HV2201FG-G-M931

Analog Switches - Special Purpose Overview

The HV2201FG-G-M931 is an 8-channel high voltage analog switch IC manufactured by Microchip Technology, utilizing HVCMOS technology. It operates with a logic supply (VDD) of 3.0V to 5.5V and supports flexible high voltage supplies (VPP/VNN) ranging from +40V/-160V to +160V/-40V. The device features a serial data shift register with latches for control, supporting clock frequencies up to 20MHz at VDD=5.0V. It provides DC to 50MHz analog signal bandwidth, low charge injection (typically 350pC), and excellent noise immunity. Packaged in a 48-LQFP (7x7mm) format, it is designed for applications requiring efficient control of high voltage analog signals.

Analog Switches - Special Purpose FAQ

How does the latch enable (LE) signal affect data input?

Data is clocked into the shift register on the rising edge of the clock. The switches retain their previous state until the LE signal goes high, at which point the shift register data flows through to the latches and updates the switch states.

What is the maximum clock frequency supported?

The device supports a data shift clock frequency of up to 20MHz when the logic supply voltage (VDD) is 5.0V. At 3.0V, the maximum frequency is 8MHz.

What is the typical off-isolation performance?

The device offers -60dB typical off-isolation at 5.0MHz with a 50Ω load. With a 1.0kΩ/15pF load, the off-isolation is typically -30dB at 5.0MHz.
