AD6644AST-65

The AD6644AST-65 is one member of the AD6644 family which is designed as the 14-bit, 40 MSPS/65 MSPS A/D converter that can be used in (1)multichannel, multimode receivers; (2)AMPS, IS-136, CDMA, GSM, third generation; (3)single channel digital receivers; (4)antenna array processing; (5)communications instrumentation; (6)radar, infrared imaging; (7)instrumentation applications. This device is also built on Analog Devices' high-speed complementary bipolar process (XFCB) and uses an innovative, multipass circuit architecture.

Features of the AD6644AST-65 are:(1)65 MSPS guaranteed sample rate; (2)40 MSPS version available; (3)sampling jitter < 300 fs; (4)100 dB multitone SFDR; (5)1.3 W power dissipation; (6)differential analog inputs; (7)two's complement format; (8)3.3 V CMOS-compatible; (9)data ready for output latching.

The absolute maximum ratings of the AD6644AST-65 can be summarized as:(1)AVCC Voltage: 0 to 7 V;(2)DVCC Voltage: 0 to 7 V;(3)Analog Input Voltage: 0 to AVCC V;(4)Analog Input Current: 25 mA;(5)Digital Input Voltage: 0 to AVCC V;(6)Digital Output Current: 4 mA;(7)Operating Temperature Range: -25 to +85 °C;(8)Maximum Junction Temperature: 150 °C;(9)Lead Temperature (Soldering, 10 sec): 300 °C;(10)Storage Temperature Range (Ambient): -65 to +150 °C.
