HV2070/AJA

Analog Switches - Special Purpose Overview

The HV2070/AJA is a 32-channel high-voltage analog switch utilizing L-Switch architecture, eliminating the need for high-voltage bias supplies. It operates with ±6V or ±5V logic and power rails while transmitting ±100V analog signals. The device features a typical on-resistance of 4.5 Ω and supports both individual switching (MODE=H) and bank switching (MODE=L) modes via a serial interface. Key electrical parameters include a 66 MHz data shift clock frequency, 100 MHz small-signal bandwidth, and peak output current up to 3.7 A. It is housed in a 10x10 mm TFBGA package.

Analog Switches - Special Purpose Feature Summary

• L-Switch architecture reduces on-resistance and parasitic capacitance for high-power applications
• Dual-mode operation allows independent channel control or 16PDT bank switching
• Low harmonic distortion and low charge injection characteristics
• Integrated standby mode significantly reduces quiescent current consumption

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Non-destructive testing metal flaw detection
• Piezoelectric transducer drivers
• Inkjet printer heads
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'AJA' against official Microchip documentation to confirm package marking or tape-and-reel specifications. Ensure supply voltages adhere to the recommended operating conditions: VDD between +4.5V and +6.3V, VSS between -6.3V and -4.5V, and VLL between 3.0V and 3.6V. Confirm that the application environment remains within the specified 0°C to +70°C operating temperature range.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage signal routing controlled by low-voltage logic without external high-voltage bias generation. The device is suitable for shear wave elastography and HIFU applications due to its low on-resistance and high power dissipation capability. Consider the daisy-chainable serial interface if multiple units are required to expand channel count in complex array systems.

Analog Switches - Special Purpose Part Context

This device belongs to the HV2XXX series of high-voltage analog switches from Microchip Technology. It is specifically engineered for medical and industrial applications demanding reliable high-voltage switching with minimal signal distortion. The L-Switch technology differentiates it from standard CMOS switches by enabling direct handling of ±100V pulses.
