HV2707T-C/R8X

Analog Switches - Special Purpose Overview

The HV2707T-C/R8X is a 16-channel high-voltage analog switch manufactured by Microchip Technology. It operates without high-voltage bias supplies, utilizing only a +5V or +6V bias supply while supporting analog signal voltages up to ±100V. The device features an on-resistance of 14Ω typical and 23Ω maximum at 5mA, with a small-signal bandwidth of 100MHz. It includes integrated bleed resistors (20kΩ to 50kΩ) on both sides of the switches to eliminate voltage buildup on capacitive loads. The component is housed in a 48-lead LQFP package (7x7mm) and supports serial control via a 66MHz clock.

Analog Switches - Special Purpose Feature Summary

• Integrated bleed resistors on both switch terminals for piezoelectric load discharge
• High-voltage switching capability up to ±100V using low-voltage bias supplies
• Low harmonic distortion and low charge injection characteristics
• Cascadable serial data register interface for multi-device daisy-chaining

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Non-destructive testing metal flaw detection
• Piezoelectric transducer drivers
• Inkjet printer heads
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix R8X corresponds to the 48-lead LQFP package configuration. Confirm that the 'T' designation indicates tape and reel packaging if required for automated assembly processes. Ensure compliance with RoHS3 specifications as indicated by the 'C' environmental code. Cross-reference the datasheet revision B documentation for accurate power-up sequences and decoupling capacitor requirements during integration.

Analog Switches - Special Purpose Selection Notes

Select this component when applications require high-voltage signal routing controlled by low-voltage logic without external high-voltage rails. The HV2707 variant is distinct from the HV2708 due to having bleed resistors on both switch terminals rather than just one side. Verify that the 14Ω on-resistance meets the signal integrity requirements for the specific frequency range. Consider the 48-pin LQFP footprint constraints against available PCB real estate.

Analog Switches - Special Purpose Part Context

This device belongs to the HV2607/HV2707/HV2708 family of high-voltage analog switches. It shares pin compatibility with the HV2601/HV2701 and HV2605/HV2705 devices, excluding power supply pins. The primary differentiator within this series is the presence and placement of internal bleed resistors, which are essential for managing charge accumulation on capacitive loads like piezoelectric elements.

Analog Switches - Special Purpose Replacement Considerations

The HV2708 serves as a functional alternative if bleed resistors are required on only one side of the switch. The HV2607 may be used if no bleed resistors are needed. All variants share the same 48-LQFP package and electrical interface, ensuring mechanical and logical interchangeability within the system design.
