Low input bias currents, low offset, and low noise result in a wide dynamic range of photodiode amplifier circuits. Low The combination of low offsets, low noise, and very low input noise and distortion, high output current, and excellent speed bias currents makes these amplifiers especially suitable for high make the AD8510/AD8512/AD8513 great choices for audio impedance sensor amplification and precise current measurements applications. using shunts. The combination of dc precision, low noise, and 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 40C to amplifiers, the AD8510/AD8512/AD8513 do not suffer from +125C extended industrial temperature range. output phase reversal when input voltages exceed the maximum common-mode voltage range.
