Overview
The LTC1290DIN#PBF, produced by Analog Devices Inc., is a single-chip 12-bit data acquisition system. This integrated circuit incorporates a serial I/O successive approximation analog-to-digital converter (ADC) and utilizes LTCMOS™ switched capacitor technology. The device is capable of performing either 12-bit unipolar or 11-bit plus sign bipolar A/D conversions. It features an 8-channel input multiplexer that can be configured for either 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 conversion process. The LTC1290DIN#PBF is particularly useful in applications where low power consumption is a critical requirement, as it can be powered down with a serial word when idle.
