HV2601TQ-G

Analog Switches - Special Purpose Overview

The HV2601TQ-G is a 16-channel, low-charge injection, high-voltage analog switch 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/VNN combinations such as +40V/-160V, +100V/-100V, and +160V/-40V. It features a 3.3V input logic level compatible serial data shift register with latches for efficient control. Key electrical parameters include a maximum ON-resistance of 38 Ohms at VPP=+40V and VNN=-160V, a small signal frequency response up to 50 MHz, and a typical OFF-isolation of -60 dB at 5.0 MHz.

Analog Switches - Special Purpose Feature Summary

• Low parasitic capacitance and very low quiescent power dissipation for enhanced performance.
• Excellent noise immunity and low charge injection characteristics suitable for precision applications.

Analog Switches - Special Purpose Applications

• Medical Ultrasound Imaging
• NDT Metal Flaw Detection
• Piezoelectric Transducer Drivers
• Optical MEMS Modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific package type and marking information against the official datasheet before procurement. Ensure that the ordering suffix corresponds to the required tape and reel or tray packaging configuration. Confirm RoHS compliance status and check for any recent product change notices (PCN) regarding manufacturing site or material changes. Validate that the component meets the required operating temperature range for the intended application environment.

Analog Switches - Special Purpose Selection Notes

Select the HV2601TQ-G when high-voltage switching is required without integrated bleed resistors, distinguishing it from the HV2701 variant. Consider the 48-lead TQFP package for surface mount assembly, noting that the LQFP package is not recommended for new designs. Evaluate the supply voltage requirements to ensure compatibility with the specified VPP and VNN ranges. Assess the need for low charge injection and high OFF-isolation for sensitive signal paths.

Analog Switches - Special Purpose Part Context

The HV2601TQ-G belongs to the HV2601/HV2701 family of low-charge injection, 16-channel, high-voltage analog switches. This series is designed for applications requiring high-voltage switching controlled by low-voltage logic signals. The TQFP package designation indicates a 48-lead Plastic Thin Quad Flatpack. The family shares core functionality but differs in features such as the presence of integrated bleed resistors in the HV2701 model.

Analog Switches - Special Purpose Replacement Considerations

The HV2701TQ-G is a functional substitute within the same family, differing primarily by the inclusion of integrated bleed resistors on the outputs. Verify if the bleed resistor feature is acceptable or detrimental to the specific circuit design. Other variants in the HV2601 series may offer different package options, such as the LQFP, though the datasheet advises against using LQFP for new designs.
