Available in 20-Lead PDIP and 20-Lead SW Packages The LTC®1289 is a 3V data acquisition component which
contains a serial I/O successive approximation A/D converter. The device specifications are guaranteed at a
supply voltage of 2.7V. It uses LTCMOSTM switched capacitor technology to perform a 12-bit unipolar, or 11-bit
plus sign bipolar A/D conversion. The 8 channel input
multiplexer can be configured for either single-ended or …
