It operates from a single 3 V or 5 Vpower supply and features throughput rates up to 833 kSPS or PRODUCT HIGHLIGHTS 1 MSPS, respectively. 1. Operation with either 3 V or 5 V power supplies. This part contains a low noise, wide bandwidth, differential track- 2. High throughput with low power consumption. With a 3 V and-hold amplifier (T/H) that can handle input frequencies in supply, the AD7450 offers 3.75 mW max power consumption excess of 1 MHz with the ­3 dB point typically being 20 MHz. for 833 kSPS throughput. The reference voltage for the AD7450 is applied externally to the 3. Fully differential analog input. VREF pin and can be varied from 100 mV to 3.5 V, dependingon the power supply and what suits the application. The value of 4. Flexible power/serial clock speed management. The conversion
