1 Introduction

This user's guide describes the TMUX9832BGAEVM evaluation module (EVM) and the intended use. This
board allows for the quick prototyping and evaluation of TI's TMUX9832ZEH multiplexer. The TMUX9832 is
a 32-channel low harmonic distortion, low resistance, low capacitance, high-voltage, analog switch integrated
circuit (IC) with latch-up immunity. Each device has 32 independently selectable 1:1, single-pole, single-throw
(SPST) switch channels. The device only requires a +5 V analog supply, while still being able to support ±110 V
analog signals. TMUX9832 also integrates bleed resistors on the drain (Dx) pins to discharge capacitive loads,
like piezoelectric transducers.
TMUX9832 is an excellent choice for medical ultrasound imaging and other piezoelectric transducer driver
applications. TMUX9832 integrates cascadable 32-bit shift register with latches for controlling each of the 32
switches. The daisy chain capability allows for many TMUX9832 devices to be controlled without requiring a
separate chip-select for every device. To reduce noise in the signal path, due to potential clock feed-through, the
active low latch enable can be held high while data is loaded into the shift registers.
