LTC2486IDE#PBF - 16-Bit ΔΣ ADC with Easy Drive Input Current Cancellation

The LTC2486IDE#PBF is a highly sophisticated 16-bit ΔΣ (Delta-Sigma) analog-to-digital converter (ADC) from Linear Technology, designed to provide precision measurement solutions for a wide range of applications. This integrated circuit offers an exceptional combination of accuracy, ease of use, and versatility, making it an ideal choice for high-resolution data acquisition systems.

One of the standout features of the LTC2486IDE#PBF is its Easy Drive technology, which significantly reduces the input current, allowing direct sensor digitization without the need for external signal conditioning. This technology simplifies the design process and reduces system complexity and cost. The input current cancellation capability minimizes the charge kickback effect, making it easier to drive the ADC inputs, especially beneficial when interfacing with high-impedance sources.

This ADC operates over a wide supply voltage range of 2.7V to 5.5V, making it suitable for both portable battery-powered devices and line-powered equipment. It boasts a high level of integration, featuring an onboard oscillator, temperature sensor, and a configurable digital filter, which enhances the noise immunity and allows for adjustable data rates suitable for various applications.

The LTC2486IDE#PBF offers a pseudo-differential input range of ±VCC, ensuring that both single-ended and differential signals can be accurately measured. This flexibility is critical for applications requiring precise measurement of small signal amplitudes in the presence of large common-mode voltages. The device also includes a No Latency ΔΣ™ feature, which eliminates the delay in the data output that is typically associated with traditional ΔΣ converters.

Communication with the LTC2486IDE#PBF is achieved via a simple 3-wire SPI-compatible serial interface, which allows for easy integration with microcontrollers and digital systems. The compact 12-lead DFN package ensures a minimal footprint on the PCB, providing a space-efficient solution for densely packed electronic designs.

Whether used in industrial instrumentation, medical devices, or precision sensor interfaces, the LTC2486IDE#PBF stands out as a high-performance ADC offering a unique combination of features that enhance both the performance and simplicity of measurement systems.
