LTC2415-1CGN#PBF - 24-Bit Analog-to-Digital Converter

The LTC2415-1CGN#PBF is a high-precision 24-bit Analog-to-Digital Converter (ADC) from Linear Technology, designed for direct digitization of low-frequency, high-impedance sensor outputs. This ADC features a unique No Latency ΔΣ™ architecture which provides a true differential input and differential reference without sacrificing speed or accuracy.

With an impressive 2ppm INL and 0.6ppm RMS noise, the LTC2415-1CGN#PBF is capable of delivering outstanding performance that is critical for high-end instrumentation, industrial control systems, and medical equipment. It operates from a single 2.7V to 5.5V supply, making it suitable for both battery-powered and line-powered applications.

The device comes in a compact 16-lead narrow SSOP package, with the part number suffix "CGN" indicating the package type and "#PBF" denoting the lead-free, RoHS-compliant version. Its small footprint and low power consumption, typically 1.4mA, are ideal for space-constrained and power-sensitive applications.

Key features of the LTC2415-1CGN#PBF include:

• True differential inputs with a common mode range from ground to Vcc
• Easy drive design, thanks to its rail-to-rail input buffer
• Flexible input configuration allowing single-ended or differential inputs
• Automatic calibration at every conversion, ensuring accuracy over time and temperature
• Rejection of 50Hz/60Hz line frequency noise, beneficial for industrial environments
• Simple SPI-compatible 3-wire serial interface
• No pipeline delay, providing instantaneous data output and enabling easy multiplexing

The LTC2415-1CGN#PBF is also equipped with an internal oscillator, eliminating the need for external components and simplifying the design process. Its digital filter stabilizes the output data, even with dynamically changing input signals, making it a robust choice for demanding applications.

Whether you're designing precision measurement equipment or integrating high-accuracy data acquisition into a system, the LTC2415-1CGN#PBF from Linear Technology offers a blend of performance, ease of use, and reliability that is hard to match.
