AD4110-1BCPZ-RL7

Overview

The AD4110-1BCPZ-RL7 is a single-channel, universal input analog-to-digital front end featuring a 24-bit Sigma-Delta ADC. It supports ±20 mA current and ±10 V voltage inputs with integrated RTD excitation and thermocouple interfaces. The device includes a programmable gain amplifier (PGA) with gains from 0.2 to 24, internal diagnostics for overvoltage and open wire detection, and field power supply capabilities. Operating on dual supplies of ±12 V to ±20 V and +5 V logic, it delivers data rates up to 125 kSPS with simultaneous 50 Hz/60 Hz rejection in a 40-lead LFCSP package.

Feature Summary

• Universal Input: Software-configurable for ±20 mA, ±10 V, thermocouples, and RTDs.
• High Voltage Protection: Overvoltage protected up to ±30 V with internal current limiting.
• Integrated Diagnostics: Detects overrange, undervoltage, open wire, and overtemperature conditions.
• Precision ADC: 24-bit resolution with output data rates from 5 SPS to 125 kSPS.

Applications

• Process control and industrial automation systems
• Remote and distributed control systems
• Instrumentation and measurement equipment
• Sensor and data acquisition modules

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm that the operating environment requires the specified dual power supply range of ±12 V to ±20 V for the analog section and +5 V for digital I/O. Ensure PCB layout accounts for the exposed pad connection to VSS for thermal and mechanical stability.

Selection Notes

Select this component when high-voltage industrial signals require direct interface without external isolation or complex front-end conditioning. Consider the internal RTD excitation currents and field power supply features if designing loop-powered sensor interfaces. Verify that the required data rate and noise performance align with the available digital filter settings, such as Sinc5+Sinc1 for maximum resolution.

Part Context

This part belongs to the AD4110-1 family of universal input analog front ends designed for industrial process control. It integrates the analog front end, PGA, and 24-bit ADC into a single chip, replacing discrete solutions. The BCPZ designation identifies the 40-lead, 6 mm × 6 mm Lead Frame Chip Scale Package (LFCSP) variant.
