MN6460A
A/D Converter for Digital Audio Equipment
Overview
The MN6460A is a 16-bit CMOS analog-to-digital
converter designed especially for PCM digital audio
equipment. It features a built-in digital filter. It uses noise
shaping to convert an analog signal to a 16-bit digital
signal.
Incorporating digital filter permits simplification of the
analog filter that normally precedes the A/D converter,
thus greatly reducing the power consumption of the
overall A/D conversion system.
Features
Analog and digital-mixed CMOS LSI
A/D conversion using noise shaping
64-fold oversampling
Built-in digital filter
Sample and hold circuit is unnecessary
Serial output using two's complement code
Built-in offset compensation circuit
Built-in overflow limiter
Single 5-volt power supply (when VREF =1.5 V and
AG=2.5 V)
Applications
DAT players and other digital audio equipment

Function Description
Power supply pin for digital circuits (+5 V)
Channel selection pin for stereo operation using two chips.
"H" level: right channel. "L" level: left channel.
Format selection pin. "L" level: signal processing LSI format. "H" level: I2S format.
LRCLK input pin (for stereo operation)
If LR-POL is at "H" level, "H" level: right channel data output.
"L" level, high-impedance state.
If LR-POL is at "L" level, "H" level: high-impedance state.
"L" level, left channel data output.
Bit transfer command input (At falling edge signal, a bit transfered)
Clear pin. Active high.
Driving this pin at "H" level clears internal data. Always this internal
data is cleared by feeding a positive pulse to this pin after applying the power.
Driving this pin at "L" level enables the offset clear circuit.
