ADS7806P

Analog To Digital Converters (ADC) Overview

The ADS7806P is a monolithic, high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 500 kSPS and utilizes a successive approximation register (SAR) architecture. The device operates with a single +5 V power supply and includes an internal voltage reference and track-and-hold amplifier. It communicates via a standard SPI-compatible serial interface. The ADS7806P is housed in a 16-pin DIP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'P' indicates the plastic DIP package variant when sourcing. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for RoHS compliance status if required for your assembly process. Ensure the ordering part number matches the exact pin count and package style needed for your PCB footprint.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 500 kSPS speed are sufficient for the application. Consider it for designs requiring a single +5 V supply and minimal external components. Evaluate alternatives if higher resolution or faster sampling rates are necessary. Verify that the serial interface timing meets the microcontroller's capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS7806 belongs to the ADS78xx family of high-speed ADCs from Texas Instruments. This family offers various resolutions and speeds, sharing similar architectural features like SAR conversion and integrated references. The ADS7806 specifically targets cost-sensitive, medium-speed applications requiring reliable performance in industrial environments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements may include other parts within the ADS78xx series with compatible pinouts and specifications. Verify electrical parameters such as sampling rate and resolution before substitution. Ensure the package type matches or adapt the design for different footprints if using a pin-compatible alternative.
