Octal T/R switches from Maxim for ultrasound imaging

Maxim Integrated Products has released the MAX4936/MAX4937, a fully integrated octal high-voltage transmit/receive (T/R) switches. These switches integrate clamping diodes to isolate the low-voltage receive path from the high-voltage transmit path. Maxim's integrated solution uses > 50% less board space. The MAX4936/MAX4937 are suggested for ultrasound imaging and industrial flaw-detection probes.

The MAX4936/MAX4937 feature eight individually programmable switches controlled through an SPI interface with a 12-bit shift register and transparent latch. These features simplify device operation when updating the states of the T/R switch; they ensure that all switches are off at power-on; and they reduce noise due to clock feedthrough.

Package: 5mm x 11mm, 56-pin TQFN

Operating temperature range: 0°C to +70°C

Price: Start at US$12.00
