LTC2499IUHF#PBF - 24-Bit ADC with Easy Drive Input Current Cancellation by Linear Technology

The LTC2499IUHF#PBF is a high-precision 24-bit Analog-to-Digital Converter (ADC) component, part of Linear Technology's extensive ADC portfolio. This sophisticated device is designed to deliver exceptional accuracy and ease of use for a wide range of applications including industrial measurement, control systems, and data acquisition.

Key to its design is the Easy Drive™ technology, which significantly reduces the input current, allowing direct sensor interfacing without the need for external buffer circuitry. This simplifies the design and reduces the overall power consumption and system cost.

The LTC2499IUHF#PBF offers a versatile selection of inputs and features. It can be configured to measure 16 single-ended channels, 8 differential channels, or any combination thereof. This flexibility makes it suitable for multiplexed applications where multiple sensors need to be read by a single ADC.

With its integrated temperature sensor, the LTC2499IUHF#PBF can provide temperature measurements without the need for additional components, further consolidating system design. The device also features a wide input common-mode range, accepting signals up to the supply rail, which makes it ideal for high-side and low-side sensor measurements.

The ADC operates with a 2-wire I²C-compatible serial interface that supports standard, fast, and high-speed modes, enabling easy integration into existing digital systems. The LTC2499IUHF#PBF also includes a rejection of 50Hz/60Hz noise, which is a common interference in industrial environments, ensuring robust and reliable data conversion even in electrically noisy conditions.

Encased in a compact 20-lead QFN package, the LTC2499IUHF#PBF is designed for space-constrained applications. It operates over an industrial temperature range of -40°C to +85°C, which ensures reliable performance in harsh environments.

Whether you are developing precision instrumentation, data acquisition systems, or any application requiring high-accuracy analog-to-digital conversion, the LTC2499IUHF#PBF from Linear Technology is an excellent choice that combines performance, versatility, and ease of use.
