Texas Instruments ADC32RF45
The ADC32RF45 device is a 14-bit, 3.0-GSPS, dualchannel, analog-to-digital converter (ADC) that supports RF sampling with input frequencies up to 4 GHz and beyond. Designed for high signal-to-noise ratio (SNR), the ADC32RF45 delivers a noise spectral density of –155 dBFS/Hz as well as dynamic range and channel isolation over a large input frequency range. The buffered analog input with onchip termination provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy.| Part No. | ADC32RF45 |
