LTC2488IDE - 16-Bit, High Precision Delta-Sigma ADC with Easy Drive Input Current Cancellation

The LTC2488IDE is a highly versatile 16-bit analog-to-digital converter (ADC) from Linear Technology, which is now part of Analog Devices. This precision ADC is designed to provide straightforward and reliable data acquisition in a wide range of applications, from industrial control systems to medical devices. Its Easy Drive technology significantly simplifies the design of sensor interfaces by canceling the input current, thus reducing the need for external buffer components.

With its delta-sigma architecture, the LTC2488IDE ensures excellent noise rejection and high-resolution performance, making it suitable for applications that demand accurate signal processing. The ADC operates over a wide supply voltage range of 2.7V to 5.5V, catering to both low-voltage and standard 5V systems. The device also features an internal oscillator, eliminating the need for an external clock source, which simplifies the design and reduces the bill of materials.

The LTC2488IDE offers a flexible input configuration that can be programmed to accept differential inputs or pseudo-differential inputs, allowing for a variety of sensor types to be connected directly to the ADC. It supports an I2C-compatible serial interface, enabling easy communication with microcontrollers and other digital devices.

Key features of the LTC2488IDE include:

• 16-bit resolution with no missing codes
• Easy Drive technology for reduced input current
• Internal oscillator for standalone operation
• Flexible power supply range (2.7V to 5.5V)
• Differential and pseudo-differential input modes
• I2C-compatible serial interface
• Up to 8 differential or 16 single-ended channels
• Automatic cycle-by-cycle calibration for consistent performance

The LTC2488IDE is available in a compact 16-lead DFN package, which is ideal for space-constrained applications. Its industrial temperature range of -40°C to 85°C ensures reliable operation under harsh environmental conditions.

Whether you are designing a precision measurement system or integrating high-quality data acquisition into a product, the LTC2488IDE offers an effective solution that combines performance, ease of use, and versatility.
