HI5714/4CBZ

Analog To Digital Converters (ADC) Overview

The HI5714/4CBZ is an 8-bit, high-precision Analog-to-Digital Converter (ADC) fabricated using Intersil’s advanced HBC10 BiCMOS process. It supports sampling rates of 40, 60, 75, and 80 MSPS with a low power consumption of 325mW. The device achieves a Signal-to-Noise Ratio (SNR) of 7.65 ENOB at 4.43MHz. It features three-state TTL outputs for overflow/underflow conditions and operates with low-level AC clocks. The design eliminates the need for external buffer amplifiers or sample-and-hold circuits due to very low analog input capacitance.

Analog To Digital Converters (ADC) Feature Summary

• Sampling rates configurable at 40, 60, 75, or 80 MSPS
• Low power consumption of 325mW
• TTL compatible I/O with three-state overflow/underflow outputs
• Pin-compatible with Philips TDA8714

Analog To Digital Converters (ADC) Applications

• Video digitizing systems
• QAM demodulators
• Digital cable set-top boxes
• Medical ultrasound imaging
• Communication systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific sampling rate variant required (40/60/75/80 MSPS) as the suffix may denote performance binning. Confirm RoHS compliance status if Pb-free certification is mandatory for the assembly process. Ensure the PDSO24 package matches the PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with up to 80 MSPS throughput is needed without external sample-and-hold circuitry. It is suitable for applications requiring low analog input capacitance and direct TTL interfacing. Consider the 325mW power dissipation in thermal management calculations.

Analog To Digital Converters (ADC) Part Context

This part belongs to the HI5714 family of monolithic ADCs from Intersil (now Renesas). It is designed for high-speed data conversion tasks where simplicity and low power are critical. The device replaces older discrete solutions by integrating the conversion logic and output drivers into a single BiCMOS chip.

Analog To Digital Converters (ADC) Replacement Considerations

The HI5714/4CBZ is pin-compatible with the Philips TDA8714. Verify electrical parameter compatibility before substitution.
