The ADS8699IPW is a precision, 18-bit, 500kSPS, analog-to-digital converter (ADC) from Texas Instruments, designed for accuracy and performance in industrial applications. This ADC features a fully-differential input, and a low-drift internal reference which enhances the overall stability and precision of the system.

Key Features

• Resolution: 18-bit resolution provides high precision measurement capabilities, making it suitable for demanding applications that require accurate data conversion.
• Sampling Rate: With a maximum sampling rate of 500kSPS (kilo samples per second), the ADS8699IPW offers a good balance between high-speed and high-resolution data acquisition.
• Input Type: The fully-differential input allows for reduced common-mode noise, leading to improved signal integrity and measurement accuracy.
• Internal Reference: The low-drift (2 ppm/°C), 4.096-V internal reference increases the precision of measurements, ensuring consistent performance over a range of temperatures.
• Interface: It features a SPI-compatible serial interface that supports daisy-chaining of multiple devices, simplifying board design and reducing the number of required digital I/O lines.
• Power Supply: The device operates from a 5-V analog supply and a 1.8-V to 5-V digital supply, making it versatile for interfacing with both analog and digital systems.
