8-channel switches provide fast interface for ultrasound imaging

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX4800A/MAX4802A 8-channel, high-voltage, low-charge-injection SPST switches controlled by a fast, 20MHz serial interface.

Designed using Maxim's proprietary, BCDMOS process technology, the devices combine high-voltage, bilateral DMOS switches and low-power CMOS logic, enabling efficient control of high-voltage analog signals with low-voltage control signals.

Additionally, the MAX4800A and MAX4802A support a wide range of high-voltage supplies, including: Vps+/Vps- = +100V/-100V, +185V/-15V, and +40V/-160V. The MAX4802A also integrates 35kilohm bleed resistors to discharge capacitive loads such as piezoelectric transducers, thus saving cost and space by eliminating the need for external bleed resistors.

Applications include next-generation ultrasound imaging and printer applications.

The MAX4800A and MAX4802A are functionally equivalent to the HV2203 and HV2303. Fully specified over the 0°C to +70°C commercial temperature range, the MAX4800A/MAX4802A are available in an industry-standard, 28-pin PLCC package, as well as 48-pin TQFP and 25-bump CSBGA packages.

Pricing: Starts at $8 (1000-up, FOB USA).
Availability: Now.
