Typical Application

LTC2393-16 Typical Application
LTC2393-16 Typical Application


The LTC2393-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2393-16 supports a large ±4.096V fully differential input range, making it ideal for high performance applications which require maximum dynamic range. The LTC2393-16 achieves ±2LSB INL max, no missing codes at 16-bits and 94.2dB SNR (typ).

The LTC2393-16 includes a precision internal reference with a guaranteed 0.5% initial accuracy and a ±20ppm/°C max) temperature coefficient. Fast 1Msps throughput with no cycle latency in both parallel and serial interface modes makes the LTC2393-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2393-16 dissipates only 140mW at 1Msps, while both nap and sleep power-down modes are provided to further reduce power during inactive periods.

Design Tools


LinearLabTools is a collection of Matlab and Python programs that provide direct access to Linear Technology’s data converter evaluation boards.  An evaluation board for a data converter will typically plug into an accompanying controller board, which is then connected to a host computer running a Linear supplied GUI program such as PScope for Analog-to-Digital converters or LTDACgen for Digital-to-Analog converters. The GUI allows basic performance measurements to be made, but it is not designed to run arbitrary sequences of tests or communicate with other hardware, as is often required by customers when evaluating a part for their own application. LinearLabTools allows customers to control Linear’s data converter demo boards as they would any other piece of test equipment, using their own software.

The LinearLabTools package also contains various application examples, simulations, and educational programs that demonstrate mixed signal concepts.
