AD4110-1BCPZ-RL

Overview

The AD4110-1BCPZ-RL is a single-channel universal input analog front end with an integrated 24-bit Sigma-Delta ADC, manufactured by Analog Devices Inc. It supports high-voltage inputs up to ±10 V and currents up to ±20 mA, alongside thermocouple and RTD interfaces. The device operates on dual supplies of ±12 V to ±20 V and a +5 V analog supply. Key electrical parameters include a maximum output data rate of 125 kSPS, simultaneous 50 Hz/60 Hz rejection, and overvoltage protection up to ±30 V. It features internal diagnostics for open wire detection and thermal shutdown within a 40-lead LFCSP package.

Feature Summary

• Universal high-voltage input configurable for ±10 V voltage, ±20 mA current, thermocouples, and RTDs
• Integrated 24-bit Sigma-Delta ADC with output data rates from 5 SPS to 125 kSPS
• Internal diagnostic functions including overvoltage, undervoltage, open wire, and overtemperature detection
• Field power supply capability for loop-powered sensors and no-power-supply mode operation

Applications

• Process control and industrial automation systems
• Remote and distributed control systems (DCS)
• Industrial instrumentation and measurement equipment
• Sensor and data acquisition modules

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm that the B-grade variant meets the required gain error and drift specifications for your application. Ensure the system power supply architecture supports the required ±12 V to ±20 V range for VDD/VSS and +5 V for AVDD5. Check for moisture sensitivity level requirements during storage and reflow soldering processes.

Selection Notes

Select this component when a single channel requires flexibility to interface with multiple sensor types, including high-voltage signals and resistive sensors. The internal programmable gain amplifier offers 16 gain settings from 0.2 to 24. Consider the 40-lead LFCSP package constraints and the need for external reference voltage if higher precision than the internal 2.5 V reference is required. Evaluate the serial interface compatibility with SPI, QSPI, MICROWIRE, or DSP protocols.

Part Context

The AD4110-1 belongs to Analog Devices' family of universal input analog front ends designed for industrial process control. It replaces legacy discrete solutions by integrating the analog front end, PGA, and 24-bit ADC into a single chip. The BC suffix typically denotes a specific grade or temperature range variant within the ADF/AD4110 series, ensuring consistent performance across industrial environments.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific high-voltage input architecture. Review datasheets for other AD411x variants or similar industrial ADCs with integrated AFEs. Verify that alternative components support the same ±10 V input range and RTD excitation current capabilities.
