Parametrics

The AD515A provides subpicoampere bias currents in an
integrated circuit amplifier.
? The ultralow input bias currents are specified as the maxi-mum measured at either input with the device fully warmed
up on ± 15 V supplies at +25° C ambient with no heat sink.
This parameter is 100% tested.
? By using ± 5 V supplies, input bias current can typically be
brought below 50 fA.
2. The input offset voltage on all grades is laser trimmed, typically
less than 500 μV.
? The offset voltage drift is 15 μV/° C maximum on the
K grade.
? If additional pulling is desired, the amount required will
have a minimal effect on offset drift (approximately 3 μV/ °C
per mV).
3. The low quiescent current drain of 0.6 mA typical and
1.5 mA maximum, keeps self-heating effects to a minimum
and renders the AD515A suitable for a wide range of remote
probe applications.
4. The combination of low input noise voltage and very low
input noise current is such that for source impedances from
1M ? to 10
11
? , the Johnson noise of the source will easily
dominate the noise characteristic.
