The ADCs typically draw only 1.3m A from a single 5V supply. The 8-channel input multiplexer can be configured for either single-ended or differential inputs and unipolar or bipolar conversions (or binations thereof). The automatic nap and sleep modes benefit power sensitive applications. The LTC1867’s DC performance is outstanding with a ±2LSB INL specification and no missing codes over temperature. The signal-to-noise ratio (SNR) for the LTC1867 is typically 89d B, with the internal reference. Housed in a pact, narrow 16-pin SSOP package, the LTC1863/LTC1867 can be used in space-sensitive as well as low-power applications. , LTC and LT are registered trademarks of Linear Technology Corporation.
