MAX4800/MAX4801/MAX4802 19-0631 Rev 2 5/09 Low-Charge Injection, 8-Channel, High-Voltage Analog Switches General Description Features The MAX4800/MAX4801/MAX4802 provide high-volt- Pin-Compatible Replacement for Supertex age switching on eight channels for ultrasonic imaging HV20220 (MAX4800) and printer applications. The devices utilize BCDMOS Pin-Compatible Replacement for Supertex process technology to provide eight high-voltage low- charge-injection SPST switches, controlled by a digital HV20320 (MAX4801) interface. Data is clocked into an internal 8-bit shift reg- Pin-Compatible Replacement for Supertex HV232 ister and retained by a programmable latch with enable (MAX4802) and clear inputs. A power-on reset function ensures that all switches are open on power-up. Flexible High-Voltage Supplies Up to V - V = PP NN 200V The MAX4800/MAX4801/MAX4802 operate with a wide range of high-voltage supplies including: V /V = PP NN Low-Charge Injection, Low-Capacitance 22 +100V/-100V, +185V/-15V, and +40V/-160V. The digital Switches interface operates from a separate V supply from DD DC to 10MHz Analog-Signal Frequency Range +2.7V to +13.2V. Digital inputs DIN, CLK, LE, and CLR are +13.2V tolerant, independent of the V supply DD -77dB Off Isolation at 5MHz voltage. The MAX4802 provides integrated 35k bleed resistors on each switch terminal to discharge capaci- Low 10A Quiescent Current tive loads. Integrated Bleed Resistors (MAX4802) The MAX4800 and MAX4802 are drop-in replacements Available in PLCC, TQFP, and CSBGA Packages for the Supertex HV20220 and HV232. The devices are available in the 48-pin TQFP, 26-bump CSBGA, and 28- pin PLCC packages. The MAX4801 is a drop-in replacement for the Supertex HV20320 and is available in the 28-pin PLCC package. All devices are specified for the commercial 0C to +70C temperature range.
