FEATURES
DESCRIPTION

• Compact T/R Switch for Ultrasound
The TX810 provides an integrated solution for a wide
range of ultrasound applications. It is an 8 channel,
• Flexible Programmability
current programmable, transmit/receive switch in a
– 8 Bias Current Settings
small 6mm × 6mm package.
– 8 Power/Performance Combinations
The internal diodes limit the output voltage when high
– Easy Power-Up/Down control
voltage transmitter signals are applied to the input.
• Fast Wake Up Time
While the insertion loss of TX810 is minimized during
receive mode.
• Dual Supply Operation
• Optimized Insertion Loss
Unlike conventional T/R switches, the TX810 contains
a 3-bit interface used to program bias current from
7mA to 0mA for different performance and power
APPLICATIONS
requirements. When the TX810 bias current is set as
• Medical Ultrasound
0mA (i.e., high-impedance mode), the device is
• Industrial Ultrasound
configured as power-down mode. In the
high-impedance mode, TX810 does not add
additional load to high-voltage transmitters. In
addition, the device can wake up from power-down
mode in less than 1µs. With these advanced
programmability features, significant power saving
can be achieved in systems.
