Overview
Product Details
The LTC2378-20, LTC2377-20 and LTC2376-20 are 20‑bit, low power, low noise SAR ADCs with serial outputs that operate from a single 2.5V supply. The demo manual refers to the LTC2378-20 but applies to all parts in the family, the only difference being the maximum sample rate. The LTC2378-20 supports a ±5V fully differential input range with a 104dB SNR, consumes only 21mW and achieves ±2ppm INL max with no missing codes at 20 bits. The DC1925A demonstrates the DC and AC performance of the LTC2378-20 in conjunction with the DC590 QuikEval™ and DC890 PScope™ data collection boards. Use the DC590 to demonstrate DC performance such as peak-to-peak noise and DC linearity.
