PCM4202DBR

PCM4202DBR is Texas Instruments’ high-performance stereo ADC (analog-to-digital converter) in a RoHS-compliant DBR package. It converts two differential analog inputs to digital audio data with 24-bit resolution using a sigma-delta architecture, designed for high SNR and low distortion.
Key points:
- Two-channel, 24-bit ADC
- Differential analog inputs; programmable gain
- Sampling rates up to about 192 kHz (flexible clocking)
- Flexible digital interface options (I2S/Left-Justified with standard BCLK/LRCK)
- Suitable for professional audio, instrumentation, and embedded audio applications
The DBR suffix denotes the specific package variant. If you need exact electrical specs (SNR, THD+N, input impedance, reference options) or pinout, I can provide them.

Pin count: 28 pins (PCM4202DBR package).
Function: 2-channel, 24‑bit ADC with integrated preamplifier. Converts two analog input channels to digital data and provides a serial digital audio interface (I2S/compatible) with master clock (MCLK), bit clock (BCLK), word/select (LRCLK), and data output (SDOUT), plus the necessary power and control pins (I2C/SPI control as applicable). Supports up to 192 kHz sampling.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and digital integrated circuits, microcontrollers, sensors, and embedded processing solutions. It’s one of the world’s largest semiconductor firms.

- Multi-channel high‑quality audio capture (4-channel ADC)
- Conferencing systems and beamforming microphone arrays
- Automotive infotainment and hands‑free audio front‑ends
- Consumer audio devices (soundbars, home theater, DAC/ADC front ends)
- Professional audio equipment and digital mixers
- Industrial/medical instrumentation and data‑acquisition where high‑resolution, low‑noise ADC is needed
Note: PCM4202DBR is a multi‑channel, high‑performance ADC suitable for these audio and measurement applications.

PCM4202DBR uses a 28-pin QFN package (DBR variant), typically about a 6×6 mm body.
