RHF1201:Rad-hard 12-bit 50 Msps 100mW ADC

The RHF1201 is a 12-bit, 50 Msps sampling frequency analog-to-digital converter that uses pure (ELDRS-free) CMOS 0.25 μm technology combining high performance, radiation robustness, and very low power consumption. The device is based on a pipeline structure and digital error correction to provide excellent static linearity. Specifically designed to optimize the speed power consumption ratio, the RHF1201 integrates a proprietary track-and-hold structure making it ideal for IF-sampling applications up to 150 MHz. A voltage reference network is integrated in the circuit to simplify the design and minimize external components. A tri-state capability is available on the outputs to allow common bus sharing. Output data can be coded in two different formats. A Data Ready signal, raised when the data is valid on the output, can be used for synchronization purposes.
