ADC1241CIJ

Analog To Digital Converters (ADC) Overview

The ADC1241CIJ is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input and utilizes an external reference voltage. The device operates on dual ±5V power supplies for both analog and digital sections. It employs a parallel data interface and integrates a sample-and-hold function with a 1:1 ratio. The component is housed in a 28-lead ceramic dual in-line package (CDIP) designed for through-hole mounting, supporting an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

The ADC1241CIJ is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status. Compliance notes indicate the part does not meet RoHS standards. Engineers should confirm lead times and sourcing channels carefully due to the component's retired status.

Analog To Digital Converters (ADC) Selection Notes

Designers must account for the specific ±5V dual supply requirement, which differs from modern single-supply low-voltage ADCs. The parallel interface necessitates multiple I/O lines compared to serial alternatives. The 28-CDIP package limits PCB density. Ensure the application supports the thermal range of -40°C to +85°C and that the system can accommodate the legacy form factor and non-RoHS compliance if required by regulations.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC124 family of 12-bit ADCs from Texas Instruments. It represents a legacy solution utilizing ceramic DIP packaging, contrasting with contemporary plastic surface-mount packages. The device serves as a high-reliability option for environments requiring robust physical connectors and established SAR performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

As an obsolete part, direct pin-compatible replacements are not publicly confirmed in standard catalogs. Designers may need to evaluate newer ADC12 series devices with serial interfaces, accepting potential schematic redesigns for interface and supply voltage differences.
