The unit is designed for low cost, high perfor- Emance applications and requires only an encode signal to achieve T40 MSPS sample rates with 10-bit resolution. EDigital inputs and outputs are CMOS patible; the analog PRODUCT HIGHLIGHTS 1. CMOS patible logic for direct interface to ASICs. 2. On-board track-and-hold provides excellent high frequency performance on analog inputs, critical for munications and medical imaging applications. 3. High input impedance and 2 V p-p input range reduce need for external amplifiers. input requires a signal of 2 V p-p amplitude. The two-step 4. Easy to use; no cumbersome external voltage references architecture used in the AD9040A is optimized to provide the required, allowing denser packing of ADCs for multichannel best dynamic performance available while maintaining low applications. power requirements of only 940 m W typically; maximum dissi- 5.
