GENERAL DESCRIPTION The AD8510/AD8512/AD8513 are single-, dual-, and quad precision JFET amplifiers that feature low offset voltage, input bias current, input voltage noise, and input current noise. The combination of low offsets, low noise, and very low input bias currents makes these amplifiers especially suitable for high impedance sensor amplification and precise current measurements using shunts. The combination of dc precision, low noise, and fast settling time results in superior accuracy in medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the AD8510/AD8512/AD8513 maintain their fast settling performance even with substantial capacitive loads. Unlike many older JFET amplifiers, the AD8510/AD8512/AD8513 do not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range. FEATURES Fast settling time: 500 ns to 0.1% Low offset voltage: 400 μV maximum Low TCVOS: 1 μV/°C typical Low input bias current: 25 pA typical at VS= ±15 V Dual-supply operation: ±5 V to ±15 V Low noise: 8 nV/√Hz typical at f = 1 kHz Low distortion: 0.0005% No phase reversal Unity gain stable APPLICATIONS Instrumentation Multipole filters Precision current measurement Photodiode amplifiers Sensors Audio
