ADC14C105CISQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC14C105CISQ/NOPB is a single-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 105 MS/s and features a 1.0 GHz input bandwidth. The device utilizes a pipeline architecture and accepts differential analog inputs via a parallel digital interface. Power requirements include 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 73 dB, an effective number of bits (ENOB) of 11.4 bits, and a total power consumption of 400 mW. Nonlinearity specifications are defined by a differential nonlinearity (DNL) of +/- 0.5 LSB and an integral nonlinearity (INL) of 1.5 LSB. The component is housed in a WQFN-32 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity levels and recommended reflow profiles prior to assembly. Ensure compatibility with required clocking and reference voltage sources specified in the electrical characteristics section.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution conversion is required at moderate sampling speeds. Compare against dual-channel variants if simultaneous multi-input acquisition is necessary. Evaluate power budgets against the 400 mW typical consumption. Consider the WQFN-32 footprint constraints during PCB layout planning. Verify that the parallel interface aligns with the target FPGA or ASIC capabilities.
