The AD797 is a very low noise, low distortion operational amplifier ideal for use as a preamplifier. The low noise of 0.9 nV(root)Hz and low total harmonic distortion of -120 dB at audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles.
Furthermore, the AD797's excellent slew rate of 20 V/µs and 110 MHz gain bandwidth make it highly suitable for low frequency ultrasound applications.
The AD797 is also useful in IR and Sonar Imaging applications where the widest dynamic range is necessary. The low distortion and 16-bit settling time of the AD797 make it ideal for buffering the inputs to Sigma Delta ADCs or the outputs of high resolution DACs especially when they are used in critical applications such as seismic detection and spectrum analyzers. Key features such as a 50 mA output current drive and the specified power supply voltage range of ±5 to ±15 volts make the AD797 an excellent general purpose amplifier.

The ADSP-SC589 EZ-KIT Lite and EZ-Board® are evaluation systems for the ADSP-SC58x family of SHARC® processors. The ADSP-SC589 processor is based on the SHARC+™ core dual processor with the ARM® Cortex-A5™ processor core and is designed for a wide array of markets, from automotive and pro-audio to industrial-based applications that require high floating-point performance. The EZ-Board is shipped with all of the necessary hardware—you can start the evaluation immediately. The package contains the standalone evaluation board, CE-approved power supply, and USB cable. The EZ-KIT Lite® version ships with two 180 day licenses for CrossCore® Embedded Studio (CCES) and the ICE-1000 emulator, while the EZ-Board version requires the customer to provide an ICE-1000 or ICE-2000 emulator.
Expansion Interface III connectors are provided for interfacing with additional extender boards to provide LCD, camera, video, and audio. Traditional mechanical switches for changing the board's factory setup have been removed in favor of I2C controlled software switches. The only remaining mechanical switches are the boot mode switch, JTAG configuration switches, and push buttons.
The evaluation board is designed to be used in conjunction with the -CrossCore® Embedded Studio (CCES) development tools to test capabilities of the ADSP-SC58x processors. The development environment aids advanced application code development and debug, such as:
- Create, compile, assemble, and link application programs written in C++, C, and assembly
- Load, run, step, halt, and set breakpoints in application programs
- Read and write data and program memory
- Read and write core and peripheral registers
