HV2801K6-G

Analog Switches - Special Purpose Overview

The HV2801K6-G is a 32-channel low-charge-injection high-voltage analog switch integrated circuit manufactured by Microchip Technology. It operates with flexible supply voltages, supporting VPP/VNN combinations such as +40V/-160V, +100V/-100V, and +160V/-40V. The device features a maximum on-resistance of 48 ohms at VPP=+40V and VNN=-160V, with a typical value of 26 ohms. It supports a DC to 50 MHz analog signal frequency and includes a cascadable serial data register with latches for control. The logic interface accepts 3.3V or 5V CMOS input levels, drawing a quiescent current of 10 µA. The component is housed in a 64-lead QFN package.

• 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 aligns with project requirements. Ensure the datasheet revision matches the design specifications. Validate that the thermal pad connection to VNN is implemented correctly during assembly.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage switching with minimal signal degradation. The HV2801 variant is appropriate for applications not requiring integrated bleed resistors. Verify that the operating voltage range meets the system's peak-to-peak signal requirements. Consider the serial interface timing constraints when integrating with the host controller.

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 HV2801 serves as the base model without integrated bleed resistors, while the HV2901 includes them for capacitive load discharge. Both share identical pinouts and electrical characteristics except for the bleed resistor feature.

Analog Switches - Special Purpose Replacement Considerations

The HV2901K6-G is a direct functional substitute within the same family, differing only by the inclusion of integrated output bleed resistors. Designers must verify if the additional bleed resistance impacts the specific application requirements before swapping parts.
