MAX4936CTN+

The MAX4936CTN+ is an octal high voltage transmit/receive (T/R) switch in 56 pin TQFN package. This T/R switch is based on diode bridge topology and amount of current in diode bridges can be programmed through SPIK interface. It has latch clear input to asynchronously turn off all T/R switches and put the device into low power shutdown mode. The MAX4936 includes T/R switch and grass clipping diodes which performs both transmit and receive operations. The device transmit path is low impedance during high voltage transmit and high impedance during low voltage receive, providing isolation between transmit and receive circuitry. The high voltage transmit path is high bandwidth, low distortion and low jitter. The receive path for the device is low impedance during low voltage receive and high impedance during high voltage transmit, providing protection to receive circuitry. The low voltage receive path is high bandwidth, low noise, low distortion and low jitter.

• 2.7V to 5.5V positive analogue supply voltage and -5.5 to 2.7V negative analogue supply voltage
• Operating temperature range from 0°C to 70°C
• Integrated T/R switches significantly reduces component count while reducing power
• Low power, low impedance (5ohm) with 1.5mA bias current
• Low noise of less than 0.5nV/√Hz with 1.5mA bias current
• Wide -3dB bandwidth of 65MHz and reverse recovery time of 450ns
• Easy programming with SPI interface
• High density (8 channels per package)
• Global shutdown control (CLR) and low voltage receive path with high voltage protection
• Low voltage isolation, high voltage protection and output clamp diodes for receiver protection
