ADC0804S040TS/C1:1

Analog To Digital Converters (ADC) Overview

The ADC0804S040TS/C1:1 is an 8-bit high-speed Analog-to-Digital Converter (ADC) from NXP Semiconductors, designed for professional video and general-purpose applications. It operates with a maximum sampling rate of 40 MHz and converts analog input signals into 8-bit binary coded digital outputs within one clock cycle. The device features low power dissipation of 175 mW typical and requires an external reference voltage regulator to drive its internal resistor ladder. Digital inputs and outputs are compatible with TTL and CMOS logic levels, supporting flexible interface integration.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix /C1:1 against the manufacturer's current ordering information to confirm package availability and tape-and-reel specifications. Ensure that the external reference voltage requirements align with the application design, as this device does not include an internal reference regulator. Confirm supply voltage compatibility with VCCA, VCCD, and VCCO rails before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC0804S040TS variant when a 40 MHz sampling rate is required; use the ADC0804S030TS for 30 MHz or ADC0804S050TS for 50 MHz needs. This component requires an external reference source; if an internal regulator is necessary, consider the ADC1003S040 family instead. Ensure the analog input capacitance is managed without a buffer amplifier due to the device's low input capacitance specification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0804S030/040/050 family of single 8-bit ADCs manufactured by NXP Semiconductors. The family shares identical pinouts and functional architectures, differing primarily in their maximum clock frequencies. The ADC0804S040TS specifically targets applications requiring 40 MHz conversion speeds while maintaining the low-power and high-linearity characteristics of the series.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-to-pin compatible alternatives within the same family include the ADC0804S030TS (30 MHz) and ADC0804S050TS (50 MHz). For designs requiring an internal reference regulator, the ADC1003S040TS (10-bit, 40 MHz) is a suitable alternative, though it offers higher resolution.
