AD8643ARZ, Precision Amplifiers Quad Low Pwr Low Ibias R-R Out Jfet AMP

AD8643 is a low power, precision JFET input amplifier featuring extremely low input bias current and rail-to-rail output. The ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables designers to buffer complementary metal-oxide semiconductor digital-to-analogue converters (CMOS DACs), ASICs, and other wide output swing devices in single-supply systems. This device is suitable for applications utilizing multichannel boards that require low power to manage heat. Other applications include photodiodes, ATE reference level drivers, battery management, and industrial controls. It is widely used in application such as line/battery-powered instruments, photodiode amplifiers, precision current sensing, medical instrumentation, industrial controls, precision filters, portable audio, ATE etc. • Supply current/amplifier is 195µA typ• Very low input bias current is 0.25pA typ• Low offset voltage is 50µV typ• Single-supply operation is 5V to 26V• Dual-supply operation is ±2.5V to ±13V• Rail-to-rail output, unity-gain stable, no phase reversal• Voltage noise is 4µV p-p typ• Common-mode rejection ratio is 93dB typ at (VCM = 0V to 2.5V)• Operating temperature is -40°C to +125°C• Packaging style is 14-lead standard small outline package [SOIC• N]
