HSP48901JC-30

Overview

The HSP48901JC-30 is a high-speed analog-to-digital converter manufactured by Intersil. It features a sampling rate of 30 MSPS and an 8-bit resolution, utilizing a pipelined architecture for efficient data conversion. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal voltage of 5 V. It supports a propagation delay of 50 ns and functions reliably across an industrial temperature range from -40 °C to +85 °C. The component is housed in a 28-pin plastic dual in-line package (PDIP) with through-hole terminals, designed for robust integration into signal processing systems.

Feature Summary

• Pipelined ADC architecture enabling high-speed data acquisition
• Industrial temperature rating for reliable operation in harsh environments
• Single-supply 5V operation simplifying power design

Applications

• Digital oscilloscopes and test equipment
• Medical imaging systems such as ultrasound
• Wireless communication base stations

Procurement Notes

Verify the specific suffix 'JC' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the supplier provides documentation confirming the component meets the specified industrial temperature grade and voltage parameters before finalizing procurement.

Selection Notes

Select this component when a moderate resolution of 8 bits is sufficient for applications requiring up to 30 MSPS throughput. Consider the PDIP package constraints if board space is limited, or evaluate surface-mount alternatives from the same family if automated assembly is required. Verify power supply stability within the 4.5 V to 5.5 V range to maintain performance.

Part Context

This part belongs to Intersil's HSP489xx series of high-speed analog-to-digital converters. The series is characterized by its use of pipelined technology to achieve high bandwidth while maintaining manageable power consumption. These components were widely used in professional audio and video digitization before being superseded by newer CMOS processes.

Replacement Considerations

Check for direct cross-reference part numbers from Renesas, which acquired Intersil. Evaluate newer generation ADCs with higher effective number of bits (ENOB) if system noise margins are tight. Ensure any substitute maintains the 5V logic interface compatibility.
