  • Breakthrough 0.5ppm INL, 1Msps, No Latency SAR ADC Achieves True 20-Bit Precision

    MILPITAS, CA – May 28, 2013 – Linear Technology Corporation introduces the LTC2378-20 , a 20-bit 1Msps no latency successive approximation register (SAR) analog-to-digital converter (ADC) with exceptionally low 0.5ppm (typ) and 2ppm (max) Integral Non-Linearity (INL) error. INL is a key specification in precision applications, such as seismic monitoring and semiconductor fabrication, indicating how much the ADC transfer function deviates from its ideal. Since linearity effectively cannot be calibrated at the system level, the ADC’s INL specification often sets the overall system accuracy. The best-in-class 0.5ppm INL of the LTC2378-20 enables a new generation of precision systems with true 20-bit accuracy. Proprietary architecture leads to an extremely stable 2ppm (max) INL and -114dB THD (max) over the device’s entire operating range of -40°C to 85°C.
