Product Introduction
The ADA4841-1/ADA4841-2 are unity-gain stable, low noise, low distortion, rail-to-rail output amplifiers with a maximum quiescent current of 1.5mA. These amplifiers offer low power consumption along with 2.1nV/√Hz low broadband voltage noise and 1.4pA/√Hz current noise, delivering an excellent −105dBc SFDR at 100kHz. To maintain a low-noise environment at lower frequencies, the amplifiers exhibit low 1/f noise of 7nV/√Hz and 13pA/√Hz at 10Hz.
The ADA4841-1/ADA4841-2 feature output swing to within 50mV of each supply rail, an input common-mode voltage range that extends to the negative supply voltage, and the ability to drive capacitive loads up to 10pF with minimal peaking.
They deliver the performance needed to effectively support the latest 16-bit to 18-bit ADCs, making them ideal for portable instrumentation, high channel count, industrial measurement, and medical applications, and are well suited for driving the 16-bit PulsAR ADC AD7685/AD7686.
