HI5812JIB

Analog To Digital Converters (ADC) Overview

The HI5812JIB is a 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It features a single-ended input configuration with a sampling rate of 50 kSPS. The device operates on a single 5V analog and digital power supply. It utilizes an external reference voltage architecture and supports parallel data output interfaces. The component is housed in a 24-pin Dual In-line Package (DIP) with a 0.300-inch (7.62 mm) width, designed for through-hole mounting. The specified operating temperature range extends from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

The HI5812JIB is classified as a discontinued product by the manufacturer. Verification of availability requires checking distributor inventories for remaining stock or Last Time Buy status. Compatibility checks must confirm pinout alignment with legacy designs using the 24-DIP form factor. Sourcing should prioritize authorized channels to ensure component authenticity given the end-of-life status.

Analog To Digital Converters (ADC) Selection Notes

Designers selecting this component must account for its SAR architecture and parallel interface requirements. The need for an external voltage reference adds bill-of-materials complexity compared to internal reference devices. The 50 kSPS throughput limits suitability for high-speed applications. Engineers should verify that the 24-DIP package fits within the mechanical constraints of the target PCB layout and enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the HI5812 family of 12-bit SAR ADCs. The JIB suffix typically denotes specific packaging and temperature grade variations within the broader HI5812 series. Related components in the Renesas portfolio include other SAR ADCs with varying resolutions and interface types, such as serial SPI-based models, which may offer smaller footprints but different performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements are limited due to the specific 24-DIP package and parallel interface. Potential substitutes require evaluation of resolution, sampling rate, and reference type. Alternative packages such as TQFP or LQFP may necessitate schematic and layout redesigns. Verify if newer generation SAR ADCs with integrated references can meet the system timing and accuracy requirements.
