RHF1401KSO-01V

抗辐射的14位20Msps的85mW的A / D转换器 Rad-hard 14-bit 20Msps 85mW A/D converter

The RHF1401 is a 14-bit 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 RHF1401 is based on a pipeline structure and digital error correction to provide excellent static linearity. Specifically designed to optimize power consumption, the device only dissipates 85 mW at 20 Msps, while maintaining a high level of performance. The device also integrates a proprietary track-and-hold structure to ensure a large effective resolution bandwidth.

Voltage references are 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. A data-ready signal, which is raised when the data is valid on the output, can be used for synchronization purposes.

The RHF1401 has an operating temperature range of -55° C to +125° C and is available in a small 48-pin ceramic SO-48 package.
