The LTC

®

1863/LTC1867 are pin-compatible, 8-channel 

12-/16-bit A/D converters with serial I/O, and an internal 
reference. The ADCs typically draw only 1.3mA from a 
single 5V supply.

The 8-channel input multiplexer can be confi gured for 
either  single-ended  or  differential  inputs  and  unipolar 
or bipolar conversions (or combinations thereof). The 
automatic nap and sleep modes benefi t power sensitive 
applications.

The LTC1867’s DC performance is outstanding with a 
±2LSB INL specifi cation and no missing codes over tem-
perature. The signal-to-noise ratio (SNR) for the LTC1867 
is typically 89dB, with the internal reference.

Housed in a compact, narrow 16-pin SSOP package, the 
LTC1863/LTC1867 can be used in space-sensitive as well 
as low-power applications.
