ADC0804S040TS/C1,1

Analog To Digital Converters (ADC) Overview

The ADC0804S040TS is an 8-bit high-speed Analog-to-Digital Converter (ADC) from the ADC0806030/040/050 family, designed for professional video and data acquisition applications. It converts analog input signals into 8-bit binary coded digital outputs at a maximum sampling rate of 40 MHz. The device features low power dissipation of 175 mW (typical) and supports DC sampling with no missing codes guaranteed. Digital inputs and outputs are compatible with TTL and CMOS levels, while the analog input requires no buffer amplifier due to low capacitance.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with a maximum sampling frequency of 40 MHz
• Low power dissipation of 175 mW (typical) at fclk = 40 MHz
• TTL and CMOS compatible digital inputs and 3 V to 5 V CMOS digital outputs
• No sample-and-hold circuit required; one clock cycle conversion only

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component corresponds to the 40 MHz variant within the ADC0804S030/040/050 family. Confirm the package type is SSOP28 (SOT341-1). Ensure the ordering suffix matches the specific speed grade required for the design, as the family includes 30 MHz and 50 MHz versions.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 40 MHz sampling rate is required. The device requires an external source to drive its reference ladder via pins RB, RM, and RT. If internal reference driving is necessary, consider the ADC1003S040 family instead. Ensure supply voltages VCCA and VCCD are maintained between 4.75 V and 5.25 V, while VCCO can range from 3.0 V to 5.25 V.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC0804S030/040/050 family manufactured by Integrated Device Technology (IDT), which was acquired by Renesas Electronics Corporation. The family shares identical pinouts and functional characteristics, differing primarily in their maximum clock frequencies: 30 MHz, 40 MHz, and 50 MHz respectively.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-to-pin compatible alternatives include the ADC0804S030TS (30 MHz) and ADC0804S050TS (50 MHz). For 10-bit resolution requirements, the ADC1004S040TS is a compatible alternative.
