PCM1840IRTWR Description

Short technical summary and product information.

The Texas Instruments PCM1840IRTWR is a high-performance, quad-channel, 32-bit audio analog-to-digital converter (ADC) capable of sampling at rates up to 192 kHz. This Burr-Brown™ audio ADC supports simultaneous sampling of four analog channels, offering differential line and microphone inputs with a 2-V RMS full-scale signal.

 

Key electrical specifications include a maximum sampling rate of 192 kHz, 32-bit resolution, and a typical SNR of 122 dB. It features a THD+N of -98 dB and supports flexible digital audio interfaces such as I2S and TDM, with master or slave interface selection. The device operates with a single supply voltage of 3.3 V and an I/O supply of 3.3 V or 1.8 V.

 

Designed for audio applications, the PCM1840IRTWR integrates essential components like a microphone bias voltage, a phase-locked loop (PLL), and a DC removal high-pass filter. It also includes hardware pin control for filter selection (linear-phase or low-latency) and automatic power-down upon loss of audio clocks to conserve power.

 

The component is housed in a 24-WQFN (4x4 mm) package and is designed for surface mount applications. Its operating temperature range is -40°C to 125°C.
