Key Featrues
High-Density Integration: The MAX4936A/MAX4937A integrates eight transmit/receive switches in a single package, optimizing space in high-channel-count systems. This reduces the overall footprint and simplifies PCB design, making it ideal for compact applications like medical and industrial imaging.
Independent Channel Control: With two banks of four channels and independent enable controls (EN1 and EN2), users can selectively activate or deactivate specific channel groups. This enhances flexibility and power efficiency in systems where not all channels are in use simultaneously.
Low On-Impedance with Minimal Bias Current: The switches feature a low 6Ω (typ) on-impedance while consuming only 1.5mA bias current. This ensures efficient signal transmission with minimal power loss, improving overall system performance and energy efficiency.
Grass-Clipping Diodes (MAX4936A Only): The inclusion of low-capacitance anti-parallel diodes allows for effective signal clamping or grass-clipping, reducing noise and enhancing signal integrity in ultrasound and imaging applications.
Wide Bandwidth and Low Noise: With a wide -3dB bandwidth of 100MHz (typ) and low noise (<0.5nV/√Hz), the switches deliver high-fidelity signal transmission, improving image quality and accuracy in medical imaging and ultrasound systems.
