ORDERING INFORMATION TYPE NUMBER UDA1340M PACKAGE NAME SSOP28 DESCRIPTION plastic shrink small outline package; 28 leads; body width 5.
3 mm GENERAL DESCRIPTION UDA1340 The UDA1340 is a single-chip stereo Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) with signal processing features 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 and playback functions.
The UDA1340 supports the I2S-bus data format with word lengths of up to 20 bits, the MSB-justified data format with w...
