ADS7806UB

Analog To Digital Converters (ADC) Overview

The ADS7806UB is a low-power, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 5V supply with an analog and digital voltage range of 4.75 V to 5.25 V. The device features a serial interface compatible with standard SPI protocols and supports sampling rates up to 200 kS/s. It utilizes a single-ended input configuration and includes an internal reference. Key performance metrics include a signal-to-noise ratio of 73 dB and power consumption of approximately 28 mW at full speed. The component is housed in a 20-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 12-bit SAR ADC core with an internal reference for simplified system design.
• Supports flexible serial communication through a standard three-wire SPI-compatible interface.
• Optimized for low-power operation, consuming minimal energy during active sampling and conversion cycles.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring high resolution and low power consumption
• Industrial process control systems utilizing single-supply operation
• Battery-powered data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'UB' corresponds to the standard commercial grade temperature range and SOIC-20 packaging when sourcing. Confirm RoHS compliance status through the manufacturer's current documentation, as environmental declarations may update. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application circuit design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution is sufficient for the application alongside a 200 kS/s sampling rate. It is suitable for designs constrained by a single 5V supply rail. Consider alternative models if differential inputs or higher resolution bits are required, as this part is strictly single-ended and limited to 12 bits.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS780x family of low-power CMOS sampling ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7805 and ADS7807 but offers a specific balance of 12-bit resolution and speed. The family is designed for applications needing moderate precision without the complexity of multi-channel multiplexing.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same series include the ADS7805 and ADS7807, though resolution and speed differ. Verify pin compatibility and electrical parameters before swapping with other 12-bit SAR ADCs from different manufacturers.
