Overview
The LTC1290DISW#PBF is a single-chip 12-bit data acquisition system produced by Analog Devices Inc. This component integrates a serial I/O successive approximation analog-to-digital converter (ADC) and an 8-channel input multiplexer. It utilizes LTCMOS™ switched capacitor technology, enabling it to perform either 12-bit unipolar or 11-bit plus sign bipolar A/D conversions. The device is designed for applications requiring low power consumption and can be powered down with a serial word when idle.
