The AD8065/AD80661 FastFET™ amplifiers are voltage feedback amplifiers with FET inputs offering high performance and ease of use. The AD8065 is a single amplifier, and the AD8066 is a dual amplifier. These amplifiers are developed in the Analog Devices, Inc. proprietary XFCB process and allow exceptionally low noise operation (7.0 nV/√Hz and 0.6 fA/√Hz) as well as very high input impedance.

With a wide supply voltage range from 5 V to 24 V, the ability to operate on single supplies, and a bandwidth of 145 MHz, the AD8065/AD8066 are designed to work in a variety of applications. For added versatility, the amplifiers also contain rail-to-rail outputs.

Despite the low cost, the amplifiers provide excellent overall performance. The differential gain and phase errors of 0.02% and 0.02°, respectively, along with 0.1 dB flatness out to 7 MHz, make these amplifiers ideal for video applications. Additionally, they offer a high slew rate of 180 V/µs, excellent distortion (SFDR of −88 dBc @ 1 MHz), extremely high common-mode rejection of −100 dB, and a low input offset voltage of 1.5 mV maximum under warmed up conditions. The AD8065/AD8066 operate using only a 6.4 mA/amplifier typical supply current and are capable of delivering up to 30 mA of load current.

The AD8065/AD8066 are high performance, high speed, FET input amplifiers available in small packages: SOIC-8, MSOP-8, and SOT-23-5. They are rated to work over the industrial temperature range of −40°C to +85°C.

The AD8065WARTZ-R7 is fully qualified for automotive applications. It is rated to operate over the extended temperature range (−40°C to +105°C), up to a maximum supply voltage range of ±5 V only

AD-PAARRAY3552R-SL

RF Front-end GaN Power Amplifier Biasing, Protection, and Control Reference Design

RF Front-end GaN Power Amplifier Biasing, Protection, and Control Reference Design

Features and Benefits

  • Designed to cover full Tx signal chains with integrated MCU and user-friendly GUI for faster and easier integration
  • Supports fault event protection - overvoltage (OV), overcurrent (OC), and overtemperature (OT)
  • Supports ultrafast sub-µs GaN gate voltage switching ~ (<1 µs)
  • Supports ultrafast (<10 µs) fault event protection from detection up to GaN gate pinch-off
  • Wide range of gate bias voltages from -10 V to +10 V
  • Configurable power-up and power-down sequence

Product Detail

The AD-PAARRAY3552R-SL reference design provides control, protection, and proper biasing sequence for GaN power amplifier (PA) arrays. The design incorporates the AD3553R high-speed, dual-channel, 16-bit DAC to support the ultrafast sub-µs voltage settling time of GaN gates.

Key fault events, including overvoltage, overcurrent, and overtemperature, are effectively managed by the LTC7000, a static switch driver responsible for system fault protection.

The on-board MAX32666 ultralow-power ARM® Cortex®-M4 microprocessor provides essential debug and programming features for a comprehensive software development experience with the system. The system's firmware is built on ADI's open-source no-OS framework and includes a user-friendly graphical interface (GUI) for evaluation. Updates are easily applied through an SWD UART bootloader, streamlining prototyping.

The system can be powered by an external +48 V supply, requiring high current capabilities.
