n 16-Pin Narrow SSOP Package
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 congured 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 benet
power sensitive applications.
The LTC1867L’s DC performance is outstanding with a
±3LSB INL specication 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.
