AD708

超低失调电压双通道运算放大器 Ultralow Offset Voltage Dual Op Amp

GENERAL DESCRIPTION

The is a high precision, dual monolithic operational amplifier. Each amplifier individually offers excellent dc precision with maximum offset voltage and offset voltage drift of any dual bipolar op amp.

The matching specifications are among the best available in any dual op amp. In addition, the AD708 provides 5 V/μV minimum open-loop gain and guaranteed maximum input voltage

noise of 350 nV p-p 0.1 Hz to 10 Hz. All dc specifications show excellent stability over temperature, with offset voltage drift typically 0.1 μV/°C and input bias current drift of

25 pA/°C maximum.
