16-Pin Narrow SSOP Package
The LT C
®
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 configured for
either single-ended or differential inputs and unipolar
or bipolar conversions (or combinations 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 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.
