Preliminary specification

Low-voltage low-power stereo audio ADC

UDA1360TS

FEATURES

General

• Low power consumption

• 2.4 to 3.6 V power supply

• Supports sampling frequency range of 5 to 55 kHz

• Small package size (SSOP16)

• Integrated high-pass filter to cancel DC offset

• Power-down mode

• Supports 2 V (RMS) input signals

• Easy application

• Non-inverting ADC plus decimation filter.

Multiple format output interface

• Up to 20 significant bits serial output.

Advanced audio configuration

• Stereo single-ended input configuration

• High linearity, dynamic range and low distortion.

GENERAL DESCRIPTION

The UDA1360TS is a single chip stereo Analog-to-Digital

Converter (ADC) employing bitstream conversion

techniques. The low power consumption and low voltage

requirements make the device eminently suitable for use

in low-voltage low-power portable digital audio equipment

which incorporates recording functions.

MSB-justified data format with word lengths of up to

20 bits.
