Demo Board for LTC2251 10-Bit, 125Msps Low Noise 3V ADC
Demonstration circuit DC782A-W features LTC2251 10-Bit, 125Msps Low Noise 3V ADC. The circuitry on the analog inputs is optimized for analog input frequencies between 10 MHz to 170 MHz.
The LTC2251 is a 10-bit 125Msps, low noise 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2251 is perfect for demanding imaging and communications applications with AC performance that includes 61.6dB SNR and 85dB SFDR for signals at the Nyquist frequency.
Note : The DC782 demonstration circuit board should have the following jumper settings: JP1: SHDN: Ground, enables ADC core , JP2: OE: Ground, enables digital outputs , JP3: SENSE: Select VDD for the 2VPP input range SENSE: Select VCM for the 1VPP input range, JP4: MODE: Select VDD (For 2’s complement output format for PScope compatibility) and disables Clock Duty Cycle Stabilizer
Key Applications: Wireless and Wired Broadband Communication, Imaging Systems, Ultrasound, Spectral Analysis, Portable Instrumentation.
