Noise shaping filter DAC

Product specification

TDA1386T

FEATURES

General

• Double-speed mode

• Digital volume control

• Soft mute function

• 12 dB attenuation

• Low power dissipation

• Digital de-emphasis.

Easy application

• Voltage output

• Only 1st-order analog post-filtering required

• Operational amplifiers and digital filter integrated

• 256fs system clock (fsys)

• I2S-bus or 16, 18 or 20 bits LSB fixed serial input format

• Single rail supply.

GENERAL DESCRIPTION

The TDA1386T is a dual CMOS digital-to-analog converter

with up-sampling filter and noise shaper. The combination

of oversampling up to 4fs, noise shaping and continuous

calibration conversion ensures that only simple 1st order

analog post filtering is required.

The TDA1386T supports the I2S-bus data input mode with

word lengths of up to 20 bits and the LSB fixed serial data

input format with word lengths of 16, 18 or 20 bits.

Two cascaded IIR filters increase the sampling rate

4 times.

The DACs are of the continuous calibration type and

incorporate a special data coding. This ensures a high

signal-to-noise ratio, wide dynamic range and immunity to

process variation and component ageing.

Two on-board operational amplifiers convert the

digital-to-analog current to an output voltage.

High performance

• Superior signal-to-noise ratio

• Wide dynamic range

• No zero crossing distortion

• Inherently monotonic

• Continuous calibration digital-to-analog conversion

combined with noise shaping technique.
