JFET technology. The 10
鈩?/div>
common-mode impedance,
resulting from a bootstrapped input stage, insures that input
bias current is essentially independent of common-mode voltage
variations.
The AD546 is suitable for applications requiring both minimal
levels of input bias current and low input offset voltage. Appli-
cations for the AD546 include use as a buffer amplifier for cur-
rent output transducers such as photodiodes and pH probes. It
may also be used as a precision integrator or as a low droop rate
sample and hold amplifier. The AD546 is pin compatible with
standard op amps; its plastic mini-DIP package is ideal for use
with automatic insertion equipment.
The AD546 is available in two performance grades, all rated
over the 0擄C to +70擄C commercial temperature range, and
packaged in an 8-pin plastic mini-DIP.

by Patent No. 4,639,683.
1. The input bias current of the AD546 is specified, 100%
tested and guaranteed with the device in the fully warmed-up
condition.
2. The input offset voltage of the AD546 is laser trimmed to
less than 1 mV (AD546K).
3. The AD546 is packaged in a standard, low cost, 8-pin
mini-DIP.
4. A low quiescent supply current of 700
碌A(chǔ)
minimizes any
thermal effects which might degrade input bias current and
input offset voltage specifications.
