 2 GHz. It is ideal for single-ended-to-differential (SE-DE) conversion when driving high-speed ADCs, generating extremely low second- and third-order distortion. The device consumes only 275 mW at 5V and includes a power-down feature.","working_principle":"The LMH5401 operates through four key subsystems: (1) Differential Input Stage: A high-impedance differential input pair with 1.25 nV\/\u221aHz noise density accepts single-ended or differential signals. The VOCM pin sets the output common-mode voltage to match ADC requirements. (2) Gain Stage: A voltage-feedback architecture provides 8 GHz GBP with programmable gain via external resistors. The device supports both SE-DE and DE-DE modes. (3) Output Stage: A low-distortion differential output driver achieves HD2 of -104 dBc and HD3 of -96 dBc at 100 MHz, capable of driving 200\u03a9 loads directly. (4) Power Management: A PD (power-down) pin reduces supply current when the amplifier is not needed, and the device operates from single 3.3V to 5V or dual supplies.","pin_description":"
