    Dual 14-Bit 310Msps ADC
    FEATURES DESCRIPTION 68.8dBFS SNR
    n 88dB SFDR
    n Low Power: 724mW Total
    n Single 1.8V Supply
    n DDR LVDS Outputs
    n Easy-to-Drive 1.32V
    P-P Input Range
    n 1.25GHz Full Power Bandwidth S/H
    n Optional Clock Duty Cycle Stabilizer
    n Low Power Sleep and Nap Modes
    n Serial SPI Port for Configuratio Pin-Compatible 12-Bit Versio 64-Lead (9mm Г— 9mm) QFN Package The LTCВ®2158-14 is a 2-channel simultaneous sampling
    310Msps 14-bit A/D converter designed for digitizing high
    frequency, wide dynamic range signals. It is perfect for
    demanding communications applications with AC performance that includes 68.8dB SNR and 88dB spurious
    free dynamic range (SFDR). The 1.25GHz input bandwidth
    allows the ADC to undersample high frequencies with
    good performance. The latency is only six clock cycles. n DC specs include В±1.2LSB INL (typ), В±0.35LSB DNL (typ)
    and no missing codes over temperature. The transition
    noise is 2.11LSBRMS.
    The digital outputs are double data rate (DDR) LVDS. APPLICATIONS n n n n The ENC+ and ENC– inputs can be driven differentially with
    a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional ...
