AD7008 CIRCUIT DESCRIPTION The AD7008 provides an exciting new level of integration for the RF/Communications system designer. The AD7008 com- bines the numerically controlled oscillator (NCO), SINE/CO- SINE look-up tables, frequency, phase and IQ modulators, and a digital-to-analog converter on ...
Page 9
When amplitude modulation is not required, the IQ multipliers can be bypassed (CR = 2). The sine output is directly sent to the 10-bit DAC. Digital-to-Analog Converter The AD7008 includes a high impedance current source 10-bit DAC, capable of driving ...
