TDA1386T 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.

TDA1386T Maximum Ratings

SYMBOL	PARAMETER	CONDITIONS	MIN.	MAX.	UNIT
V_DDD	digital supply voltage	note 1	-	7.0	V
V_DDA	analog supply voltage	note 1	-	7.0	V
V_DDO	operational amplifiers supply voltage	note 1	-	7.0	V
T_xtal	maximum crystal temperature			+150	°C
T_stg	storage temperature		-65	+125	°C
T_amb	operating ambient temperature		-40	+85	°C
V_es	electrostatic handling	note 2	-2000	+2000	V

Notes
1. All V_DD and GND connections must be made to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 k series resistor.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 mH series inductor.

TDA1387 General Description

The TDA1387T is a member of a generation of digital-to-analog converters which incorporates the innovative technique of Continuous Calibration. The largest bit currents are repeatedly generated from one single reference current. This duplication is based upon an internal charge storage principle and has an accuracy which is insensitive to ageing, temperature and process variations.

The TDA1387T is fabricated in a 1.0 mm CMOS process and features an extremely low power dissipation, small package size and easy application. The intrinsic high coarse current accuracy combined with the implemented symmetrical offset decoding method preclude zero-crossing distortion and ensure high quality audio reproduction. The CC-DAC is eminently suitable for use in portable digital audio equipment.

TDA1387 Features

` Low power consumption
` Low total harmonic distortion
` Wide dynamic range (16-bit resolution)
` Continuous Calibration (CC) concept
` Single 3 to 5.5 V supply rail
` Output and bias current are proportional to the supply voltage
` Fast settling time enables 2, 4 and 8 times oversampling (serial input) or double-speed operation at 4 times oversampling
` Internal bias current ensures maximum dynamic range
` Wide operating temperature range (-40 to + 85 )
` I²S-bus input format (time multiplex, two's complement, TTL)
` No zero-crossing distortion
` Large DC output voltage compliance
` Contained in small outline package.
