BU79100G-LATR

Analog To Digital Converters (ADC) Overview

The BU79100G-LATR is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by ROHM Semiconductor. It features a single-ended input and supports sampling rates up to 1 MS/s. The device operates on a supply voltage range of 2.7 V to 5.25 V for both analog and digital domains, consuming approximately 8 mW of power. It utilizes an SPI-compatible serial interface and is housed in a compact SSOP-6 package measuring 2.9 mm x 2.8 mm x 1.25 mm. Key performance metrics include a signal-to-noise ratio of 71.5 dB, full-power bandwidth of 10.1 MHz, and differential/integral nonlinearity of 1 LSB. The operational temperature range spans from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging formats such as tape and reel or cut tape. Confirm that the component status remains recommended for new designs rather than last-time buy or obsolete. Cross-reference the RoHS compliance status and moisture sensitivity level requirements with your assembly process specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution ADC is required with SPI connectivity. Ensure the system design accommodates the 2.7 V to 5.25 V supply voltage range and the -40°C to +85°C operating temperature window. Verify that the 1 MS/s maximum sampling rate meets the application's bandwidth needs and that the external reference voltage configuration aligns with the system's precision requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the BU79100G-LA series of SAR ADCs from ROHM Semiconductor. The 'LA' suffix typically denotes long-term supply agreements for industrial markets. The 'TR' suffix indicates the specific tape-and-reel packaging variant. This series is designed to replace older generation converters while maintaining pin compatibility with similar form factors like SOT-23-6 through its SSOP6 package dimensions.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible replacements within the same family if availability changes. No specific substitute part numbers are publicly confirmed in the provided documentation.
