AD1847JP

Overview

The AD1847JP is a dual-channel, high-performance analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a resolution of 16 bits and supports sampling rates up to 200 kSPS. The device utilizes a differential input architecture with a full-scale input range of ±10 V. It operates on a single +5 V power supply and includes an internal voltage reference. The component is housed in a 28-pin plastic DIP package and is designed for applications requiring precise data acquisition.

Feature Summary

• Dual-channel simultaneous sampling capability
• Internal precision voltage reference
• Differential input configuration

Applications

• Industrial process control systems
• Data acquisition modules
• Test and measurement equipment

Procurement Notes

Verify the specific suffix JP indicates the plastic DIP package variant. Confirm RoHS compliance status as legacy parts may have varying environmental declarations. Check for obsolescence notices or last-time buy notifications from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when dual-channel isolation is required within a single package. Ensure the system design accommodates the ±10 V differential input range. Verify that the SPI-compatible digital interface aligns with the host microcontroller's communication protocols.

Part Context

The AD1847 belongs to Analog Devices' family of monolithic ADCs. It serves as a compact solution for multi-channel sensing tasks. The part integrates both analog front-end and digital logic on a single CMOS die.

Replacement Considerations

Check for direct pin-compatible upgrades such as the AD1847AJP if tighter accuracy specifications are needed. Evaluate newer generations like the AD76xx series for improved performance metrics.
