AD7008JP50

The AD7008JP50 is one member of the AD7008 family which designed as the direct digital synthesis chip that numerically controlled oscillator employing a 32-bit phase accumulator, sine and cosine look-up tables and a 10-bit D/A converter integrated on a single CMOS chip. It can be used in (1)frequency synthes-izers; (2)frequency, phase or amplitude modulators; (3)DDS tuning; (4)digital modulation. Also this device provides an exciting new level of integration for the RF/Communications system designer.

Features of the AD7008JP50 are:(1)single +5 V supply; (2)32-bit phase accumulator; (3)on-chip COSINE and SINE look-up tables; (4)on-chip 10-bit DAC; (5)frequency, phase and amplitude modulation; (6)parallel and serial loading; (7)software and hardware power down options; (8)20 mhz and 50 mhz speed grades; (9)44-pin PLCC.

The absolute maximum ratings of the AD7008JP50 can be summarized as:(1)VAA, VDD to GND:-0.3 V to +7 V;(2)AGND to DGND:-0.3 V to +0.3 V;(3)digital I/O voltage to DGND:-0.3 V to VDD+0.3 V;(4)analog I/O voltage to AGND:-0.3 V to VDD+0.3 V;(5)operating temperature range industrial (A version):-40°C to +85°C;(6)operating temperature range industrial commercial (J version):0°C to +70°C;(7)storage temperature range:-65°C to +150°C;(8)lead temper-ature (soldering, 10 secs):+300°C;(9)junction temperature:+115°C.
