ADCs/DACs - Special Purpose datasheet and documents for PCM1774RGPR
ADCs/DACs - Special Purpose Overview
The PCM1774RGPR is a stereo audio digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a delta-sigma architecture with 16-bit resolution and supports sampling rates up to 50 kHz. The device integrates a headphone amplifier and operates on a single supply voltage ranging from 2.4 V to 3.6 V. Key electrical specifications include a signal-to-noise ratio of 93 dB and a typical operating current of 10 mA. It utilizes I2C or SPI interfaces for control and is housed in a 20-pin VQFN package.
ADCs/DACs - Special Purpose Feature Summary
- Integrated headphone amplifier for direct driver capability
- Low-power operation with 10 mA typical supply current
- Supports I2C and SPI digital control interfaces
- 93 dB signal-to-noise ratio performance
ADCs/DACs - Special Purpose Applications

ADCs/DACs - Special Purpose Procurement Notes
Verify the specific suffix RGPR against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range of -40°C to 85°C for the intended application environment.
ADCs/DACs - Special Purpose Selection Notes
Select this component when a low-power, integrated solution for stereo audio conversion is required. The built-in headphone amplifier eliminates the need for external amplification stages, reducing board space and component count compared to DACs without integrated drivers.
ADCs/DACs - Special Purpose Part Context
This part belongs to the PCM1774 series of low-power stereo DACs. Variants such as PCM1774RGPT and PCM1774RGPRG4 share similar electrical characteristics but differ in packaging type or compliance markings. The RGPR suffix specifically denotes the VQFN EP package with tape-and-reel delivery.
ADCs/DACs - Special Purpose Replacement Considerations
Direct pin-compatible substitutes within the same family include PCM1774RGPT. Cross-family replacements require verification of interface compatibility and power supply requirements.
