FEATURES Ultralow Bias Current: 75 f A max (AD515AL) Ultralow Bias Current: 150 f A max (AD515AK) Ultralow Bias Current: 300 f A max (AD515AJ) Low Power: 1.5 m A max Quiescent Current Low Power: (0.6 m A typ) Low Offset Voltage: 1.0 m V max (AD515AK & L) Low Drift: 15 ␮ V/؇ C max (AD515AK) Low Noise: 4 ␮V p-p, 0.1 Hz to 10 Hz PRODUCT DESCRIPTION Monolithic Precision, Low Power FET-Input Electrometer Op Amp AD515A PIN CONFIGURATION The AD515A is a monolithic FET-input operational amplifier with a guaranteed maximum input bias current of 75 f A (AD515AL). The AD515A is a monolithic successor to the industry standard AD515 electrometer, and will replace the AD515 in most applications. The AD515A also delivers lasertrimmed offset voltage, low drift, low noise and low power, a bination of features not previously available in ultralow bias current circuits. All devices are internally pensated, protected against latch-up and are short circuit protected. The AD515A’s bination of low input bias...
