Complete 10-Bit Monolithic Sampling A/D Converter (ADC) with On-Board Track-and-Hold and Reference

The AD9040A is a complete 10-bit monolithic sampling analog-to-digital converter (ADC) with on-board track-and-hold and reference. 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 dissipation 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-pin plastic DIP or a 28-pin 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.
