ADS7800KU

Analog To Digital Converters (ADC) Overview

The ADS7800KU is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments, originally part of the Burr-Brown portfolio. It features a single-ended input channel and operates on a parallel interface with a sampling rate of 333 kS/s. The device requires 4.75 V to 5.25 V for both analog and digital power supplies. Key performance metrics include a signal-to-noise ratio of 73 dB, integral nonlinearity of ±0.5 LSB, and differential nonlinearity of ±0.75 LSB. It is housed in a 24-pin SOIC package and includes an internal reference.

• Parallel data interface
• Single-ended input configuration

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Industrial process control
• Medical instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired Burr-Brown. Confirm the specific suffix 'KU' corresponds to the SOIC-24 package and commercial/industrial temperature range (-40°C to +85°C). Ensure compatibility with 5V logic levels due to the parallel interface requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit conversion is required without external reference components. The parallel interface necessitates more GPIO pins compared to serial ADCs. Verify that the system can accommodate the 24-pin SOIC footprint and the 215 mW power dissipation within the thermal design constraints.

Analog To Digital Converters (ADC) Part Context

The ADS7800KU belongs to the ADS7800 series of high-speed ADCs. This series was developed by Burr-Brown before its acquisition by Texas Instruments. The device represents a standalone solution for applications requiring moderate resolution with fast conversion times, distinguishing it from multi-channel or lower-speed SAR ADCs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family may include other variants of the ADS7800 series with different package options or speed grades, provided the interface timing and voltage levels remain compatible.
