RHF1201中文资料抗辐照12位50 Msps A/D转换器数据手册ST规格书

描述 Description

The RHF1201 is a 12-bit, 50 Msps sampling frequency analog-to-digital converter that uses pure CMOS 0.25 μm technology combining high performance 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.

The analog and digital power supplies operate from 2.7 V to 3.6 V, drawing a current consumption of 1.65 mA typ. and 2 mA max. only.

A data ready signal, raised when the data is valid on the output, can be used for synchronization purposes.
