Overview
The ADS8411IBPFBT is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS8411 series and is characterized by its high-speed, high-resolution, and low-power consumption. The ADS8411IBPFBT features a successive approximation register (SAR) architecture with an inherent sample and hold function, making it suitable for a wide range of applications requiring precise and rapid data acquisition.
The device operates at a sample rate of 2 MHz and includes an internal 4.096-V reference, which can also be used with an external reference if needed. It is available in a 48-lead TQFP package and is specified over the industrial temperature range of -40°C to 85°C.
