PCM1862DBT

ADCs/DACs - Special Purpose Overview

The PCM1862DBT is a stereo audio analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 192 kHz. The device offers a typical signal-to-noise ratio (SNR) of 103 dB and operates within an analog and digital supply voltage range of 3 V to 3.6 V. It utilizes I2C and SPI interfaces for control and data transfer. The component is housed in a 30-TSSOP package with a width of 4.40 mm, designed for surface-mount installation.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBT' against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration. Ensure that the ordering information matches the exact pinout and thermal characteristics defined for the TSSOP-30 package variant to avoid compatibility issues during assembly.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a stereo channel count with software-controlled interface is required. Compare the 103 dB SNR specification against system noise floor requirements. Verify that the 30-pin TSSOP footprint aligns with the PCB layout constraints and that the operating temperature range meets the environmental specifications of the target application.

ADCs/DACs - Special Purpose Part Context

The PCM1862 belongs to the PCM186x family of audio ADCs from Texas Instruments. This series includes variants such as the PCM1860, PCM1861, PCM1863, PCM1864, and PCM1865, which differ primarily in channel count (stereo vs. quad) and control method (hardware vs. software). The PCM1862 specifically provides a stereo solution with software control capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes within the same family include the PCM1860, PCM1861, PCM1863, PCM1864, and PCM1865. Verify functional equivalence regarding channel count and control interface before substitution. Other PCM18xx series devices may require schematic and firmware adjustments due to differences in pin configurations or operational modes.
