HI5714/4CB-T

Analog To Digital Converters (ADC) Overview

The HI5714/4CB-T is an 8-bit, high-precision Analog-to-Digital Converter (ADC) manufactured by Intersil using the HBC10 BiCMOS process. It supports sampling rates of 40, 60, 75, or 80 MSPS depending on the specific suffix variant. The device consumes 325mW and achieves a 7.65 ENOB at 4.43MHz. It features three-state TTL outputs for overflow/underflow, operates with low-level AC clocks, and requires no external buffer amplifier or sample-and-hold circuit. The component utilizes parallel access and is housed in a PDSO24 package.

Analog To Digital Converters (ADC) Part Context

The HI5714 series belongs to Intersil's family of high-speed monolithic ADCs. The '/4CB' designation typically indicates a specific sampling rate grade (often 40 MSPS) within the HI5714 line, packaged in a 24-lead plastic small outline (PDSO24). The '-T' suffix denotes tape and reel packaging for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The HI5714 is pin-compatible with the Philips TDA8714. Designers may consider this cross-reference for direct footprint substitution, provided electrical specifications such as sampling rate and power consumption align with the system requirements.
