16 channel high voltage analog switches

16 November 2005 Analogue, Mixed Signal, LSI

Supertex has introduced two new low charge injection, 16 channel, 200 V analog switch ICs. The HV2601 and HV2701 are well-suited for applications that require high voltage switching controlled by low voltage signals, such as in medical ultrasound imaging and nondestructive metal flaw detection. The HV2701 also features integrated bleed resistors that minimise noise and reduce capacitive coupling. The ICs feature very low quiescent current of 10 μA. Other features include 22 Ω switch resistance that minimises return signal attenuation, serial shift register control to reduce I/O connections, and up to 200 V operating voltage for higher transmit voltages, providing deeper imaging capability. The RoHS HV2601 and the HV2701 come in 48 lead TQFP packages.
