Chapter 1. Product Overview
1.1 INTRODUCTION
HV2903 Analog Switch Evaluation Board (ADM00795) works with HV MUX Controller
Board (ADM00825) to provide 32-channel, high-voltage (HV) analog switches, without
HV supplies demonstration, including basic switch ON/OFF operation and 2:1 MUX
operation, with two built-in MD1822 and TC6320 pulser circuits.
1.2 HV2903 INTEGRATED CIRCUIT – DESCRIPTION
The HV2903 device is a no HV bias, low-harmonic distortion, low-charge injection, con-
sisting of 32-channel, HV analog switches. It is designed for use in applications requir-
ing high-voltage switching controlled by low-voltage control signals, such as medical
ultrasound imaging, driving piezoelectric transducers and printers. The typical 10 on
resistance analog switch can pass the analog pulse signal up to ±3A of current at
±100V, without high-voltage supplies such as ±100V. It requires only ±6V or ±5V for the
ON/OFF switch operation and 3.3V for logic operation.
The HV2903 device has two modes of operation: Individual Switching mode and Bank
Switching mode. The user can select the mode with the MODE pin logic input. The 32
analog switches can be controlled individually through a digital interface when the
MODE input is high (Individual Switching mode). The digital interface clock operates up
to 66 MHz. All 16 even switches and all 16 odd switches can be controlled together
through simple 2-input logic when the MODE input is low (Bank Switching mode).
The Standby mode is used to decrease power consumption during idle state. When
STBY logic input is low, the HV2903 device operates in Standby mode and consumes
very low current. When STBY logic input is high, the device operates normally.
1.3 HV2903 ANALOG SWITCH EVALUATION BOARD – FEATURES

1.4 HV2903 ANALOG SWITCH EVALUATION BOARD – FUNCTIONAL
DESCRIPTION
The HV2903 Analog Switch Evaluation Board can control the HV2903 operation and
built-in pulsers that are connected to two 2:1 MUX switches for demonstration. Four
switch outputs of two 2:1 MUX have SMA connectors and the user can connect four
transducer elements. The other side of the 2:1 MUX is connected to two built-in
MD1822 and TC6320 pulsers. The HV2903 Analog Switch Evaluation Board can drive
four transducer elements with 5 MHz, ±100V pulse signals.
The evaluation board features one HV2903/AHA 12x12x1.2 mm 132-Lead TFBGA
packaged integrated circuit, two MD1822K6-G 3x3x1 mm 16-Lead QFN packaged
integrated circuits, and four TC6320K6-G 4x4x1 mm 8-Lead DFN packaged NMOS
and PMOS pair integrated circuits.
The HV2903 Analog Switch Evaluation Board uses two high-speed 20-signal pair
carrying-capable, right-angle backplane connectors, which are designed to work with
the Microchip HV MUX Controller Board (ADM00825) as a control signal source.
The HV MUX Controller Board has an FPGA that generates pulser waveform and
logic control signals, and a USB bridge IC that connects the control board to a PC. By
means of a Microsoft® Windows® driver and GUI, the user can control the HV2903
device and two built-in pulsers.
Four switch terminals, consisting of two MUX configurations on the PCB, have SMA
connectors to which the user can connect loads. Jumpers close to SMA connectors
are for connecting the on-board dummy R-C load (330 pF//2.5 k) optionally to the
pulser output.

2.6.2 HV2903 Analog Switch Evaluation Board GUI Description
Figure 2-9 displays a screen capture of the GUI. Every item indicated by circled
numbers is explained below the figure. The selection of the check box, binary data in
the DIN entry box, and number in Pulses and TOFF entry box are just settings. They do
not change the operation of the HV2903 device and built-in pulsers immediately. By
clicking Set HV MUX, Start and Stop buttons, the control data set by the user in the
GUI changes operation of HV2903 and turns on/off the built-in pulsers in the HV2903
Analog Switch Evaluation Board. See the explanation for each corresponding item.
FIGURE 2-9: HV MUX CONTROLLER BOARD GUI SCREEN CAPTURE
1. Initialize HV MUX Controller: When clicked, the GUI starts the initialization of
FPGA on the HV MUX Controller, and the communication between the GUI and
the HV MUX Controller. If there is no error, the “Initialization Complete” text is
displayed in the Message window.
2. STBY: When checked, the STBY logic input is set to low and HV2903 is set to
operate in Standby mode to decrease power consumption. When unchecked, the

4. DIN: 32-bit data entry boxes. Each bit in the boxes is related to each analog
switch. If data entry is ‘1’, the associated switch is set to on. If data entry is ‘0’,
the associated switch is set to off.
5. CLR: When checked, the CLR logic input is set to high and all the switches of
HV2903 are set to off. When unchecked, the CLR logic input is set to low and the
32 switches of HV2903 are set to ON/OFF states, according to the DIN data
entry.
6. EN: When checked, the EN logic input is set to high and HV2903 is set to active
for Bank Switching mode. When unchecked, the EN logic input is set to low and
all the switches are set to off.
