    Ultralow Power 16-Bit High Speed Signal Chain Solution for
    Portable Sampling Systems
    Clarence Mayott The LTC2195 family of ultralow power, dual 16-bit, 25Msps to 125Msps analog-to-digital
    converters (ADCs) dissipate half the power of competing 16-bit solutions, extending
    battery run times in portable electronics. Despite consuming only ~1.5mW/Msps per
    channel, the LTC2195 does not shirk performance to save power, yielding a 76.8dB
    signal-to-noise ratio (SNR) and 90dB of spurious free dynamic range (SFDR) at baseband (0MHz–62.5MHz, the first Nyquist zone). Serial LVDS outputs reduce the number
    of data lines required for routing the ADC data while minimizing digital feedback.
    SIGNAL PATH DESIGN The LTC2195 family is an ideal solution for applications that require 16-bit
    performance and ultralow power consumption to extend battery life. Portable
    medical imaging equipment is a perfect
    example. In many imaging applications
    the signal from the image sensor must
    be conditioned before being sampled by
    the ADC. For this task, it is important to
    choose a low noise, low power amplifier that matches the performance of the
    ADC, such as the LTC6406, which makes
    a good match for the LTC2195 family.
    The LTC6406 is a fully differential
    amplifier with low noise (1.6nV/√Hz at
    the input) and high linearity (+44dBm
    OIP3 at 20MHz) in a small 3mm × 3mm QFN package. External resistors set the
    gain, giving the user maximum design ...
