General part information

LTC1867 Series

The LTC1863L/LTC1867L are pin compatible, 8-channel 12-/16-bit A/D converters with serial I/O and an internal reference.The 8-channel input multiplexer can be configured for either single-ended or differential inputs and unipolar or bipolar conversions (or combinations thereof). The ADCs convert 0V to 2.5V unipolar inputs or ±1.25V bipolar inputs. The ADCs typically draw only 750µA from a single 2.7V supply. The automatic nap and sleep modes benefit power sensitive applications.The LTC1867L's DC performance is outstanding with a ±3LSB INL specification and 16-bit no missing codes over temperature.Housed in a compact, narrow 16-pin SSOP package, the LTC1863L/LTC1867L can be used in space-sensitive as well as low power applications.APPLICATIONSIndustrial Process ControlHigh Speed Data AcquisitionBattery Operated SystemsMultiplexed Data Acquisition SystemsImaging Systems
