HI5805BIB

Analog To Digital Converters (ADC) Overview

The HI5805BIB is a monolithic, 12-bit Analog-to-Digital Converter fabricated in Intersil’s HBC10 BiCMOS process. It features a fully differential pipelined architecture with a front-end differential-in-differential-out sample-and-hold circuit. The device operates at a sampling rate of 5MSPS with a full power input bandwidth of 100MHz. It consumes 300mW of power and includes an internal voltage reference. Digital outputs are TTL/CMOS compatible and support a separate supply voltage ranging from 3.0V to 5.0V. The component is housed in a 28-lead SOIC (W) package and operates within a temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation, as the part was originally produced by Intersil Corporation before its acquisition by Renesas Electronics. Confirm that the specific suffix 'BIB' corresponds to the -40°C to 85°C operating temperature range and the 28-lead SOIC (W) package. Ensure compatibility with the original HBC10 BiCMOS process specifications if performance validation is required for critical designs.

Analog To Digital Converters (ADC) Selection Notes

Select the HI5805BIB when a 12-bit resolution and 5MSPS throughput are required with low power consumption. The fully differential input architecture is suitable for noise-sensitive applications. Ensure the design accommodates the 3-clock-cycle data latency and provides adequate decoupling for the analog and digital supplies. Verify that the system clock duty cycle remains within 50% ±5% to maintain rated dynamic performance.

Analog To Digital Converters (ADC) Part Context

The HI5805 is part of Intersil's high-speed A/D converter family, designed for applications requiring wide bandwidth and low power. The BIB variant specifically denotes the industrial temperature grade (-40°C to 85°C) and the SOIC package style. This component represents a mature technology solution for mid-speed, high-resolution signal conversion tasks prior to the transition to newer CMOS processes.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet explicitly states 'NOT RECOMMENDED FOR NEW DESIGNS' and 'NO RECOMMENDED REPLACEMENT'. Designers should consult technical support or evaluate newer high-speed ADC families from Renesas or other manufacturers for new projects.
