ADC0801S040TS/C1'1

Analog To Digital Converters (ADC) Overview

The ADC0801S040 is an 8-bit universal analog-to-digital converter designed for video and general-purpose applications. It converts analog input signals ranging from 2.7 V to 5.5 V into 8-bit binary-coded digital words at a maximum sampling rate of 40 MHz. The device features CMOS/TTL compatible digital inputs and outputs, allowing direct interface with standard logic families. It includes a sleep mode that reduces power consumption to 4 mW, while typical active power dissipation is 30 mW. The ADC does not require an external sample-and-hold circuit or buffer amplifier due to low analog input capacitance.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required form factor, as the ADC0801S040 is available in an SSOP20 plastic shrink small outline package (SOT266-1). Confirm supply voltage requirements align with the 2.7 V to 5.5 V operating range for analog, digital, and output stages. Ensure clock frequency specifications do not exceed the 40 MHz maximum limit during system design validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with high-speed conversion up to 40 MHz is required. It is suitable for applications needing CMOS or TTL logic compatibility without additional level shifting. Consider the low analog input capacitance if driving directly from sensors without buffering. Verify that the thermal resistance of 120 K/W in free air meets the ambient temperature constraints for the specific enclosure design.

Analog To Digital Converters (ADC) Part Context

The ADC0801S040 is manufactured by NXP Semiconductors. The specific model suffix TS indicates the SSOP20 package variant. This device belongs to a family of single-channel ADCs optimized for video processing tasks where moderate resolution and high speed are prioritized over ultra-high precision.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult NXP Semiconductors for current equivalent products or cross-reference based on pinout and electrical specifications if alternative sources are considered.

Analog To Digital Converters (ADC) FAQ

Does the ADC0801S040 require an external sample-and-hold circuit?

No, the device does not require a sample-and-hold circuit because it has low analog input capacitance.

What is the effective number of bits (ENOB) at a 4.43 MHz input frequency?

At an input frequency of 4.43 MHz with a clock frequency of 40 MHz, the effective number of bits is 7.3.

How is the reference voltage configured?

The reference voltage is set using three pins: RB (Bottom), RM (Middle), and RT (Top). An external resistor ladder can be used to derive these voltages from the supply.
