ProTek Analog a division of ProTek Devices introduces the PA5331 a Low Power Stereo Audio CODEC with Headphone and Microphone Amplifiers.
The PA5331 is a high performance, low power and low cost audio CODEC. It consists of 2-ch ADC, 2-ch DAC, microphone amplifier, headphone amplifier, digital sound effects, and analog mixing and gain functions.
The PA5331 uses advanced multi-bit delta-sigma modulation technique to convert data between digital and analog.
The multi-bit delta-sigma modulators make the device with low sensitivity to clock jitter and low out of band noise.
The PA5155 is available in a QFN-28 package and is specified for operation over the -40°C to +85°C temperature range.
Sample quantities are available upon request.
