Kit Overview

The LTC2370LTC2370/LTC2369LTC2369/LTC2368LTC2368/LTC2367LTC2367/LTC2364LTC2364 are low power, low noise ADCs with serial outputs that can operate from a single 2.5V supply. The following text refers to the LTC2369-18LTC2369-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2369-18 supports a 0V to 5V pseudo-differential input range with a 96dB SNR, consumes only 18mW and achieves ±2LSB INL max with no missing codes at 18-bits.

The DC1813ADC1813A demonstrates the DC and AC performance of the LTC2369-18LTC2369-18 in conjunction with the DC590 QuikEval and DC718 QuikEval II data collection boards. Use the DC590 to demonstrate DC performance such as peak-to-peak noise and DC linearity. Use the DC718 if precise sampling rates are required or to demonstrate AC performance such as SNR, THD, SINAD and SFDR. The DC1813A is intended to demonstrate recommended grounding, component placement and selection, routing and bypassing for this ADC. Several suggested driver circuits for the analog inputs will be presented.
