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 (0MHzвЂ“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/в€љHz at
the input) and high linearity (+44dBm
OIP3 at 20MHz) in a small 3mm Г— 3mm QFN package. External resistors set the
gain, giving the user maximum design …
