GENERAL DESCRIPTION
The AD8510/AD8512/AD8513 are single-, dual-, and quad- Fast slew rate and great stability with capacitive loads make the precision JFET amplifiers that feature low offset voltage, input AD8510/AD8512/AD8513 a perfect fit for high performance bias current, input voltage noise, and input current noise. filters. Low input bias currents, low offset, and low noise result The combination of low offsets, low noise, and very low input in a wide dynamic range of photodiode amplifier circuits. Low bias currents makes these amplifiers especially suitable for high noise and distortion, high output current, and excellent speed impedance sensor amplification and precise current measurements make the AD8510/AD8512/AD8513 great choices for audio using shunts. The combination of dc precision, low noise, and applications. fast settling time results in superior accuracy in medical The AD8510/AD8512 are both available in 8-lead narrow SOIC_N instruments, electronic measurement, and automated test and 8-lead MSOP packages. MSOP-packaged devices are only equipment. Unlike many competitive amplifiers, the AD8510/ available in tape and reel. The AD8513 is available in 14-lead AD8512/AD8513 maintain their fast settling performance even SOIC_N and TSSOP packages. with substantial capacitive loads. Unlike many older JFET The AD8510/AD8512/AD8513 are specified over the −40°C to amplifiers, the AD8510/AD8512/AD8513 do not suffer from +125°C extended industrial temperature range. output phase reversal when input voltages exceed the maximum common-mode voltage range.
