Beschreibung

This reference design is built keeping an electronic imaging system in mind. Image sensors today force heavy demands on ADCs in terms of: excellent linearity (DNL < 0.5 LSB and INL < 4 LSB), high resolution (12- to 18-bit), high speed (up to 20 MSPS), and high SNR (> 74-dB SNR) to assure superior image quality and freedom from distortion over time. Enabled by the low-noise, high-speed amplifier, fully differential amplifier (FDA), high-speed ADC, and low-noise LDO from TI, this reference design demonstrates how to design a high-performance analog signal chain for digitizing the pixel-output signal in thermal imaging cameras.
