AD8610ARM

PRELIMINARY TECHNICAL DATA a FEATURES Low noise: 6nV/√ Hz Low Offset Voltage: 100µ V max. Low input Bias current 10pA max. Fast settling: 600ns to 0.01% Low Distortion Unity Gain Stable No Phase Reversal Dual supply operation: ±5V to ±13V APPLICATIONS Photodiode Amplifier ATE Instrumentation Sensors and Controls Precision filters High Fidelity Audio Precision Very Low Noise Low Input Bias Current Wide Bandwidth JFET Operational Amplifiers Pr el i m i n ar y Technical Data AD8610 The AD8610 is specified over the extended industrial (-40° to +125°C) temperature range. The AD8610 is available in the 8-lead SOIC and the tiny MSOP8 surface mount packages. MSOP8 packaged devices are available only in Tape-and-Reel. GENERAL DESCRIPTION The AD8610 is a precision JFET input amplifier featuring very low offset voltage and drift, very low input voltage and current noise, very low input bias current and wide bandwidth. Outputs are stable with capacitive loads of over 500pF in non-inverting unity gain. Output swings to within 1.2V of the supplies even with a 1kohm load, maximizing dynamic range with limited supply voltages. Applications for these amplifiers include electronic instruments, ATE front-end amplification and integrator circuits, CAT/MRI/Ultrasound medical instrumentation, photodiode amplification, fast precision filters and professional quality audio.
