ADC14C105CISQ

Analog To Digital Converters (ADC) Overview

The ADC14C105CISQ is a single-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipeline architecture and supports sampling rates up to 105 MSPS with an input bandwidth of 1.0 GHz. The device accepts differential inputs and provides parallel CMOS digital outputs. It operates on a 2.7 V to 3.6 V analog supply and a 2.4 V to 3.6 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB, an effective number of bits (ENOB) of 11.4 bits, and a power consumption of 400 mW. The component is housed in a WQFN-32 package and functions within a temperature range of -40°C to +85°C.
