LTC2489IDE#TRPBF - 16-Bit ΔΣ ADC with Easy Drive Input Current Cancellation

The LTC2489IDE#TRPBF is a highly sophisticated 16-bit analog-to-digital converter (ADC) from Linear Technology, designed to offer exceptional accuracy and ease of use in a wide array of applications. Its standout feature is the Easy Drive technology, which significantly reduces the input current, thereby simplifying the design of input driving circuits and ensuring a high-impedance input that is easy to drive.

This ADC operates using a delta-sigma (ΔΣ) conversion technique which provides a 16-bit output with no missing codes. The LTC2489IDE#TRPBF has an integrated oscillator, eliminating the need for external components to set the conversion rate, and a 2-wire I2C-compatible serial interface, which makes it easy to communicate with microcontrollers and other digital systems.

The LTC2489IDE#TRPBF is capable of direct digitization of a wide variety of signals with its differential input range of ±VREF, where VREF can be between 2.5V and 5.1V. This flexibility allows the ADC to be used in systems requiring precise measurement of signals from thermocouples, RTDs, and pressure sensors, among others.

One of the key features of this device is its temperature sensor that provides an internal temperature measurement, enabling temperature compensation or monitoring without the need for additional sensors. It also offers a configurable digital filter, which can be set to optimize the balance between the conversion rate and 50Hz/60Hz rejection, according to the specific requirements of the application.

The LTC2489IDE#TRPBF is available in a compact 14-lead DFN package, making it suitable for space-constrained applications. Its specified temperature range from -40°C to 85°C ensures reliable operation in diverse environments. With its combination of high precision, ease of use, and versatility, the LTC2489IDE#TRPBF is an ideal choice for high-resolution data acquisition systems, industrial control systems, and instrumentation.

Whether you are designing a sophisticated industrial process control system or a sensitive data acquisition platform, the LTC2489IDE#TRPBF offers the performance and features needed to meet the demands of your application.
