DESCRIPTION

The PCM1804 is a high-performance single chip stereo

A/D converter with full differential analog voltage input.

The PCM1804 uses a precision delta-sigma modulator

and includes a linear phase antialias digital filter and

HPF (low-cut filter) that removes dc offset of the input

signal. The PCM1804 is suitable for a wide variety of

mid-to-high grade consumer and professional

applications, where excellent performance and 5-V

analog supply and 3.3-V digital power supply operation

are required. The PCM1804 can achieve both PCM

audio and DSD format due to precision delta-sigma

modulator. The PCM1804 is fabricated on an advanced

CMOS process and is available in small 28-pin SSOP

package.

Data Formats: Left Justified, I S, Standard

24-Bit and DSD

Function:

– Peak Detection

– Low-Cut Filter (HPF): –3 dB at 1 Hz,

f = 48 kHz

Sampling Rate up to 192 kHz

System Clock: 128 f , 256 f , 384 f , 512 f , or

768 f

Dual Power Supplies:

– 5 V for Analog

– 3.3 V for Digital

Power Dissipation: 225 mW

This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These

circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,

Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated

voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device

should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level,

preferably either V

or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for

Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
