Overview
The LTC1290CCSW#PBF is a single-chip 12-bit data acquisition system produced by Analog Devices Inc. This component integrates a serial I/O successive approximation A/D converter, utilizing LTCMOS™ switched capacitor technology. It supports both 12-bit unipolar and 11-bit plus sign bipolar A/D conversions. The device features an 8-channel input multiplexer that can be configured for single-ended or differential inputs, or a combination of both. An on-chip sample-and-hold circuit is included for all single-ended input channels, enhancing the accuracy of the conversions. The LTC1290 is particularly useful in applications where low power consumption is a priority, as it can be powered down with a serial word when idle.
