RS8704XP

The RS870X series zero-crossover distortion, rail-to-rail, high-performance CMOS op amps are optimized for ultralow-voltage, single-supply applications. Rail-to-rail input and output, low noise (4.4uVpp), and high-speed operation (50MHz gain bandwidth) make them ideal for driving sampling ADCs. Applications include audio, signal conditioning, and sensor amplification. This op amp series is also well-suited for mobile phone power amplifier control loops. Special features include excellent common-mode rejection ratio, no input stage crossover distortion, high input impedance, and rail-to-rail input and output swing. The input common-mode range spans both the negative and positive supply rails. These devices are ideal for sensor interfaces, active filters, and portable applications. This op amp series is specified over the full temperature range of -40°C to +125°C and operates from single or dual supplies of 2.2V to 5.5V.
