TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9404FNG
Σ- Modulation System DA Converter with Analog Filter
TC9404FNG is a 2’nd order Σ- modulation system 1-bit DA
converter incorporating an 8-times over sampling digital filter
and analog filter developed for digital audio equipment.
Because the IC includes an analog filter, it can output a direct
analog waveform, thus reducing the size and cost of the DA
converter.
Features
Built-in 8-times over sampling digital filter
Low-voltage operates (3.0 V) possible
Built-in digital de-emphasis filter
In serial mode, output amplitude can be set in 128 steps of
resolution using microcontroller command.
In parallel mode, soft mute can beset for the output signal in 64 steps in 20 ms.
Built-in LR common digital zero detection output circuit
Over sampling ratio (OSR) of Σ- modulation circuit is 192 fs
Support double speed operation
Sampling frequency: 44.1 kHz, 32 kHz, 48 kHz
Built-in 3’rd order analog filter
The digital filter and DA converter characteristics are as follows:
Digital Filter (fs = 44.1 kHz)
DA Converter (VDD = 5 V)
Weight: 0.14 g (typ.)
P-SSOP24-300-0.65A
