Technical Specifications
The ADC14155CISQ boasts a 14-bit resolution and samples at a rate of 155 million samples per second (MSPS). It features exceptional Signal-to-Noise Ratio (SNR) and Spurious-Free Dynamic Range (SFDR) performance. It utilizes an internal sample-and-hold amplifier to accurately capture input signals. The differential input configuration enhances noise immunity. The digital output is serialized using LVDS, allowing for high-speed data transmission with reduced power consumption. The ADC offers various power-down modes to minimize power consumption when not actively converting signals. The analog input range is typically 1Vpp differential. The device requires both analog and digital supply voltages. It comes in a QFP package.
