HV2631FG-G

Analog Switches - Special Purpose Overview

The HV2631FG-G is a 16-channel high voltage analog switch IC manufactured by Microchip Technology, utilizing HVCMOS technology. It features two independent banks of eight single-pole single-throw (SPST) switches controlled by DIN1 and DIN2 logic inputs. The device supports a maximum differential supply voltage of 220V with a typical on-resistance of 22Ω at VPP=50V and VNN=-170V. Logic control operates on 3.0V to 5.5V supplies, ensuring compatibility with standard CMOS logic levels. The component is housed in a 48-lead LQFP package with a 0.50mm pitch.

Analog Switches - Special Purpose Feature Summary

• HVCMOS technology enables efficient control of high voltage analog signals using low power CMOS logic
• Dual bank architecture allows independent control of sixteen channels via separate logic inputs
• High off-isolation characteristics minimize signal leakage between disconnected channels
• Low parasitic capacitance and excellent noise immunity support high frequency operation

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Non-destructive evaluation equipment
• High voltage signal routing in test and measurement instruments

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix FG-G to confirm the 48-lead LQFP package configuration and RoHS compliance status. Ensure that the procurement documentation explicitly references the Microchip or Supertex datasheet for the HV2631 series to validate technical specifications against the requested part number before finalizing orders.

Analog Switches - Special Purpose Selection Notes

Select this component when applications require switching voltages up to 220V with low distortion and high isolation. The dual-bank control structure simplifies circuit design for multiplexing large arrays of sensors or transducers. Verify that the required logic supply voltage falls within the 3.0V to 5.5V range and that the thermal dissipation requirements fit within the 1.2W limit of the LQFP package.

Analog Switches - Special Purpose Part Context

The HV2631 belongs to the Supertex HV26xx family of high voltage analog switches, which were acquired by Microchip Technology. This series is designed specifically for demanding applications requiring robust high voltage switching capabilities integrated with standard low voltage digital control interfaces. The FG suffix denotes the specific surface mount package variant used in modern PCB assemblies.
