ADC0804S050TS/C1:1

Analog To Digital Converters (ADC) Overview

The ADC0804S050TS/C1:1 is an 8-bit high-speed Analog-to-Digital Converter (ADC) from NXP Semiconductors, capable of sampling rates up to 50 MHz. It converts analog input signals into 8-bit binary coded digital outputs within a single clock cycle. The device operates with separate analog and digital supply voltages, typically VCCA/VCCD at 5 V and VCCO between 3 V and 5 V. Key electrical characteristics include a typical power dissipation of 175 mW, low analog input capacitance of 5 pF, and guaranteed no missing codes. It features TTL and CMOS compatible digital inputs and outputs, allowing for flexible interface integration in professional video and data acquisition systems.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with maximum sampling rate of 50 MHz
• Single clock cycle conversion time without sample-and-hold circuit
• Low analog input capacitance (5 pF), eliminating the need for buffer amplifiers
• TTL and CMOS compatible digital inputs and outputs

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 the specific suffix /C1:1 against the manufacturer's current ordering information to confirm package type and tape/reel specifications. Ensure that the analog and digital supply pins are properly decoupled with capacitors placed close to the device as per the application diagram guidelines. Confirm that the external reference voltage ladder is correctly connected to pins RB, RM, and RT to maintain linearity performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 50 MHz sampling speed are required. It is suitable for applications where low input capacitance is critical to avoid signal attenuation without buffering. Note that this device requires an external source to drive the reference ladder; if internal reference regulation is needed, consider the ADC1003S050 family instead. Ensure the design accommodates separate analog and digital ground planes for optimal noise performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0806030/040/050 family of 8-bit high-speed, low-power ADCs designed for professional video and other high-frequency applications. The '050' designation indicates a maximum clock frequency of 50 MHz, distinguishing it from the 30 MHz (ADC0804S030TS) and 40 MHz (ADC0804S040TS) variants within the same series. All members share identical pinouts and functional characteristics regarding resolution and power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-to-pin compatible alternatives include the ADC0804S030TS (30 MHz) and ADC0804S040TS (40 MHz). For higher resolution requirements, the ADC1004S050TS offers 10-bit resolution at 50 MHz but requires an external reference source. If an internal reference regulator is desired, the ADC1003S050TS is a recommended alternative.
