ADC14DC105CISQE/NOPB

Analog To Digital Converters (ADC) Overview

The ADC14DC105CISQE/NOPB is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 105 MSPS with an input bandwidth up to 1 GHz, supporting intermediate frequency (IF) sampling without requiring down-conversion stages. The device features a pipeline architecture with differential inputs and parallel CMOS outputs. It functions within an analog supply voltage range of 2.7 V to 3.6 V and a digital supply voltage range of 2.4 V to 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of approximately 73 dB and an effective number of bits (ENOB) of 11.4 bits. The component is housed in a 60-pin WQFN package measuring 9 mm x 9 mm.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC14C/DSxxx family of high-speed pipeline ADCs from Texas Instruments. It is the dual-channel variant of the single-channel ADC14C105. The 'QE' suffix indicates an extended industrial temperature range (-40°C to +85°C), while '/NOPB' denotes a lead-free, halogen-free, and RoHS-compliant packaging configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The single-channel equivalent is the ADC14C105CISQE/NOPB. For lower resolution requirements, the ADC12DC105 series offers pin-compatible 12-bit alternatives.
