TX810
www.ti.com SLLS996A – SEPTEMBER 2009 – REVISED APRIL 2010 8-Channel, Programmable T/R Switch for Ultrasound
Check for Samples: TX810 FEATURES DESCRIPTION The TX810 provides an integrated solution for a wide
range of ultrasound applications. It is an 8 channel,
current programmable, transmit/receive switch in a
small 6mm Г— 6mm package. 1 2 Compact T/R Switch for Ultrasound
Flexible Programmability
– 8 Bias Current Settings
– 8 Power/Performance Combinations
– Easy Power-Up/Down control
Fast Wake Up Time
Dual Supply Operation
Optimized Insertion Loss The internal diodes limit the output voltage when high
voltage transmitter signals are applied to the input.
While the insertion loss of TX810 is minimized during
receive mode.
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
requirements. When the TX810 bias current is set as
0mA (i.e., high-impedance mode), the device is
configured
as …
