MAX4800A, MAX4802A Low-Charge-Injection, 8-Channel, High-Voltage Analog Switches with 20MHz Serial Interface

Description

The MAX4800A/MAX4802A provide high-voltage switching on eight channels for ultrasonic imaging and printer applications. The devices utilize BCDMOS process technology to provide eight high-voltage low-charge-injection SPST switches, controlled by a 20MHz serial interface. Data is clocked into an internal 8-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up.

The MAX4800A/MAX4802A operate with a wide range of high-voltage supplies including: V_PP/V_NN = +100V/-100V, +185V/-15V, and +40V/-160V. The digital interface operates from a separate V_DD supply from +2.7V to +6V. Digital inputs DIN, CLK, active-low LE, and CLR are +6V tolerant, independent of the V_DD supply voltage. The MAX4802A provides integrated 35kΩ bleed resistors on each switch terminal to discharge capacitive loads.

The MAX4800A/MAX4802A are drop-in replacements for the Supertex HV22C3 and HV2303. The devices are available in the 48-pin TQFP, 26-bump CSBGA, and 28-pin PLCC packages. All devices are specified for the commercial 0°C to +70°C temperature range.
