MAX14805

19-5253; Rev 0; 4/10 16-Channel (Two Banks of 8-Channel), High-Voltage Analog Switches General Description The MAX14805/MAX14806 provide high-voltage switching on 16 channels for ultrasonic imaging. Both devices are ideal for the following applications: banks selection in biplane or triplane ultrasound probes and relays replacement. The devices utilize 200V process technology to provide sixteen high-voltage, low-charge injection SPST switches, controlled by a digital interface. The MAX14805/MAX14806’s output switches are configured as two sets of eight SPST analog switches. The switches are controlled by two input logic controls, DIN1 and DIN2 (respectively for switch 0 to 7 and switch 8 to 15). The MAX14806 features integrated 40kI bleed resistors on each switch terminal, which help to reduce voltage buildup in capacitive loads such as piezoelectric elements. The MAX14805/MAX14806 operate with a wide range of high-voltage supplies, including VPP/VNN = +100V/-100V, +200V/0V, and +40V/-160V. The digital interface operates from a separate VDD supply from +2.7V to +5.5V. Digital inputs DIN1, DIN2, and LE operate on the VDD supply voltage. The MAX14805CCM+ is a drop-in replacement for the Supertex HV2631. The MAX14806CCM+ is a drop-in replacement for the Supertex HV2731. Both devices are available in the 48-pin, TQFP package and are specified for the extended -40NC to +85NC temperature range.

The MAX14805/MAX14806 operate with a wide range of high-voltage supplies, including VPP/VNN = +100V/-100V, +200V/0V and +40V/-160V. The digital interface operates from a separate VDD supply from +2.7V to +5.5V. Digital inputs DIN1, DIN2, and LE operate on the VDD supply voltage. The MAX14805CCM+ is a drop-in replacement for the Supertex HV2631. The MAX14806CCM+ is a drop-in replacement for the Supertex HV2731. The MAX14805/MAX14806 allow a peak-to-peak analog signal range from VNN to (VPP - 10V). During power-up and power-down, all analog switch inputs (SW_) must be unconnected or satisfy VNN P VSW_ P VPP. The MAX14805/MAX14806 allow a wide range of highvoltage supplies. The devices operate with VNN from -160V to 0V and VPP from +40V to (VNN + 220V). When VNN is connected to GND (single-supply applications), the devices operate with VPP up to +200V. The VPP and VNN high-voltage supplies are not required to be symmetrical, but the voltage difference (VPP - VNN) must not exceed 230V. The MAX14806 features integrated 40kI bleed resistors to discharge capacitive loads such as piezoelectric transducers. Each analog switch terminal is connected to GND with a bleed resistor. DIN1/DIN2 control the on/off state of the analog switches. DIN1 controls SW0–SW7 and DIN2 controls SW8–SW15 (see Table 1 and Figure 2). DIN1 and DIN2 operate on the VDD supply voltage. Drive LE logic-low to latch DIN1/DIN2 data input (see Figure 2). Drive LE logic-high to hold data. The LE input operates on the VDD supply voltage. High-Voltage Supplies Bleed Resistors (MAX14806) Data Input (DIN1/DIN2) Latch Enable (LE) Applications Information For medical ultrasound applications, see Figures 3 and 4. The MAX14805/MAX14806 do not require special sequencing of the VDD, VPP, and VNN supply voltages; however, analog switch inputs must be unconnected or satisfy VNN P VSW_ P VPP during power-up and powerdown. Bypass VDD, VPP, and VNN to GND with a 0.1FF ceramic capacitor as close as possible to the device.
