MAX4189EEE+T is listed in the Video Amps And Modules range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC AMP CURRENT FEEDBACK 16QSOP. Review the specifications below when checking this part for your BOM.
The MAX4189EEE+T is a triple, low-power, current-feedback video amplifier featuring fast disable/enable times and low switching transients. It operates from +5V single supply or ±2.25V to ±5.5V dual supplies. Optimized for closed-loop gains of +1V/V (0dB) or greater, it provides a 250MHz -3dB bandwidth. The device consumes 1.5mA per amplifier and delivers ±55mA output current. In low-power disable mode, supply current reduces to 450µA per amplifier. It features excellent video specifications including 0.1dB gain flatness up to 30MHz with differential gain and phase errors of 0.07% and 0.02° respectively.
Verify the specific ordering suffix EEE+ against the manufacturer's official documentation to confirm the 16-pin QSOP package and lead-free status. Confirm the operating temperature range of -40°C to +85°C matches system requirements. Ensure the disable control logic thresholds align with the host controller voltage levels before finalizing procurement.
Select this component when a triple amplifier configuration is required for video signal processing at unity gain. The current-feedback architecture supports high slew rates and wide bandwidths essential for high-speed signal integrity. Consider the low-power disable feature if power management during idle states is critical for portable equipment designs.
This part belongs to the MAX4188/MAX4189/MAX4190 family of single/triple, low-glitch, 250MHz current-feedback amplifiers with high-speed disable capabilities. While sharing core technology with the MAX4188 and MAX4190, the MAX4189 is specifically optimized for closed-loop gains of +1V/V or greater, distinguishing its performance profile within the series.
