Demonstration circuit DC782A-A features LTC2249 14-Bit, 80Msps Low Power 3V ADC. The circuitry on the analog inputs is optimized for analog input frequencies below 70 MHz.
The LTC2249 is a 14-bit 80Msps, low power 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2249 is perfect for demanding imaging and communications applications with AC performance that includes 73dB SNR and 90dB SFDR for signals well beyond 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
