ADA4941-1YCPZ-R2

Overview

The ADA4941-1YCPZ-R2 is a single-supply, differential ADC driver manufactured by Analog Devices Inc. in an 8-lead LFCSP package. It operates within a supply voltage range of 2.7 V to 12 V and features a gain bandwidth product of 31 MHz at G = +2. The device provides a slew rate of 22 V/µs and settles to 0.005% for a 2 V step in 300 ns. Key electrical parameters include a common-mode rejection ratio of 105 dB, an input bias current of 4.5 µA, and an output offset voltage of 0.8 mV maximum. It draws 2.2 mA quiescent current at 3 V and supports a disable feature with low standby consumption.

Feature Summary

• Converts single-ended signals to differential outputs for high-resolution analog-to-digital converters
• Provides excellent linearity with distortion as low as -110 dBc at 100 kHz
• Features extremely low power consumption suitable for battery-operated systems
• Includes a user-adjustable gain configuration via external feedback network

Applications

• Single-supply data acquisition systems
• Battery-power systems
• Medical instrumentation
• Process control applications

Procurement Notes

Verify the specific suffix YCPZ-R2 corresponds to the 8-lead LFCSP package and reel packaging format. Confirm the operating temperature range matches the extended industrial specification of -40°C to +125°C. Ensure the component is sourced from authorized distributors to guarantee authenticity and compliance with RoHS standards. Cross-reference the datasheet revision D specifications against your design requirements.

Selection Notes

Select this component when driving 16-bit or 18-bit PulSAR ADCs requiring low noise and high linearity. The device is optimized for single-supply operation with rail-to-rail output swing. Consider the 24 MΩ input impedance and adjustable gain capabilities for interface flexibility. Evaluate thermal performance based on the 83°C/W junction-to-ambient resistance in the LFCSP package.

Part Context

The ADA4941-1 belongs to the family of differential amplifiers designed specifically for driving high-resolution analog-to-digital converters. Manufactured using Analog Devices' second-generation XFCB process, it achieves 18-bit performance at low supply currents. The series includes variants like the ADA4941-1YRZ in SOIC packages, offering designers flexibility in form factor while maintaining consistent electrical characteristics for precision signal chain applications.
