ADC14DS105CISQE/NOPB

Analog To Digital Converters (ADC) Overview

The ADC14DS105CISQE/NOPB is a single-channel, 14-bit analog-to-digital converter (ADC) from the Texas Instruments ADC14C/DSxxx series. It operates at a sampling rate of 105 MSPS with an input bandwidth up to 1 GHz, supporting intermediate frequency (IF) sampling without down-conversion stages. The device features a pipeline architecture with differential inputs and parallel CMOS digital outputs. It functions within an analog supply voltage range of 2.7 V to 3.6 V and a digital supply range of 2.4 V to 3.6 V. 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 approximately 400 mW.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation, as the part is currently listed under Texas Instruments following industry consolidation. Confirm the specific suffix 'QE' indicates the extended temperature range (-40°C to +85°C) and quad-flat no-lead package variant. Ensure compatibility with the ADC14C105EB/NOPB development kit if evaluation is required.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 14-bit conversion is required with parallel CMOS output compatibility. It serves as a direct upgrade path from 12-bit devices in the same family due to pin compatibility. Consider the 400 mW power dissipation for thermal management in dense circuit designs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC14C/DSxxx series, which includes both single-channel (DS) and dual-channel (C) variants. These parts are designed for high dynamic performance with low noise, allowing designers to simplify signal paths by reducing the need for external filtering amplifiers. The series supports seamless migration between 12-bit and 14-bit resolutions.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC14C105CISQ/NOPB is a closely related single-channel variant in the same series. Verify if the dual-channel version (e.g., ADC14C105) is suitable if additional channels are needed, noting that pinouts may differ between single and dual-channel packages.
