ADC10D1000CIUT

Analog To Digital Converters (ADC) Overview

The ADC10D1000CIUT is a low-power, high-performance CMOS analog-to-digital converter manufactured by Texas Instruments (originally National Semiconductor). It features a dual-channel architecture with 10-bit resolution and a sampling rate of up to 1.0 GSPS per channel, or 2.0 GSPS in single-channel demultiplexed mode. The device utilizes a folding interpolating architecture to achieve a Signal-to-Noise Ratio (SNR) of 57 dB and an Effective Number of Bits (ENOB) of 9.1 bits at 100 MHz input. Key electrical parameters include a differential input type, LVDS parallel output interface, and operation from a single 1.9 V analog supply and 1.8 V to 2 V digital supply. Power dissipation is typically 2.77 W.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 10-bit resolution with 1.0 GSPS sampling rate per channel
• Folding interpolating architecture providing 57 dB SNR and 9.1 ENOB
• LVDS parallel output compatible with IEEE 1596.3-1996 standards
• Integrated programmable gain (15-bit) and offset adjustment (12-bit)

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wideband communication receivers
• Digital oscilloscopes and test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation on the component marking; while originally developed by National Semiconductor, current production and datasheets are managed by Texas Instruments. Confirm the specific suffix 'CIUT' corresponds to the commercial temperature range (-40°C to +85°C) and BGA-292 package. Ensure compliance with RoHS directives if required for the specific revision, as older markings may indicate non-compliant variants.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel digitization at 1 GSPS is required with minimal power consumption. Compare against the ADC10D1500 if higher sampling rates (1.5 GSPS) are needed, noting the trade-off in power dissipation. Ensure the system design supports the 292-ball BGA footprint and provides adequate thermal management for approximately 2.77 W power dissipation.

Analog To Digital Converters (ADC) Part Context

The ADC10D1000 belongs to the GHz series of ultra-high-speed ADCs, building upon the architecture of previous 8-bit devices like the ADC08D1020. It serves as a successor to earlier National Semiconductor designs now integrated into the Texas Instruments portfolio. The device is pin-compatible with other members of the ADC10D/ADC12D family, facilitating upgrades in existing high-speed data acquisition platforms.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10D1000CIUT/NOPB is a verified lead-free replacement variant with identical electrical specifications. For applications requiring higher speed, the ADC10D1500 offers 1.5 GSPS performance but consumes more power.
