Fast 16-bit 5Msps Dual SAR ADC Offers
Flexible Differential Inputs with Wide Common Mode Range
MILPITAS, CA – February 24, 2014 – Linear Technology Corporation introduces the
LTC2323-16, a dual 16-bit 5Msps simultaneous sampling, successive approximation register
(SAR) ADC with flexible differential inputs. The LTC2323-16 supports a wide input common
mode range and simplifies system-level design by relaxing the signal conditioning requirements
to drive the ADC with a wide range of analog signals up to Nyquist frequencies.
The LTC2323-16 leads a family of 16-, 14- and 12-bit SAR ADCs, featuring sample rates
of 5Msps and 2Msps while achieving 81dB SNR at 16 bits, 80dB SNR at 14 bits and 73dB SNR
at 12 bits. The 14- and 12-bit versions feature sign plus magnitude transfer functions, making
them ideally suited for control loop applications. The LTC2323 family integrates a precision
bandgap reference with low drift and guaranteed 20ppm/ºC maximum temperature coefficient
into a small 20mm2 QFN-28 package. The devices can be powered from a 3.3V or 5V supply and
consume just 55mW with a 3.3V supply and 80mW with a 5V supply. The high speed SPIcompatible CMOS or LVDS serial interface is ideal for highly integrated high speed systems.
The LTC2323-16 is available today in commercial, industrial and automotive (-40oC to
125oC) temperature grades. Pricing begins at $13.95 each in 1,000-piece quantities. The
DC1996A evaluation board for the LTC2323 SAR ADC family is available at
www.linear.com/demo or via a local Linear Technology sales office. For more information, visit
