HV2605FG-G

Analog Switches - Special Purpose Overview

The HV2605FG-G is a 16-channel high-voltage analog switch IC from Microchip Technology, housed in a 48-lead LQFP package. It operates with a logic supply voltage (VDD) ranging from 3 V to 5.5 V and supports dual high-voltage supplies (VPP/VNN) such as +40V/-160V, +100V/-100V, or +160V/-40V. The device features a maximum on-resistance of 25 Ω at 5 mA signal current and 10 µA quiescent power dissipation. It includes a 16-bit serial shift register with latches, supporting clock frequencies up to 20 MHz. Operating temperature range is 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Low harmonic distortion design for high-fidelity signal switching
• Integrated 16-bit serial data shift register with latching capability
• Compatible with 3.3V input logic levels for low-voltage control
• Bilateral DMOS switches combined with low-power CMOS logic

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Non-destructive metal flaw detection equipment
• Piezoelectric transducer drivers
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific package variant, as the datasheet notes that the LQFP package is not recommended for new designs and suggests TQFP as an alternative. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure ordering suffixes match the exact pinout and electrical specifications required for the target application circuit.

Analog Switches - Special Purpose Selection Notes

Select this component when low harmonic distortion and high-voltage switching are required under low-voltage control. Compare against the HV2705 if integrated bleed resistors for capacitive loads like piezoelectric transducers are necessary. Verify that the 48-lead LQFP package meets thermal and mechanical constraints, considering the manufacturer's recommendation to use TQFP for new designs.

Analog Switches - Special Purpose Part Context

The HV2605FG-G belongs to the HV2605/HV2705 family of 16-channel low harmonic distortion high-voltage analog switches. These devices are engineered for applications requiring efficient control of high-voltage analog signals using low-power CMOS logic. The FG-G suffix indicates a specific packaging and lead-free configuration within the broader product line.

Analog Switches - Special Purpose Replacement Considerations

The HV2705FG-G is a direct functional substitute that includes integrated bleed resistors. For new designs, consider the HV2605TQ-G which utilizes the recommended TQFP package instead of the LQFP format.
