The CD8655/CD8656 are the industry's lowest noise, precision CMOS amplifiers. They can achieve high dc accuracy. The CD8655/CD8656 provide low noise(2.7nV/ ? at 10 kHz), low THD + N (0.0007%), and high precision performance (250 µV max over VCM) to low voltage applications. The ability to swing rail-to-rail at the input and output enables designers to buffer analog-to-digital converters (ADCs) and other wide dynamic range devices in single- supply
systems. The high precision performance of the CD8655/CD8656 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 CD8655/CD8656 to reduce system level noise performance and maintain audio fidelity. The high precision and rail-to-rail input and output of the CD8655/ CD8656 benefit data acquisition, process controls, and PLL filter applications. The CD8655/CD8656 are fully specified over the −40°C to+125°C temperature range. The CD8655/CD8656 are available in Pbfree, 8-lead MSOP and SOIC packages. The CD8655/CD8656 are both available for automotive applications.
