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 compatible; the analog PRODUCT HIGHLIGHTS 1. CMOS compatible logic for direct interface to ASICs. 2. On-board track-and-hold provides excellent high frequency performance on analog inputs, critical for communications 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 dynami...
