DC2222A-B

DC2222A-B demonstration circuit features the LTC2508-32 ADC. The LTC2508-32 is low power, low noise, high speed, 32bit SAR ADC with an integrated configurable digital averaging filter that operate from a single 2.5V supply. The DC2222A-B demonstrates the DC and AC performance of the LTC2508-32 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 –9V GND 9V 0V TO VREF 0V TO VREF 100MHz MAX 2.5VP-P 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 DC2222A is intended to show recommended grounding, component placement and selection, routing and bypassing for this ADC.
