High Voltage Interface

High Voltage Sample and Hold Amplifier Array

Part Number: HV257DB2

No Longer Available
The HV257DB2 is a 32-Channel, 295V, sample and hold amplifier array with a nominal gain of 72V/V. The purpose of the HV257DB2 is to provide a means to easily evaluate the HV257FG-G device. A high voltage supply, VPP, and four low voltage supplies, AVDD and DVDD, AVNN and DVNN, are required. Referring to the demo board drawing shown below, the logic and VSIG connections are on the left, the high voltage outputs are on the bottom, and the supplies are on the right.

The HV582 96-Channel High-Voltage Driver IC Evaluation Board facilitates the quick implementation for display and printer driver applications with its flexible input/output connection interface. The Evaluation Board is designed around the HV582, a unipolar, 96-channel low-voltage serial to high-voltage parallel converter with push-pull outputs. This device has been designed for applications requiring multiple high-voltage outputs with current sinking and sourcing capabilities. The device consists of six parallel 16-bit shift registers, a 96-bit latch and 96 high-voltage outputs. Data can be input at 30 MHz.
The HV583 128-Channel High-Voltage Driver IC Evaluation Board facilitates the quick implementation for display and printer driver applications with its flexible input/output connection interface. The Evaluation Board is designed around the HV583, a unipolar, 128-channel low-voltage serial to high-voltage parallel converter with push-pull outputs. This device has been designed for applications requiring multiple high-voltage outputs with current sinking and sourcing capabilities. The device consists of four parallel 32-bit shift registers, a 128-bit latch and 128 high-voltage outputs. Data can be input at 40 MHz.
The HV9150DB1 demoboard is for the evaluation of the HV9150 hysteretic DC/DC controller. This demoboard consists of all necessary components to create a 5V to 200V step up converter capable of providing 600mW of output power. This DC/DC converter has a single voltage input and a single voltage output. The demoboard is configured to use the internal voltage reference. In addition, the user also has access to an external voltage reference pin if it is preferred. The output voltage can be adjusted from 50V to 200V by adjusting the potentiometer next to the output terminals. The potentiometer is used in the resistor feedback network for demonstration purposes. The demoboard shows that all necessary components for this 600mW converter can be packed into a square inch, single sided, PCB area. To ensure a stable operation of the DC/DC converter, it is recommended that a low ESR bulk decoupling capacitor be connect at the input voltage supply.
The Laser Tracking and MEMS Mirror Demonstrator Kit is a plug-and-play kit with laser beam-steering MEMS mirror device, assembled in a compact opto-mechanical assembly, and control electronics. The kit is designed to demonstrate the capabilities of Microchip's PIC32MZ and HV264 high voltage analog amplifier to drive Mirrorcle’s MEMS mirror with simple Windows-based applications.

The demonstrator kit uses Microchip's fast PIC32MZ MCU and Microchip's HV264 High Voltage amplifier to control a Mirrorcle MEMs mirror. Its main function is to interface with user software, store prepared waveforms in a buffer, and run/output those waveforms in open loop to drive the MEMS mirror and peripherals. The kit is powered and controlled by USB.

The kit can be used to demonstrate the use of MEMS mirror technology in various applications like
  1. Displaying Vector content (eg: Laser marking, 3D printing, HUDs)
  2. Imaging (eg: LIDAR, robot vision, biomedical imaging)
  3. Tracking (eg: AR/VR headset, gaming, laser tracking)
