SPI Interface
The LTC®2383-16 is a 1Msps, no latency SAR ADC that offers low 13mW power consumption, 92dB SNR using a fully differential input range, ±2LSB INL (max) and 16-bit no missing codes resolution. The pinand software-compatible family includes LTC2382-16 (500ksps) and LTC2381-16 (250ksps) and features a proprietary sampling architecture that allows the use of extremely low power ADC drivers, thus reducing the overall power consumption of the entire data acquisition solution. To achieve uncompromised AC performance, we recommend the fast settling LT®6350 ADC driver for single-ended to differential conversion of input signals. We also recommend the LTC6652-2.5, a precision external reference with high accuracy, low power and small size. The –40°C to 125°C temperature range of LT6350 and LTC6652 complements that of LTC2383 family and makes them ideal for automotive applications.
