LTC2448IUHF - High Precision, 24-Bit, No Latency Delta-Sigma ADC

The LTC2448IUHF from Linear Technology is a high-precision, 24-bit, no latency delta-sigma Analog-to-Digital Converter (ADC) that offers a unique combination of flexibility and performance. Designed for applications requiring high dynamic range, accuracy, and no latency in measurement, this ADC is an ideal choice for industrial, medical, and automotive systems, as well as instrumentation and control applications.

One of the standout features of the LTC2448IUHF is its wide input range. The device can accept differential input ranges up to ±Vref, with Vref ranging from 2.5V to 5.1V, which allows for a broad spectrum of sensor types and signal amplitudes to be accurately digitized. This adaptability makes the LTC2448IUHF versatile for various use cases without the need for additional signal conditioning hardware.

The LTC2448IUHF also boasts an impressive oversampling ratio (OSR) that can be set from 64 to 4096, which enables the user to optimize the trade-off between resolution and conversion speed. With its no latency feature, the ADC provides a digital output immediately after the first conversion cycle following a change in the input signal or configuration settings, ensuring real-time data acquisition and control.

The device operates over a -40°C to 85°C temperature range and comes in a compact 38-lead QFN package, making it suitable for space-constrained applications. Its SPI-compatible serial interface allows for easy integration with microcontrollers and digital systems.

Additional features include multiple programmable gain options, a 2ppm INL (Integral Nonlinearity), and a 5ppm offset. The LTC2448IUHF also includes a built-in oscillator, eliminating the need for external components and simplifying the design process.

With its exceptional performance and versatility, the LTC2448IUHF from Linear Technology stands out as a top-tier ADC solution for engineers looking to enhance the precision and efficiency of their data acquisition systems.
