ADA4841-2YRMZ-R7

Overview

The ADA4841-2YRMZ-R7 is a dual, unity-gain stable, low power, low noise and distortion, rail-to-rail output amplifier. It features a quiescent current of 1.5 mA maximum per amplifier, with a wideband voltage noise of 2.1 nV/√Hz and current noise of 1.4 pA/√Hz at 100 kHz. The device offers an 80 MHz bandwidth (G = +1), 12 V/µs slew rate, and 0.3 mV maximum input offset voltage. It operates on supply voltages from 2.7 V to 12 V and supports capacitive loads up to 15 pF with minimal peaking.

Feature Summary

• Low power consumption with 1.1 mA typical quiescent current per amplifier
• Ultra-low wideband noise performance for precision signal integrity
• Rail-to-rail output capability extending within 50 mV of supply rails
• High linearity with -105 dBc harmonic distortion at 100 kHz

Applications

• Battery-powered instrumentation systems
• Drivers for 16-bit PulSAR ADCs
• Low power, low noise signal processing circuits

Procurement Notes

Verify the specific ordering suffix YRMZ-R7 corresponds to the 8-lead MSOP package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliant lead finish requirements. Ensure the industrial temperature range rating of -40°C to +125°C aligns with your system environmental specifications before finalizing procurement.

Selection Notes

Select this component when both low power consumption and high precision are required in a dual-channel configuration. The ADA4841-2 provides matched characteristics between channels, including input offset voltage matching of 70 µV. It is suitable for applications requiring rail-to-rail output swing on single or dual supplies, such as portable medical devices or industrial measurement systems where channel count and power efficiency are critical constraints.

Part Context

This part belongs to the ADA4841 family of amplifiers, which includes the single-channel ADA4841-1 and the dual-channel ADA4841-2. The family shares identical electrical specifications, noise profiles, and architectural features. The primary distinction lies in the number of amplifiers per package and the presence of a power-down pin, which is available on the ADA4841-1 but not utilized in the dual-channel ADA4841-2 variant.
