ADC14DS080CISQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC14DS080CISQ/NOPB is a dual-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It operates at sampling rates up to 80 MSPS with a full power bandwidth of 1 GHz. The device utilizes a differential pipeline architecture featuring digital error correction and on-chip sampling hold circuits. It accepts differential analog inputs with a 2 V full-scale differential swing and supports both external and internal 1.2 V voltage references. Digital outputs are provided via serialized differential LVDS signal pairs. The component functions within an industrial temperature range of -40°C to +85°C and consumes approximately 800 mW of power.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor's semiconductor business. Confirm the specific suffix 'CISQ' corresponds to the commercial temperature grade (-40°C to +85°C) and WQFN-60 package configuration. Ensure compatibility with the required 3.0 V or 3.3 V single supply voltage during sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required with high linearity and low noise. The 14-bit resolution and 80 MSPS speed suit applications needing precise digitization of wideband signals. Consider the serialized LVDS output if minimizing pin count and EMI is critical compared to parallel CMOS interfaces available in other family members.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC14C/DSxxx series of advanced dynamic performance analog-to-digital converters. The series offers pin-compatible options ranging from 12-bit to 14-bit resolutions. The ADC14DS080 specifically provides dual-channel capability, distinguishing it from single-channel variants like the ADC14C105, while maintaining similar architectural benefits such as high input bandwidth and low power operation.

Analog To Digital Converters (ADC) Replacement Considerations

Single-channel equivalents include the ADC14C105CISQ/NOPB. For lower speed requirements, the ADC14L040CIVY/NOPB may be considered. Verify that any substitute maintains the WQFN-60 package footprint and LVDS output interface if board layout constraints exist.
