12-/16-BIT 175ksps ADC LTC1863L/LTC1867L Micropower, 3V, 12-/16-Bit, 8-Channel 175ksps ADCs FEATURES DESCRIPTION n Sample Rate: 175ksps The LTC 1863L/LTC1867L are pin compatible, 8-channel n 16-Bit No Missing Codes and 3LSB Max INL 12-/16-bit A/D converters with serial I/O and an internal n 8-Channel Multiplexer with: reference. n Single Ended or Differential Inputs and The 8-channel input multiplexer can be configured for n Unipolar or Bipolar Conversion Modes either single-ended or differential inputs and unipolar or n SPI/MICROWIRE Serial I/O bipolar conversions (or combinations thereof). The ADCs n 2.7V Guaranteed Supply Voltage convert 0V to 2.5V unipolar inputs or 1.25V bipolar n Pin Compatible with LTC1863/LTC1867 inputs. The ADCs typically draw only 750A from a single n True Differential Inputs 2.7V supply. The automatic nap and sleep modes benefit n On-Chip or External Reference power sensitive applications. n Low Power: 750A at 175ksps, 300A at 50ksps n The LTC1867Ls DC performance is outstanding with a Sleep Mode n 3LSB INL specification and 16-bit no missing codes over Automatic Nap Mode Between Conversions n temperature. 16-Pin Narrow SSOP Package n AEC-Q100 Qualified for Automotive Application Housed in a compact, narrow 16-pin SSOP package, the LTC1863L/LTC1867L can be used in space-sensitive as APPLICATIONS well as low power applications. n All registered trademarks and trademarks are the property of their respective owners.
