Key Features
- High throughput rates with low power consumption: The AD7472BR offers 1.5 MSPS throughput while consuming only 4 mW of power.
- Flexible power/throughput rate management: The conversion rate is controlled by an externally applied clock, allowing power reduction as the conversion rate is reduced. The part also features an auto sleep mode for maximum power efficiency.
- No pipeline delays: The ADC features a standard successive approximation architecture with accurate control of the sampling instant via a CONVST input.
- High speed parallel interface: The conversion result is accessed via standard CS and RD signals.
- Low noise, wide bandwidth track-and-hold amplifier: Capable of handling input frequencies in excess of 1 MHz.
