The RS870X-Q1 zero-crossover series, rail-to-rail, high performance, CMOS operational amplifiers are optimized for very low voltage, single-supply applications. Rail-to-rail input or output, low-noise (4.4uVpp) and high-speed operation (50MHz Gain Bandwidth) make these devices ideal for driving sampling analog-to-digital converters (ADCs). Applications include audio, signal conditioning, and sensor amplification. The RS870X-Q1 family of op amps are also well-suited for cell phone power amplifier control loops.
