1 Introduction
The TX810 is an 8-channel, current-programmable, low-noise, transmit/receive switch. It is capable of
operating with ±5-V or +10-V/0-V power supplies. The TX810 provides a highly integrated solution for a
wide range of ultrasound system applications. The TX810EVM (Figure 1) offers a means to evaluate the
functionality and performance of the device.

1.1 Functionality
Figure 2 is the top diagrammatic view of the EVM. The EVM has eight inputs and eight outputs. The bias
current is controlled by the dip switch (S1). The bias current also can be controlled by an external
controller through the J42 header. S1 and J42 are mutually exclusive;; only one of them can be used, the
other must be open. The power supply is connected through J41 header or P1.
