TDA8779 - NXP

TDA8779 10-bit converter interface ADC/DAC for quadrature transceiver

TDA8779 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 mid.

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.
