ADS7800JU/1K

Analog To Digital Converters (ADC) Overview

The ADS7800JU/1K is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input architecture and operates with parallel digital interfaces. The device supports sampling rates up to 333 kS/s with a typical sampling period of 3 microseconds. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V, consuming approximately 135 mW of power. Key performance metrics include a signal-to-noise ratio of 73 dB and a signal-to-noise and distortion ratio of 72 dB. Differential nonlinearity is specified at +/- 0.75 LSB, while integral nonlinearity is +/- 0.5 LSB. The component is housed in a SOIC-24 package and includes an internal reference.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal voltage reference eliminates the need for external components
• High-speed 12-bit resolution with 3 microsecond sampling capability
• Parallel interface design for direct connection to microprocessors

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high accuracy
• Data acquisition modules for sensor interfacing
• Medical instrumentation equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'J' indicates commercial temperature grade (-40°C to +85°C) and 'U/1K' denotes the SOIC-24 tube packaging quantity of 1000 units. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a 12-bit resolution with fast 333 kS/s throughput is required in a parallel interface environment. Compare against the ADS7804U/1K if reel packaging or slightly different linearity specs are preferred. Verify that the single-ended input configuration matches the system signal requirements rather than differential applications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7800 series of high-speed ADCs from Texas Instruments. It shares architectural similarities with the ADS7804 and ADS7805 but offers distinct resolution and speed characteristics. The 'JU/1K' designation specifically identifies the commercial grade variant in a standard tube package, distinguishing it from industrial or tape-and-reel alternatives.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7804KU/1K serves as a functional alternative within the same family, offering similar 12-bit resolution and parallel interface capabilities. Verify pin compatibility and check if the slight differences in linearity specifications meet the application requirements before substitution.
