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.

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.
