GENERAL DESCRIPTION
The TDA8779 contains two 10-bit high speed ADCs and two 10-bit DACs for wireless communication (for use in transceiver modules). This device converts two analog input signals (channels I and Q) and digital inputs (D0 to D9) at a maximum sampling rate of 20 MHz. The input bias voltages for the analog input voltages are provided internally at the middle code. The analog input and output voltages are AC coupled.

FEATURES
• Two 10-bit ADCs with multiplexed outputs
• Two 10-bit DACs with multiplexed inputs
• Sampling rate for the ADCs and DACs up to 20 MHz
• Digital outputs (for the ADC) and inputs (for the DAC) are TTL/CMOS compatible (2.7 to 5.5 V)
• Internal reference voltage regulator
• Power dissipation 520 mW
• Standby mode.

APPLICATIONS
    Wireless communication.
