ADA4841-1YRZ-R7

Instrumentation, Op Amps, Buffer Amps Overview

The ADA4841-1YRZ-R7 is a single-channel, unity-gain stable operational amplifier from Analog Devices. It features low power consumption with a maximum quiescent current of 1.5 mA per amplifier and operates within a supply voltage range of 2.7 V to 12 V. The device provides a wideband voltage noise density of 2.1 nV/√Hz and an input current noise of 1.4 pA/√Hz at 100 kHz. It offers a -3 dB bandwidth of 80 MHz (G = +1), a slew rate of 12 V/µs, and a settling time of 175 ns to 0.1%. The output swings rail-to-rail, reaching within 50 mV of either supply rail, while the input common-mode range extends down to the negative supply.
