1 / 18 page  June 2007 Rev 2 1/18 18 RHF1201 Rad-hard 12-bit 0.5 to 50 Msps A/D converter Features ■ Wide sampling range: 0.5Msps to 50Msps ■ OptimwattTM adaptive power: 44mW @ 0.5Msps, 100mW @ 50Msps ■ Input range: 2 Vpp differential ■ SFDR up to 75dB @ FS = 50Msps, Fin =15MHz ■ 2.5V / 3.3V compatible digital I/O ■ Built-in reference voltage with external bias capability ■ Hermetic package ■ Rad-hard: 300 kRad(Si) TID ■ Failure immune (SEFI) and latchup immune (SEL) up to 120 MeV-cm2/mg at 2.7V and 125°C ■ Qml-V qualified, smd 5962-05217 Applications ■ Digital communication satellites ■ Space data acquisition systems ■ Aerospace instrumentation ■ Nuclear and high-energy physics Description The RHF1201 is a 12-bit 50MHz maximum sampling frequency analog to digital converter using pure (ELDRS-free) CMOS 0.25µm technology combining high performance, radiation robustness and very low power consumption. The RHF1201 is based on a pipeline structure and digital error correction to provide excellent static linearity and achieve 10.3 effective bits at FS = 50Msps, and Fin = 15MHz. Specifically designed for optimizing power consumption, the RHF1201 can dissipate as little as 100mW at 50Msps, while maintaining a high level of performance. It integrates a proprietary track-and-hold structure to ensure IF-sampling applications up to 150 MHz. A voltage reference 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 which is raised when the data is valid on the output can be used for synchronization purposes. The RHF1201 is available in -55° C to +125° C temperature range, in a small 48-pin hermetic SO-48 package. SO-48 package 24 25 1 48 Pin connections (top view) www.st.com |
