Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PCMD3180IRTWR is a high-performance pulse density modulation (PDM) input to Time Division multiplexing (TDM) or I2S output converter, supporting synchronous sampling of up to 8 digital channels of PDM microphone input. The PCMD3180IRTWR converter integrates programmable digital volume control, microphone bias voltage, phase-locked loop (PLL), programmable high-pass filter (HPF), dual second-order filter, and low-latency filter modes, and allows for an output sampling rate up to 768 kHz.

It mainly has the following key parameters

Type: PDM to TDM

Number of channels: 8

Resolution (bit) : -

Sampling rate (per second) : 768k

Data interfaces: I2C, SPI

Power supply voltage source: analog and digital

Voltage - Power supply: 1.7V - 1.9V, 3V - 3.6V, 1.65V - 1.95V, 3V - 3.6V

Operating temperature: -40°C to 125°C

Installation type: Surface mount type

Package/Shell: 24-WFQFN

In addition, the PCMD3180IRTWR is suitable for audio systems with limited space, such as far-field microphone recording, and performs exceptionally well in applications that require high-precision and multi-channel synchronous sampling. Its low latency signal processing and multiple filter options give it a significant advantage in professional audio recording and processing ‌.
