12-/16-BIT 200ksps ADC LTC1863/LTC1867 12-/16-Bit, 8-Channel 200ksps ADCs FEATURES DESCRIPTION n AEC-Q100 Qualified for Automotive Applications The LTC 1863/LTC1867 are pin-compatible, 8-channel n Sample Rate: 200ksps 12-/16-bit A/D converters with serial I/O, and an internal n 16-Bit No Missing Codes and 2LSB Max INL reference. The ADCs typically draw only 1.3mA from a n 8-Channel Multiplexer with: single 5V supply. 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 n SPI/MICROWIRE Serial I/O or bipolar conversions (or combinations thereof). The n Signal-to-Noise Ratio: 89dB automatic nap and sleep modes benefit power sensitive n Single 5V Operation applications. n On-Chip or External Reference n The LTC1867s DC performance is outstanding with a Low Power: 1.3mA at 200ksps, 0.76mA at 100ksps n 2LSB INL specification and no missing codes over tem- Sleep Mode n perature. The signal-to-noise ratio (SNR) for the LTC1867 Automatic Nap Mode Between Conversions n is typically 89dB, with the internal reference. 16-Pin Narrow SSOP Package Housed in a compact, narrow 16-pin SSOP package, the LTC1863/LTC1867 can be used in space-sensitive as well APPLICATIONS as low-power applications. n Industrial Process Control All registered trademarks and trademarks are the property of their respective owners. n High Speed Data Acquisition n Battery Operated Systems n Multiplexed Data Acquisition Systems n Imaging Systems BLOCK DIAGRAM Integral Nonlinearity vs Output Code (LTC1867) 2.0 1.5 1 LTC1863/LTC1867 16 CH0 V DD 2 15 CH1 GND 1.0 3 14 CH2 SDI 4 13 ANALOG CH3 + SERIAL SDO 0.5 5 12 INPUT PORT CH4 SCK 6 11 MUX 0 CH5 CS/CONV 7 10 V CH6 REF 8 INTERNAL 0.5 CH7/COM 2.5V REF 1.0 9 REFCOMP 1.5 18637 BD 2.0 0 16384 32768 49152 65536 OUTPUT CODE 18637 GO1 Rev.
