AD8655WARMZ-RL

AD8655WARMZ-RL is a low-noise, precision CMOS amplifier. It leverages the Analog Devices DigiTrim® technology to achieve high dc accuracy. It provides low noise (2.7nV/√Hz at 10KHz), low THD + N (0.0007%), and high precision performance (250µV max over VCM) to low voltage applications. The ability to swing rail-to-rail at the input and output enables designers to buffer analogue-to-digital converters (ADCs) and other wide-dynamic range devices in single-supply systems. The high precision performance of the device improves the resolution and dynamic range in low-voltage applications. Audio applications, such as microphone pre-amps and audio mixing consoles, benefit from the low noise, low distortion, and high output current capability of the device to reduce system-level noise performance and maintain audio fidelity. It is used in applications such as ADC and DAC buffers, audio, industrial controls, precision filters, digital scales, automotive collision avoidance, and PLL filters.
