The LTC1292DCN8#PBF is a 12 bit CMOS, Serial I/O, 8-Channel Multiplexer, designed for the acquisition and control of signals from different transducers. The device operates from supply voltages from single 5V power supply. Each of the eight channels offers a low-power, low-noise, low-distortion input stage that is optimized for best performance. The differential input stage provides a wide dynamic range of up to ±10V. Each channel can be switched independently of the others, allowing for multiple input configurations.

The core of the LTC1292DCN8#PBF consists of a high-speed, low-power CMOS multiplexer. The multiplexer consists of two identical channels that are cascaded, providing simultaneous switching of all channels. Each channel has its own full-scale level and bi-directional gain block. The multiplexer also features an auto-zero/auto-balance logic eliminates offset errors and reduces power consumption. In addition, the multiplexer provides an internal reference level which is adjustable for levels ranging from ±4V to ±10V.

The LTC1292DCN8#PBF also features on-chip digital calibration circuitry that allows programmable current and voltage gains in order to improve the overall accuracy of the device. The calibrated gains can then be programmed and stored in an internal memory for future use. The device also contains a variety of software-selectable options such as differential/single-ended input, input range and data rate selection, for ease of use.

The LTC1292DCN8#PBF is a highly integrated, low cost serial input/output device that makes it suitable for applications such as data acquisition, control systems, sensor and transducer interfacing, industrial automation, and medical instrumentation. It can also be used in mobile or consumer electronic applications. Due to its low power requirements and high integration, the device is able to deliver low cost and reliable performance in a wide range of applications.

In summary, the LTC1292DCN8#PBF is a low power, low cost, high accuracy, 8-channel serial I/O multiplexer. The device features a low-noise, low-distortion, differential input stage for a wide dynamic range of up to ±10V. It also incorporates a digital calibration logic that allows for adjustable current and voltage gains, as well as software-selectable options for the input range and data rate selection. The device is suitable for a wide range of applications including data acquisition, control systems, sensor and transducer interfacing, industrial automation, and medical instrumentation.
