HV2901K6-G

Analog Switches - Special Purpose Overview

The HV2901K6-G is a 32-channel high-voltage analog switch IC featuring integrated bleed resistors. It operates with flexible dual supplies ranging from +40V/-160V to +160V/-40V and accepts 3.3V or 5V CMOS logic inputs. The device provides a DC to 50 MHz analog signal frequency, -60 dB typical off-isolation at 5 MHz, and low charge injection of 820 pC at +40V/-160V. It utilizes a cascadable serial data register with latches for control and is housed in a 64-lead QFN package.

Analog Switches - Special Purpose Feature Summary

• Integrated bleed resistors on outputs to eliminate voltage buildup on capacitive loads
• CMOS logic circuitry supporting 3.3V or 5V input levels for low power consumption
• Cascadable serial data register with latches to reduce clock feed-through noise
• High-voltage bilateral DMOS switches combined with low-power CMOS logic

Analog Switches - Special Purpose Applications

• Medical Ultrasound Imaging
• 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 K6 corresponds to the 64-lead QFN package configuration. Confirm environmental compliance status indicated by the G suffix matches project requirements. Ensure supply voltages align with recommended operating conditions before integration.

Analog Switches - Special Purpose Selection Notes

Select this component when high-voltage switching is required alongside low-voltage digital control. The integrated bleed resistors make it suitable for driving piezoelectric transducers where voltage buildup must be prevented. Compare against the HV2801 if bleed resistors are not needed for the specific application load.

Analog Switches - Special Purpose Part Context

This part belongs to the HV2801/HV2901 family of 32-channel low-charge-injection high-voltage analog switches. The primary distinction between the HV2901 and the HV2801 is the inclusion of internal bleed resistors in the HV2901 variant, designed specifically for managing capacitive loads.

Analog Switches - Special Purpose Replacement Considerations

HV2801K6-G: Identical form factor and functionality but lacks integrated bleed resistors.
