Overview
The ADA4940-1ACPZ-RL is a fully differential amplifier from Analog Devices, designed as an ultralow power ADC driver. It features a small signal bandwidth of 260 MHz and a slew rate of 95 V/µs. The device operates on flexible power supplies ranging from 3 V to 7 V with a quiescent current of 1.25 mA per amplifier. It provides low input voltage noise of 3.9 nV/√Hz and a maximum offset voltage of 0.35 mV. The component is housed in a 16-lead LFCSP package.
Feature Summary
- Ultralow power consumption suitable for battery-operated applications
- Extremely low harmonic distortion performance
- Adjustable output common-mode voltage level
- Internal common-mode feedback loop for balanced outputs
Applications
- Low power PulSAR/SAR ADC drivers
- Single-ended-to-differential conversion
- Differential buffers
- Line drivers
- Medical imaging systems
Procurement Notes
Verify the specific ordering suffix ACPZ-RL against the manufacturer's official documentation to confirm the package type and reel packaging details. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision E specifications with your design constraints before finalizing procurement.
Selection Notes
Select this component when driving high-resolution SAR or Sigma-Delta ADCs requiring minimal power consumption. The adjustable VOCM pin allows matching various ADC input common-mode voltages. Consider the 16-lead LFCSP package for space-constrained PCB layouts. Verify that the 260 MHz bandwidth aligns with the signal frequency requirements of the target application.
Part Context
The ADA4940-1 is part of the ADA4940 family of fully differential amplifiers manufactured using a SiGe complementary bipolar process. This technology enables low distortion and low noise characteristics. The device is optimized for data acquisition and signal processing applications where power efficiency and signal integrity are critical priorities.
Replacement Considerations
The ADA4940-1ARZ-RL is a comparable single-channel alternative available in an 8-lead SOIC package. Designers should verify pinout compatibility and thermal resistance differences between the LFCSP and SOIC packages when substituting components.
