LTC1290
Single Chip 12-Bit Data
Acquisition System U FEATURES DESCRIPTIO ■ The LTC®1290 is a data acquisition component which
contains a serial I/O successive approximation A/D converter. It uses LTCMOSTM switched capacitor technology
to perform either 12-bit unipolar or 11-bit plus sign bipolar
A/D conversions. The 8-channel input multiplexer can be
configured for either single-ended or differential inputs (or
combinations thereof). An on-chip sample-and-hold is
included for all single-ended input channels. When the
LTC1290 is idle it can be powered down with a serial word
in applications where low power consumption is desired. ■
