HV2705TQ-G-M931

Analog Switches - Special Purpose Overview

The HV2705TQ-G-M931 is a 16-channel high-voltage analog switch integrated circuit manufactured by Microchip Technology. It features low harmonic distortion and operates with flexible supply voltages, supporting combinations such as VPP/VNN of +40V/-160V, +100V/-100V, or +160V/-40V. The device includes integrated bleed resistors on the outputs to eliminate voltage build-up on capacitive loads. It utilizes a cascadable serial data register with latches for control via low-voltage logic signals. The component is housed in a 48-lead TQFP package.

Analog Switches - Special Purpose Feature Summary

• Integrated bleed resistors on all outputs to discharge capacitive loads
• Low harmonic distortion performance suitable for precision signal switching
• Compatible with 3.3V input logic levels for simplified interface
• Cascadable serial data register with latches for efficient control

Analog Switches - Special Purpose Applications

• Medical Ultrasound Imaging
• Non-destructive Metal Flaw Detection
• Piezoelectric Transducer Drivers
• Optical MEMS Modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and supply voltage configurations before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Analog Switches - Special Purpose Selection Notes

Select this component when high-voltage analog switching with low distortion is required. The integrated bleed resistors make it distinct from similar models lacking this feature. Verify that the 48-lead TQFP package fits the design constraints. Confirm that the logic supply voltage range supports the system's control interface requirements.

Analog Switches - Special Purpose Part Context

This part belongs to the HV2605/HV2705 family of 16-channel low harmonic distortion high-voltage analog switches. The HV2705 variant specifically distinguishes itself by including integrated output bleed resistors, whereas the HV2605 does not. Both share identical pinouts and control logic but differ in internal output stage configuration.

Analog Switches - Special Purpose Replacement Considerations

The HV2605TQ-G-M931 is a functional substitute if integrated bleed resistors are not required. Verify that the replacement part matches the 48-lead TQFP package dimensions and pinout exactly to ensure mechanical and electrical compatibility without PCB redesign.
