MSM6789规格书详情

GENERAL DESCRIPTION

The MSM6789A/6789L, an improved version of MSM6788, is a solid-state recorder developed using the Sub Band Coding (SBC) method.

Just like MSM6788, the MSM6789A/6789L has a stand-alone mode and a microcontroller interface mode. In the stand-alone mode, record/playback conditions can be selected from pins and the MSM6789A/6789L can be controlled by a simple drive timing. In the microcontroller interface mode, record/playback can be controlled by commands from the microcontroller, and more functions are available than in the stand-alone mode.

FEATURES

• SBC method

• Built-in 12-bit AD converter

• Built-in 12-bit DA converter

• Built-in microphone amplifier

• Built-in low-pass filter

Attenuation characteristics –40 dB/oct

• External memories
