AD8655ARMZ Description
The AD8655ARMZ is a precision CMOS amplifier with the lowest noise in the market. To achieve high dc precision, they use Analog Devices' DigiTrim? technology.
Low voltage applications benefit from the AD8655ARMZ's low noise (2.7 nV/Hz at 10 kHz), low THD + N (0.0007 percent), and excellent precision performance (250 V max over VCM). Designers can buffer analog-to-digital converters (ADCs) and other wide dynamic range devices in single-supply systems by having the capacity to swing rail-to-rail at the input and output.
The AD8655ARMZ's high precision performance enhances low voltage applications' resolution and dynamic range. The low noise, low distortion, and high output current capabilities of the AD8655ARMZ help to improve system level noise performance and retain audio integrity in audio applications like microphone pre-amps and audio mixing consoles. The data acquisition, process controls, and PLL filter applications benefit from the AD8655ARMZ's high precision and rail-to-rail input and output.
The temperature range of 40°C to +125°C is covered by the entire specification of the AD8655ARMZ. The AD8655ARMZ are offered in 8-lead MSOP and SOIC packaging that are Pb-free. Both versions of the AD8655ARMZ are accessible for automotive applications.
