Measuring L, C, R
With the industry’s largest portfolio of DDS-based signal sources, transimpedance amplifiers for measurement, and low-resistance switches, ADI offers a complete suite of components suitable for building discrete, high-performance LCR meters for applications ranging from 1 kHz to more than 100 MHz. In addition, ADI offers a family of ARM Cortex™-M3-based, single-chip solutions incorporating high resolution ADCs suitable for a variety of handheld and portable applications
The AD9954 is a direct digital synthesizer (DDS) that uses advanced technology, coupled with an internal high speed, high performance DAC to form a complete, digitally programmable, high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 160 MHz. The AD9954 enables fast frequency hopping coupled with fine tuning of both frequency (0.01 Hz or better) and phase (0.022° granularity).
The AD9954 is programmed via a high speed serial I/O port. The device includes static RAM to support flexible frequency sweep capability in several modes, plus a user-defined linear sweep mode of operation. Also included is an on-chip high speed comparator for applications requiring a square wave output. An on-chip oscillator and PLL circuitry provide users with multiple approaches to generate the device’s system clock.
The AD9954 is specified to operate over the extended industrial temperature range.
