ADS7806U

Analog To Digital Converters (ADC) Overview

The ADS7806U 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 typical power consumption of 28 mW and supports sampling rates up to 40 kSPS. The device features a single-ended input architecture and offers both parallel and serial SPI interface options for data output. It includes an internal reference and operates within a temperature range of -40°C to +85°C. Key performance metrics include a signal-to-noise ratio of 88 dB, differential nonlinearity of -2/3 LSB, and integral nonlinearity of +/- 3 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' indicates the SOIC-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required interface configuration and package type exactly to avoid integration errors in final assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 12-bit resolution at moderate speeds with minimal power draw. Compare against the ADS7807U if 16-bit resolution is necessary, noting the trade-off in speed and complexity. Verify that the single-ended input range aligns with the sensor output levels. Check interface compatibility with the host microcontroller for either parallel or serial operation modes.

Analog To Digital Converters (ADC) Part Context

The ADS7806U belongs to the ADS780x family of low-power sampling ADCs from Texas Instruments. This series is designed for cost-sensitive and power-constrained environments. The 'U' suffix specifically denotes the plastic small-outline integrated circuit (SOIC) package with 28 leads, distinguishing it from other package variants like the ceramic JG package found in other family members.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7807U serves as a higher-resolution alternative within the same family but operates at lower speeds. For direct pin-compatible replacements, verify datasheet specifications carefully as interface timing and power characteristics may differ between SAR architectures.
