DC2289A-A - LTC2380-24 Demo Board | 24-Bit, 2Msps Fully Differential Input SAR ADC with Integrated Filter (req DC590, DC2026 or DC890)
The LTC®2380-24 and LTC2368-24 are low power, low noise, high speed, 24-bit SAR ADCs with an integrated digital averaging filter that operates from a single 2.5V supply. The following text refers to the LTC2380-24 but applies to both parts, the only difference being that the LTC2380- 24 has fully differential inputs and the LTC2368-24 has pseudo-differential inputs. The LTC2380-24 has –117dB THD, consumes only 28mW and achieves ±4ppm INL max with no missing codes at 24 bits. The DC2289A demonstrates the DC and AC performance of the LTC2380-24 in conjunction with the DC590 or DC2026 QuikEval™ and DC890 PScope™ data collection boards. Use the DC590 or DC2026 to demonstrate DC performance such as peak-to-peak noise and DC linearity. Use the DC890 if precise sampling rates are required or to demonstrate AC performance such as SNR, THD, SINAD and SFDR. The Demonstration Circuit 2289A is intended to show recommended grounding, component placement and selection, routing and bypassing for this ADC.

Software
QuikEval System
The QuikEval system is a USB-based product demonstration and data acquisition system that allows users to quickly evaluate the performance of Linear Technology products. The system consists of a USB Data Acquisition Controller board (DC590B) that connects to individual daughter cards for specific Linear Technology products.
PScope
The PScope System is a USB-based product demonstration and data acquisition system for use with Linear Technology’s high performance ADCs and signal chain receiver family. PScope allows users to evaluate the SNR, SFDR, THD, as well as other key parameters, quickly and easily. Use PScope software with the DC718, DC890 and DC1371 Data Collection Boards.
Linduino
Linduino is an Arduino compatible platform for developing and distributing firmware libraries and code for SPI and I²C-compatible integrated circuits. The Linduino One board interfaces to more than 300 QuikEval demonstration cards, supporting a variety of product types including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power monitors, and more. Firmware libraries for individual devices are written in C and designed to be portable to a wide variety of processors and microcontrollers. Each library has a demonstration program that can be uploaded to the Linduino One platform to allow the circuit and software to be quickly and easily verified.
LinearLabTools
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.
