PCM69AP-KG4

ADCs/DACs - Special Purpose Overview

The PCM69AP-KG4 is a dual-channel, 18-bit audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It utilizes Pulse Code Modulation (PCM) serial interface for data input and operates on a single 5V supply. The device is housed in a 16-pin Plastic Dual In-line Package (PDIP-16) with a standard 0.300-inch (7.62mm) width. Designed for high-fidelity audio applications, it supports sampling rates up to 96 kHz. The component is classified as obsolete and is no longer in active production.

ADCs/DACs - Special Purpose Procurement Notes

This component is officially discontinued and no longer manufactured by Texas Instruments. Verification of authenticity is critical when sourcing from secondary markets, as availability is limited to surplus or recycled stock. Buyers should confirm the specific revision and physical condition of the unit, as original packaging may not be available. Cross-referencing datasheets is recommended to ensure pinout and electrical specifications match the target design requirements before procurement.

ADCs/DACs - Special Purpose Selection Notes

Designers requiring this specific 18-bit architecture must account for the obsolescence status during the selection phase. While the PCM69AP-KG4 offers 18-bit resolution, modern alternatives often provide higher bit depths such as 24-bit. Engineers should evaluate whether upgrading to a current-generation DAC family is feasible. If replacement is necessary, verify that the substitute component maintains compatible voltage levels, interface protocols, and package dimensions to minimize board redesign efforts.

ADCs/DACs - Special Purpose Part Context

The PCM69 series represents an older generation of audio DACs from Texas Instruments, previously produced under the Burr-Brown brand. The PCM69AP-KG4 specifically denotes the lead-free, RoHS-compliant variant within the PDIP-16 package family. This part belongs to a lineage of components designed for professional audio applications prior to the widespread adoption of higher-resolution 24-bit converters.

ADCs/DACs - Special Purpose Replacement Considerations

Texas Instruments lists the PCM1793DB as a similar alternative. However, the PCM1793DB is also marked as obsolete. Designers should consult current product portfolios for modern replacements, ensuring that any substitute matches the required 18-bit performance or exceeds it while maintaining interface compatibility.
