The unit is designed for low cost, high performance applications and requires only an encode signal to achieve 40 MSPS sample rates with 10-bit resolution. Digital inputs and outputs are CMOS compatible; the analog input requires a signal of 2 V p-p amplitude. The two-step architecture used in the AD9040A is optimized to provide the best dynamic performance available while maintaining low power requirements of only 940 mW typically; maximum dissi- pation is 1.1 watt at 40 MSPS. The signal-to-noise ratio (SNR), including harmonics, is 53 dB, or 8.5 ENOB, when sampling an analog input of 10.3 MHz at 40 MSPS. Competitive devices perform at less than 7.5 ENOB and require external references and larger input signals. The AD9040A A/D converter is available as either a 28-lead plastic DIP or a 28-lead SOIC. The two models operate over a commercial temperature range of 0 °C to +70°C. Contact the factory regarding availability of ceramic military temperature range devices.

CMOS compatible logic for direct interface to ASICs. 2. On-board T/H provides excellent high frequency perfor- mance on analog inputs, critical for communications and medical imaging applications. 3. High input impedance and 2 volt p-p input range reduce need for external amplifiers. 4. Easy to use; no cumbersome external voltage references required, allowing denser packing of ADCs for multichannel applications. 5. Available in 28-lead plastic DIP and SOIC packages. 6. Evaluation board includes AD9040AJR, reconstruction DAC, and latches. Space is available near the analog input and digital outputs of the converter for additional circuits.
