Product Summary
1. The AD549’s input currents are specified, 100% tested and
guaranteed after the device is warmed up. Input current is
guaranteed over the entire common-mode input voltage
range.
2. The AD549’s input offset voltage and drift are laser trimmed
to 0.25 mV and 5 μV/ ° C (AD549K), 1 mV and 20 μV/ ° C
(AD549J).
3. A maximum quiescent supply current of 700 μA minimizes
heating effects on input current and offset voltage.
4. AC specifications include 1 MHz unity gain bandwidth and
3 V/ μs slew rate. Settling time for a 10 V input step is 5 μs to
0.01%.
5. The AD549 is an improved replacement for the AD515,
OPA104, and 3528.
