ADC1003S040TS/C1,1

Analog To Digital Converters (ADC) Overview

The ADC1003S040TS/C1,1 is a single-channel 10-bit high-speed Analog-to-Digital Converter (ADC) from the ADC1003S family. It operates with a maximum sampling rate of 40 MHz and includes an internal voltage reference regulator. The device converts analog input signals into 10-bit binary-coded digital words using Transistor-Transistor Logic (TTL) and CMOS compatible interfaces. Key electrical parameters include a typical power dissipation of 235 mW at 40 MHz, an effective number of bits (ENOB) of 9.3 at 4.43 MHz full-scale input, and supply voltages of 5 V for analog/digital sections and 3 V to 5 V for outputs.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit resolution with a maximum sampling frequency of 40 MHz
• Internal voltage reference regulator eliminates external reference requirements
• High signal-to-noise ratio achieving 9.3 effective bits at 4.43 MHz input frequency
• Low analog input capacitance (5 pF) allowing direct connection without buffer amplifiers

Analog To Digital Converters (ADC) Applications

• Video data digitizing
• Radar systems
• Transient signal analysis
• Global Positioning System (GPS) receivers
• Medical imaging equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix /C1,1 against manufacturer documentation to confirm tape-and-reel packaging or temperature grade variations. Confirm RoHS compliance status as datasheets may vary by revision. Check for obsolescence notices as this component family originates from Integrated Design Technology (IDT), now part of Renesas Electronics.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC1003S040TS variant specifically for applications requiring a 40 MHz clock limit; the ADC1003S030 supports 30 MHz and the ADC1003S050 supports 50 MHz. Ensure the design accommodates separate 5 V analog/digital supplies and a 3 V to 5 V output supply. Consider the ADC1004S040 if external reference driving is required instead of the internal regulator.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1003S030/040/050 family of single 10-bit ADCs originally published by Integrated Design Technology (IDT). The datasheet indicates IDT copyright, though the brand is listed as Renesas Electronics Corporation in current market contexts. The 'TS' designation indicates the SSOP28 plastic shrink small outline package.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC1003S030TS (30 MHz) and ADC1003S050TS (50 MHz). For external reference configurations, the ADC1004S040 is a pin-compatible alternative. Higher speed options like the ADC1005S060 (60 MHz) are also available but require verification of timing constraints.
