ADS7816UBG4

Analog To Digital Converters (ADC) Overview

The ADS7816UBG4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 200 kS/s and supports both differential and single-ended input configurations. The device utilizes a 3-wire serial interface compatible with standard SPI protocols. It functions within an analog and digital supply voltage range of 4.5 V to 5.25 V. Key performance metrics include a signal-to-noise and distortion ratio (SINAD) of 72 dB, integral nonlinearity (INL) of ±2 LSB, and differential nonlinearity (DNL) of ±2 LSB. Power consumption is specified at 1.9 mW. The component is housed in an 8-pin VSSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the manufacturing date code to verify availability and lifecycle status before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kS/s throughput are sufficient for the application. It is suitable for designs requiring a 3-wire serial interface rather than parallel or higher-pin-count options. Consider the VSSOP-8 package constraints regarding thermal dissipation and board space limitations during the schematic capture phase.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7816 family of high-speed, micro-power ADCs from Texas Instruments. It serves as a successor or variant within the broader ADS78xx series, which includes similar devices like the ADS7817 and ADS7818. The family is characterized by its balance of speed and power efficiency for general-purpose data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7816U is the non-green equivalent part number. Verify pin compatibility if substituting with other ADS78xx series members such as the ADS7817 or ADS7818, noting differences in resolution or interface requirements.
