HV2601FG-G-M931

Analog Switches - Special Purpose Overview

The HV2601FG-G-M931 is a low-charge injection, 16-channel high-voltage analog switch IC manufactured by Microchip Technology. It utilizes High-Voltage CMOS technology to combine bilateral DMOS switches with low-power CMOS logic. The device operates with flexible supply voltages, supporting VPP from +40V to +200V and VNN from -40V to -160V. It features a maximum on-resistance of 38 Ohms at VPP=+40V/VNN=-160V and a small signal bandwidth of 50MHz. The unit is housed in a 48-LQFP (7x7) package and supports a data shift clock frequency up to 20MHz.

Analog Switches - Special Purpose Feature Summary

• Low charge injection design for precision signal switching
• High-voltage operation with flexible dual supply configurations
• Serial data register with latches for efficient control
• Compatible with 3.3V input logic levels

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• NDT metal flaw detection equipment
• Piezoelectric transducer drivers
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific M931 suffix against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the 48-LQFP package dimensions with recommended land patterns to prevent soldering defects during production.

Analog Switches - Special Purpose Selection Notes

Select this component when high-voltage analog switching is required with minimal charge injection artifacts. Verify that the operating voltage range (+40V to +200V) aligns with the system's power supply architecture. Consider the 48-LQFP package constraints if space is limited, noting the manufacturer's recommendation to use TQFP for new designs.

Analog Switches - Special Purpose Part Context

This part belongs to the HV2601/HV2701 family of low-charge injection analog switches. While the HV2701 variant includes integrated bleed resistors for capacitive loads, the HV2601 does not. Both share identical pinouts and electrical characteristics except for the bleed resistor feature. The FG-G-M931 designation specifies the lead-free, tape-and-reel packaging configuration.

Analog Switches - Special Purpose Replacement Considerations

The datasheet explicitly recommends using the TQFP package as an alternative to the LQFP package for new designs due to legacy status. Verify pin compatibility if substituting with other members of the HV2601/HV2701 family.
