ADS7812B/1K

Analog To Digital Converters (ADC) Overview

The ADS7812B/1K is a low-power, serial-output analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and operates with a single 5V supply. The device utilizes a successive approximation register (SAR) architecture to achieve a sampling rate of 40 kS/s. It includes an internal reference voltage and supports SPI-compatible serial interfaces. The component is housed in a 16-pin SOIC package and is designed for applications requiring low power consumption, with a typical power dissipation of 35 mW.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix '1K' indicates reel packaging containing 1000 units. Confirm RoHS compliance status through official datasheets or manufacturer documentation before procurement. Ensure the SOIC-16 package matches the target PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit ADC with low power consumption is required. The internal reference simplifies design compared to external reference variants. Verify that the 40 kS/s sampling rate meets system bandwidth needs and that the SPI interface is compatible with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7812 family of low-power, serial ADCs. The 'UB' suffix typically denotes the SOIC package, while '/1K' specifies the tape and reel quantity. It serves as a cost-effective solution for moderate-speed data conversion tasks where power efficiency is critical.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same family include the ADS7812PB (PDIP package) or ADS7812UB (standard reel). For higher speed requirements, consider the ADS7817 series, though pinouts and interfaces may differ.
