ADA4841-2YRMZ

Overview

The ADA4841-2YRMZ is a dual-channel, unity gain stable, low noise and distortion, rail-to-rail output amplifier from Analog Devices Inc. It operates on a wide supply range of 2.7 V to 12 V with a quiescent current of 1.5 mA maximum per amplifier. Key electrical parameters include an 80 MHz bandwidth (G = +1), 12 V/µs slew rate, and 2.1 nV/√Hz input voltage noise. The device features a power-down function in the single-channel variant, though this model is dual. It supports capacitive loads up to 15 pF with minimal peaking and operates within an industrial temperature range of −40°C to +125°C.

Feature Summary

• Low power consumption with 1.1 mA/amp quiescent current
• Rail-to-rail output capability extending to less than 50 mV of either supply rail
• Low wideband noise performance of 2.1 nV/√Hz and 1.4 pA/√Hz current noise
• High speed operation with 80 MHz bandwidth and excellent linearity

Applications

• Battery-powered instrumentation
• 16-bit PulSAR ADC drivers
• Low power, low noise signal processing

Procurement Notes

Verify the package type matches the RM designation (8-Lead MSOP) and ensure the suffix YRMZ corresponds to the specific reel or tape configuration required for your assembly process. Confirm that the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision G for any updates to ordering information or thermal characteristics before finalizing procurement.

Selection Notes

Select this component when low noise and high precision are critical alongside low power consumption. The dual-channel configuration is suitable for differential signal paths or multi-channel data acquisition systems. Ensure the application does not require more than 15 pF of capacitive load without additional compensation. Consider the single-channel ADA4841-1 if power-down functionality is needed for one channel only.

Part Context

The ADA4841-2YRMZ belongs to the ADA4841 family of low-power, precision amplifiers fabricated on ADI's second-generation XFCB process. This family includes the single-channel ADA4841-1 and the dual-channel ADA4841-2. The YRMZ suffix indicates the 8-lead MSOP package variant. These amplifiers are designed for applications requiring high resolution and precision in portable and battery-operated devices.
