Overview
The LTC1290CIN#PBF, produced by Analog Devices Inc., is a single-chip 12-bit data acquisition system. This component integrates a serial I/O successive approximation analog-to-digital converter (ADC) and utilizes LTCMOS™ switched capacitor technology. It is capable of performing either 12-bit unipolar or 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 LTC1290CIN#PBF is designed to offer low power consumption, with the ability to power down the device using a serial word when it is idle.
