What are the key features of PCM1976?
- 24-bit stereo audio ADC with up to 96 kHz sample rate for high-fidelity digital audio capture
- Integrated programmable gain amplifier (PGA) eliminates external op-amp stage, reducing BOM and PCB area
- I2S and left-justified serial audio output interface for direct connection to DSPs and audio processors
What is PCM1976 used for?
PCM1976 is designed for professional and consumer audio capture applications including digital mixing consoles, microphone preamplifiers, and portable recording devices. Its 24-bit resolution at 96 kHz sample rate supports high-fidelity ADC front-ends for studio-quality audio interfaces and broadcast equipment. The integrated PGA simplifies gain staging from microphone-level signals without additional analog circuitry.

Frequently Asked Questions
What sample rate and bit depth does the PCM1976 support for high-fidelity audio recording?
The PCM1976 supports up to 96 kHz sample rate with 24-bit resolution, meeting professional audio standards such as AES and broadcast requirements. This combination provides over 110 dB dynamic range, making it suitable for studio recording interfaces, digital broadcast consoles, and high-resolution portable recorders where audio fidelity is critical.
How does the integrated PGA in the PCM1976 simplify microphone input stage design?
The PCM1976 integrates a programmable gain amplifier that typically covers a range of 0 dB to 20 dB or more, replacing a discrete op-amp stage and reducing external component count by at least 4 to 6 parts. This integration lowers PCB area and simplifies layout for microphone-to-ADC front ends in compact consumer audio devices and portable field recorders.
For a digital mixing console design, when should engineers choose the PCM1976 over a discrete ADC plus op-amp approach?
Select the PCM1976 when board space is constrained to under 50 mm² per channel and when gain control via I2C or SPI is required without a separate PGA chip. The integrated 24-bit ADC at 96 kHz with on-chip PGA reduces channel strip component count by roughly 30%, cutting BOM cost and simplifying PCB routing in 8-channel or 16-channel analog input cards.
